direct combustion of shell material is easier and less time consuming than acidification. In museum collections bivalve shells are traditionally dry stored, whereas soft tissues are preserved in 70% ethanol, sometimes after fixation with 10% formalin. However, often the whole animal is preserved in ethanol and shells are not stored separately. For the application of these preserved specimens in the investigation of past d N values it is essential to know if liquid preservation methods have an effect on the d N values of bivalve shells and if this effect is predictable. The effects of liquid preservation on the d N values of biological tissues have been examined in a variety of For testing the in uence of CaCO 3 content on d N measurements, different mixtures of acetanilide with inorganic pure CaCO 3 were made, containing between 0 and 10.

4 weight % N. Powder calcite samples were loaded into 4 _ 6 mm tin cups and weighed. d N values were measured using an elemental analyzer coupled via a CONFLO III to a ThermoFinnigan Delta V t isotope ratio mass spectrometer. An inline soda lime CO trap was used to scrub MLN8237 CO 2 from the gas stream entering the gas chromatography column of the EA. IAEA N1 was used as a standard, with an accepted value of 0. 4 _ 0. 2% Long term. standard reproducibility is better than 0. 1% for samples nature, even samples between 5 and mg N provided reasonable data. There is also an upper limit to the amount of shell material that can be loaded into the EA, but this was not evaluated here.

This method is robust because calcium carbonate com pletely decomposes around 8258C and the ash combustion Nilotinib in the EA was around 10208C, therefore, all N should be released from the matrix and carried to the IRMS. Moreover, previous studies have used an EA IRMS system to combust Fig. 2 that the narrow and near symmetrical peak shapes are similar for both shell carbonate and synthetic mixtures, which suggests that both matrices are reacting similarly in the EA IRMS. We therefore argue that it is possible to measure carbonates for d C analysis. It is clear from the traces in larger than 30 mg N. d N values are expressed in % vs. atmospheric nitrogen. Pure synthetic CaCO 3 had peaks similar to empty tin cups, empty tin cup 1/4 0. 49 Vs) and therefore did not contribute much to the calculated delta values. The acetanilide standard had a d N value of 2.

In addition, during a preliminary trial, we ran 0. 4 mg of the IAEA N1 ammonium sulfate SO 4) standard in. 72 mg CaCO 3 and found no offset from N1 standards run without CaCO3. Our results show that samples with as little as 20 mg N can provide accurate d N values. Prior acidification is not required to eliminate the carbonate matrix to produce accurate results, as has been previously reported. It should be noted that mollusks with very low organic matrix in their shells may require a pre concentration step to reduce the poorer precision of small samples. However, considering the large fractionations associated with nitrogen isotopes in Figure 1.

Mass Spectrom. 2011, 25, 675 680 Letter to the Editor tissue is subject to metabolic turnover and is thus repre sentative for a specific time window, see e. g., Paulet et al,. while the shell samples averaged at least 1 year of growth. This makes comparing soft tissues with shell organic matrix difficult. However, as shown in Delong and Thorp, tissues with slower turnover rates, such as the adductor muscle, are better for comparisons with metabolically inactive shells.

Most previous studies that report differences between skeletal d N and soft tissue d N do not take the different amounts of time being averaged into consider ation. Moreover, HSP many studies compare whole body tissue d N data to shell data while it is known that different organs can have quite different d N values, sometimes as much as 5% in the same animal. This may explain why Dtissue shell values for the same species of clam range from 0. 2 to 2. 4%, see ODonnell et al.. Soft tissue d N data from M. edulis specimens collected at three different periods in 2002 from Knokke show significant changes throughout the year, which would be averaged in the shell samples we analyzed. Taking the average of these 25 soft tissue data results in a Dtissue shell value of _1. 5 _ 1. 0%. In the future it is important to compare tissues and shells that represent the same time period.

Growth of Candida xestobii in minimal medium in the presence of 50 g mL metolachlor and in MM with metolachlor plus sucrose y east extract, or sucrose plus yeast extract. Metolachlor degradation by Candida xestobii in MM in the presence of 50 g mL metolachlor i n MM plus sucrose, yeast extract, and sucrose plus yeast extract, and in control medium containing metolachlor but without added inoculum. Metolachlor MRM transitions were as follows: 283. 8 M t H 284. 2 252. 2 and 284. 2 176. 2. Minimal matrix effects were observed. RESULTS AND DISCUSSION Metolachlor, a member of the chloroacetanilide class of herbicides, contains 15 carbon atoms and one nitrogen atom per molecule and, thus, can potentially serve as a nutrient source for microbial growth.

Nilotinib However, despite its use over the past 30 years, only a relatively few microorganisms that can incompletely transform metolachlor have been identified. This was thought to be due, in part, to its sorptive behavior, lack of bioavailability, and requirements for co meta bolism in the presence of microbial consortia. In the study reported here, we describe the isolation and identification of two microorganisms that were capable of using metolachlor as the sole source of C for growth. Both microbes were isolated, via enrichment, from the same Spanish soil with a history of metolachlor application. Microscopic and molecular analyses showed that the isolated organisms were a bacterium and a yeast. The bacterium was a Gram positive, spore forming, microorganism, and 16S rRNA sequence analysis confirmed the isolate was B.

simplex, with 99% nucleotide sequence similarity. The identification of the yeast was much more difficult, in part due to incomplete and complicated taxonomy of yeasts isolated from natural substrates, such as soil. Consequently, they are extremely difficult to differentiate phenotypically and are very often misidentified. Sequence analysis of 18S Entinostat and 26S rDNA and the ITS region led to the conclusion that the isolated yeast was C. xestobii, with 99% nucleotide similarity in the GenBank CBS Yeast databases. Because only 2 bp differentiate C. xestobii and Pichia guillier mondii in the D1/D2 and ITS regions, species identity was confirmed by using biochemical analyses. The isolated yeast grew in MM containing glucose, sucrose, D xylose, trehalose, maltose, starch, and galactose, but failed to grow on rhamnose, inositol, lactose, D mannitol, and D arabinose.

Results of these analyses were consistent with taxonomic assignment of the yeast to C. xestobii. Growth and Degradation of Metolachlor by C. xestobii and B. simplex. The influence of culture media and carbon sources on the degradation of 50 g mL metolachlor was examined. The dis appearance of metolachlor PI3K Inhibitors was determined to be due to microbial metabolism. Results in Figure 2A show that as C. xestobii grew in MM amended with metolachlor, with or without other added amendments, the concentration of metolachlor decreased to 40% of the initial concentration after 6 days of incubation. No further degradation of metolachlor was observed after this time.

Control media, which were not inoculated, did not exhibit metolachlor disappearance, in agreement with previous reports that metolachlor degradation is mainly due to biological rather than chemical processes. The greatest amount and fastest rate of metolachlor PI3K Inhibitors degradation wereobservedinmetolachlormediumamendedwith 0. 04% of yeast extract. In contrast, whereas growth of the yeast was faster and greatest in metolachlor medium amended with sucrose and yeast extract, only about 20% of metol achlor was degraded after 9 days of incubation. Taken together, these results indicated that the yeast has the ability to catabolize metolachlor as a sole source of nutrients for growth, but preferred other nutrient sources, suchas yeast extract and sucrose, whichare probablyeasiertometabolize. Because the yeast also grew in MM amended only with metolachlor, data presented in Figure 2 also show that C.

xestobii uses metolachlor as a sole C source for growth. To our knowledge, this is the first reported yeast that has the ability to catabolize metolachlor and use this compound as sole C metolachlor. metolachlor, these cultures demonstrated a faster rate of degradation than that seen with the initial degradation of the compound. This indicated that C. FDA xestobii more actively degraded metolachlor following initial growth on this substrate, perhaps due to either the presence of more cells or the induction of enzymes required for metolachlor degradation. Results in Figure 4 show that B. simplex also grew in metola chlor medium, with or without added amendments. The initial concentration of metolachlor decreased 65% after 6 days of incubation, after which time no further degradation of the compound was observed.

The degradation of metolachlor by B. simplex was approximately 25% less than that observed with the yeast under the same conditions. The degradation rate of metolachlor was similar in the different culture media used, despite the greater growth observed when the growth medium containing metolachlor was amended with yeast extract or with sucrose plus yeastextract.

Toxicities that were reported included nausea, vomiting, diarrhea, fatigue/asthenia, anemia, and anorexia, these effects were mild or moderate, manageable, and reversible upon treatment discontinuation. AUC and Cmax were found to increase non proportionally with dose and were variable within and among patients. NVP BEZ235 exhibited dose and day dependent PI3K inhibition as measured by elevation of plasma C peptide levels. 2 partial responses and 16 measurable responses were observed. ABT-888 Veliparib 14 of 51 evaluable patients had stable disease for ?? months, tumours from 6 of these 14 patients carried dysregulation of the PI3K pathway. Four of the 14 patients with stable disease for ?? months had breast cancer. 18 of 35 evaluable patients . An improved formulation of the compound will be used in future studies.
XL765 was administered twice daily or daily for 28 day cycles with a standard 33 dose escalation design in patients with solid tumours and lymphoma. The most common related adverse events were observed to be nausea, AZD8330 diarrhoea, anorexia, elevated liver enzymes, skin disorders, and vomiting. Exposure was found to be increased with increasing doses on BID and QD schedules. Robust pharmacodynamic modulation of PI3K and ERK pathway signalling was evident both in tumours and surrogate tissues following dosing of XL765. For example, decreases in phosphorylation of AKTTHR308 or of 4EBP1, as well as ERK, were observed in paired biopsies of various solid tumours from patients receiving 50 mg BID. Eleven patients have been reported to be on study for ??16 weeks and seven patients on treatment for ??24 weeks. The maximum tolerated dose for single agent XL765 is reported as 50 mg BID.
XL765 exhibited potent pharmacodynamic activity in solid tumours and surrogate tissues at generally well tolerated doses. XL765 in combination with the DNA methylating agent temozolomide is well tolerated at doses up to 40 mg QD. There was no apparent pharmacokinetic interaction between XL765 and temozolamide. Maximum tolerated dose determinations for QD and BID schedules are ongoing. Signs of disease stabilisation have been observed. XL765 in combination with erlotinib is also generally well tolerated at daily doses up to 50 mg XL765/100 mg erlotinib with no apparent pharmacokinetic interaction, and results in robust inhibition of PI3K and EGFR signalling in skin and tumour tissue. The maximum tolerated dose for the combination has not yet been determined.
The phase I dose escalation study of GDC 0980 was carried out in patients with solid tumours or non Hodgkin,s lymphoma and used a 33 design. GDC 0980 was given on day 1, followed by 1week washout to investigate single dose pharmacokinetic and pharmacodynamic biomarkers. The most frequently reported adverse events were nausea, fatigue, diarrhoea, and flatulence. GDC 0980 was found to be generally well tolerated up to 16 mg administered orally QD with potential signs of anti tumour activity. Preliminary pharmacokinetic data suggest dose proportional increases in Cmax and AUC. Initial pharmacodynamic biomarker data showed 50% inhibition of phosphorylated AKTSER473 levels assayed in platelet rich plasma after a single dose of 8 mg and higher of GDC 0980. Of potential interest, evidence of anti tumour activity was observed in a mesothelioma patient previously treated with radiation and cisplatin.

The initial culture had an OD600 of 0. 10, and resuspended infresh buffertoan OD600 of1. 0. Metolachlor disappearance and metabolite formation were determined by HPLC analysis. Analyses were performed using a Waters high performing liquid chromatograph equipped with a C 18 5 m column and a UV photodioarray detector. For the detection of the metolachlor, the isocratic mobile phase consisted of water and acetonitrile. The flow rate was 1. 0 mL min, the column was operated at room temperature, and the injection volume was 50 L. Metolachlor was detected at 210 nm after approximately 5. 8 min. For the detection of the acetochlor, the isocratic mobile phase consisted of water and methanol at a flow rate of 1. 0 mL min, the column was operated at room temperature, and the injection volume was 25 L.

Acetochlor was detected at 200 nm after approximately 4. 8 min. For the MEK Inhibitors detection of the alachlor, the isocratic mobile phase consisted of water and acetonitrile at a flow rate of 1. 0 mL min, the column was operated at room temperature, and the injection volume was 25 L. Alachlor was detected at 205 nm after approximately 6. 5 min. Mineralization of the metolachlor and alachlor ring structures was determined in 250 mL biometer flasks containing 10 mL of 25 mM phos phate buffer. Bacteria and yeast cells obtained from cultures grown on metolachlor or alachlor were added to final concentrations of 10 9 or 10 cells mL, respectively. Metolachlor or alachlor was added to flasks to a final concentration of 50 g mL and metolachlor or alachlor was added to a final concentration of 3000 dpm mL.

A 7 mL vial LY-411575 containing 5 mL of 0. 5 N NaOH was placed into the biometer flasks to quantify CO 2 released. The vials containing NaOH were removed and replaced at selected times during the incubation period. To determine CO 2, a 1 mL aliquot of the NaOH solution was mixed with 6 mL of Ecolite cocktail and radioactivity was quantified by using a Beckman model LS 6800 scintillation counter. Samples were held in the dark for 24 48 h prior to counting and were corrected for quenching. No chemiluminescence was observed. The buffer medium was analyzed for the presence of metolachlor or alachlor and potential metabolites by HPLC as described below. Mass Balance Determination. After the final sampling period, the solution in biometer flaskswas dried to a constantweight at 80 C for 24h.

Duplicate aliquots of the dried samples were weighed and mixed with an DNA Damage equal volume of powdered micro crystalline cellulose powder CF 11, and samples were oxidized for 1. 4 min using a model 306 sample oxidizer. The CO 2 evolved during combus tion process was trapped in Carbosorb solvent, mixed with Permafluor in a liquid scintillation vial, and quantified by using a Beckman model LS 6800 scintillation counter. The instrument combustion efficiency was determined before and after the combustion of each set of test samples. The efficiency of the oxidizer was calculated on the basis of the recovery of radioactivity from cellulose containing a known quantity of metolachlor or alachlor, and averaged 97. 0% during the course of the study. LC MS Analysis.

The concentration of metolachlor and its metabo lites in growth medium was determined by using HPLC and LC MS analyses. The HPLC analyses were done as described above. The LC MS analysisfor lossofparentcompoundmetolachlor was doneusing a Waters Alliance 2695 high performance liquid GPCR Signaling chromatograph, coupled to an Applied Biosystems API 3200 LC MS MS. A Zorbax RX C8 column was used for separa tion. The column temperature was maintained at 40 C, and the mobile phase was a gradient starting with 95% water /5% acetonitrile, 95% A at 0 min, 95% A at 5 min, 50% A at 10 min, 3% A at 15 min, 3% A at 20 min, 95% A at 25 min, and 95% A at 30 min. The mobilephaseflowratewas 0. 2 mLmin, and thesampleinjectionvolume was 50 L. Samples were maintained at 10 C in the autosampler to minimize decomposition.

Tuning parameters were optimized by direct infusion.

xestobii wasalsoshownheretorapidlymineralizeup to 25% of metolachlor after 10 days of growth. Because differ ences in mineralization rates among microorganisms in soils are likely due to both biotic and abiotic factors, more studies are needed to assess the contribution of mineralization to loss of this herbicide in soils. Results of mass balance analyses indicated that 5% of metolachlor in the culture medium was present in C. xestobii and B. simplex cells following incubation with metolachlor. This result indicated that metolachlor was not significantly incorporated into biomass and, thus, metabolites that were not mineralized were likely released into the growth medium. Our results are in contrast to those reported in ref 17, which reported that 80% of ring labeled metolachlor added to a microbial community was removed from the medium and accumulated inside cells.

Mechanism of Degradation. The mechanism by which metola chlor is transformed by C. xestobii is not clear. Because Pazopanib analytical standards of possible metolachlor metabolites were not available, we used the University of Minnesota Biocatalysis/Biodegrada tion Database Pathway Prediction System to predict plausible pathways for the microbial degradation of metola chlor. The PPS identi fied 22 possible molecules with molecular ions 190. Comparison of the possible molecular ions from the total ion current plot of culture medium obtained following growth of C. xestobii on metolachlor resulted in no positive matches. Also, HPLC fractionation of the spent medium following growth of C.

xestobii in uniformly ring labeled metolachlor did not result in any peaks that had 2% of the applied C, other than the metolachlor Pazopanib peak, leading to difficulty in extrapolating a degra dation pathway. Although it is tempting to speculate that dechlorination was not a major mechanism for the degradation of metolachlor by the isolated yeast, too few data are available to accurately determine this. Consequently, the pathway by which metolachlor is transformed by C. xestobii is currently unknown and awaits further analyses. In summary, in this study we report on the isolation of a bacte rium and yeast that have the ability to catabolize metolachlor. We also show that the yeast C. xestobii uses metolachlor as a sole C and energy source for growth and is able to mineralize t. this compound under controlled laboratory conditions.

Although otherfungalandbacterialstrainshavebeenisolatedthatareableto Cannabinoid Receptor partially transform metolachlor, most attempts to isolate pure or mixed microbial cultures capable of mineralizing metolachlor have been unsuccessful. Whereas the degradation of metola chlor has been previously studied with a pure culture of the fungus Ch. globosum, which also used this herbicide as a sole source of C and energy, gas liquid chromatographic analysis of the concen trated extract from resting cell experiments with this fungus showed that at least eight extractable products were produced fromtheoriginalcompound. TiedjeandHagedorn reported that the major product of alachlor degradation by this fungus was likely 2,6 diethyl N aniline, and McGahen and Tiedje reported that the co metabolism of metolachlor by Ch.

globosum is thought to occur by removal of one or both R groups from the nitrogen atom and subsequent dehydrogenation of the ethyl substituent. These authors also postulated that the HDAC-42 fungus may eventually remove the chloro, methoxy, or ethoxy substituent from the R groups. In addition to fungi, bacteria have also been reported to transform alachlor. For example, Sette et al. reported that a Streptomycetes sp. strain degraded ??60 75% of the alachlor within days to produce indole and quinoline deriv atives, and Villareal et al. reported that Moraxella sp. strain DAK3 respired and grew on N substituted acylanilides containing methyl, ethyl, or isopropyl substitutions, but failed to grow on alachlor and metolachlor. In contrast to previous studies with fungi, the isolated C.

xestobii strain degraded 50% of metolachlor after 4 days of growth, and no metabolites, such as the ethanesulfonic acid and oxanilic acid, were detected in the growthmediumbyHPLCanalysis. A. flavus and A. terr ??cola PARP have been also described as metolachlor degrading fungi, reducing the half life of this herbicide from 189 to 3. 6 and 6. 4 days, respec tively. Coupled with data showing that some fungicides significantly reduce metolachlor dissipation in soils, results from our studies are consistent with the notion that soil yeast and other fungi may be responsible for significant transformation of metolachlor in soils. Moreover, because degradation of metola chlor by C. xestobii was fairly rapid and resulted in the miner alization of this herbicide, our data suggest that this yeast may eventually prove to be useful for metolachlor bioremediation efforts. More studies, however, are needed to determine whether this yeast is also able to metabolize and mineralize other aniline herbicide compounds and to identify metabolites produced dur ing the degradation process.

Yao and Shiu constructed a mediator type glucose sensor based on the immobilization of GOx at electropolymerized poly film on CNTs modified GCE. Poly provided the polymer matrices to maintain the sensing activity and served as a redox mediator for enzymatic glucose oxidation. This biosensor showed enhanced current response at low potential and therefore common interferences from AA, UA, and acetaminophen could be avoided. Zhu and coworkers IC-87114 suggested a Prussian Blue based amperometric glucose biosensor by assembling the PB nanoparticles on the surface of MWCNTs modified GCE followed by immobilization of GOx. It showed good sensitivity, fast response with a detection limit of 12.7 mM. Similar PB based glucose biosensors were also prepared by immobilizing GOx in a film of LBL assembly of CS and MWCNTs and on the nanocomposite film of PB nanoparticles/MWCNTs/poly. Manesh et al.
fabricated a glucose biosensor based on the immobilization of GOx into an electrospun composite membrane consisting of polymethylmethacrylate dispersed with MWCNTs wrapped by a cationic PDDA polymer. This nanofibrous electrode exhibited excellent electrocatalytic activity towards H2O2 with a pronounced oxidation current at 100 mV. Glucose was detected amperometrically BMY 7378 with this nanofibrous electrode with a detection limit of 1 M. A highly sensitive and selective glucose biosensor based on immobilization of GOx within mesoporous CNTstitania Nafion composite film coated on a platinized GCE, was also developed recently by Lee and coworkers. It responded linearly to glucose in the wide range from 50 ?M to 5.0 mM with sensitivity of 154 mA M 1cm 2.
A mediatorless glucose biosensor, based on the incorporation of GOx to the composite electrode of colloidal gold CNTs Teflon showed a remarkably higher sensitivity than that achieved with other GOx CNTs bioelectrodes. It could be used for ethanol biosensor by incorporating alcohol dehydrogenase. Chu et al. developed an amperometric glucose biosensor based on adsorption of GOx at the gold and platinum nanoparticles modified CNTs electrode where CNTs were covalently immobilized on cysteamine modified gold electrode. The GOx/Au nano/Pt nano/CNTs/Au electrode was then covered with a thin layer of Nafion to avoid the loss of GOx and suppress the interfering signals from UA and AA. Recently, Zou et al. developed an amperometric glucose biosensor based on electrodeposition of platinum nanoparticles onto MWCNTs and entrapping an enzyme in CS SiO2 sol gel.
This electrode showed an excellent electrocatalytic activity and high stability as well due to the synergistic action of Pt and MWCNTs and the biocompatibility of CS SiO2 sol gel. A wide linear range from 1 M to 23 mM and a low detection limit of 1 M was achieved for glucose sensing. Zhao et al. recently investigated an amperometric glucose biosensor based on PtNPs combined aligned CNTs electrode. The combination of PtNPs and CNTs in this glucose biosensor showed a highly sensitive detection of glucose. Kang et al. constructed another glucose biosensor based on the integration of CNTs with gold platinum alloy nanoparticles. In this sensor, GOx was immobilized in biocompatible CS through cross linking with GA on the Au PtNPs/CNTs/CS film.

Recent investigations reveal that A. sativum impairs the activity of the liver enzymes that process ABT-751 protease inhibitors and raises the protease inhibitor levels. The in vitro antiviral activity of A. sativum extract on human cytomegalovirus was also evaluated in tissue cultures, plaque reduction, and early antigen assay. A dose dependent inhibitory effect of GE was evident when GE was applied simultaneously with HCMV. The in vitro antiviral effect of garlic against parainfluenza virus type 3 and human Rhinovirus type 2 has also been evaluated. 5.1.4. Cocos nucifera. The coconut belongs to the Family Arecaceae. The most common form of its usage is the coconut oil, which is extracted from the kernel of matured coconut. Throughout the tropical regions, it has been the primary source of fat in the diets of millions of people since aeons.
Cocos nucifera oil has a long history of use, both as food and as medicine, throughout the world. It holds a high place of respect in Ayurvedic medicine in India. In folk remedies around the world, coconut is used to treat a wide assortment of ailments including abscesses, alopecia, amenorrhea, asthma, blenorrhagia, Ki16425 bronchitis, bruises, burns, cachexia, calculus, colds, constipation, cough, debility, dropsy, dysentery, dysmenorrhea, earache, erysipelas, fever, flu, gingivitis, gonorrhea, hematemesis, hemoptysis, jaundice, menorrhagia, nausea, phthisis, pregnancy, rash, scabies, scurvy, sore throat, stomachache, swelling, syphilis, toothache, tuberculosis, tumors, typhoid, venereal diseases, and wounds. It has been reported that certain fatty acids, primarily medium chain fatty acids, and their derivatives have potent antiviral properties.
When C. nucifera oil is consumed, the mediumchain triglycerides are broken down into individual medium chain fatty acids and monoglycerides, which can kill or inactivate pathogenic microorganisms inside the body. The antiviral action, attributed to monolaurin, is that of solubilizing the lipids and phospholipids in the envelope of the pathogenic organisms causing the disintegration of their outer membrane. There is also evidence that MCFA interfere with the organism,s signal transduction and the antimicrobial effect in viruses is due to interference with virus assembly and viral maturation. 5.1.5. Zingiber officinale. Zingiber officinale is a plant which belongs to the family Zingiberaceae.
The characteristic odor and flavor of ginger root is caused by a mixture of zingerone, shogaols, and gingerols, volatile oils that comprise of about one to three percent of the weight of fresh ginger. In laboratory animals, the gingerols increase the motility of the gastrointestinal tract and have analgesic, sedative, antipyretic, and antibacterial properties. Ginger contains gingerol, a pungent ingredient of ginger volatile oil with sulphur containing compounds, and enzymes. The antibiotic properties of allicin are well known. The allicins have fibrinolytic activity, which reduces platelet aggregation by inhibiting prostaglandin E2. Compounds in ginger also increase levels of antioxidant enzymes, including superoxide dismutase and glutathione peroxidase, which may be beneficial in inflammatory reactions triggered by viral infections. Anti influenza agents have been isolated from Z. officinale.
