a novel galacto-glycerolipid from oxalis corniculata kills entamoeba histolytica and giardia lamblia.oxalis corniculata is a naturally occurring weed that has been used in traditional medicine for the cure of dysentery and diarrhea in india. one of the common causes of dysentery is due to infection by the protist pathogen entamoeba histolytica. bioactivity profiling of extracts from o. corniculata identified several compounds that showed antiamoebic activity in axenic cultures of e. histolytica. these were characterized by nuclear magnetic resonance, infrared, and mass spectrometry as (i) oc-1, ...201020713666
antibacterial, antifungal, and insecticidal potentials of oxalis corniculata and its isolated compounds.oxalis corniculata is a common medicinal plant widely used against numerous infectious diseases. the agrochemical potential of methanolic extract, n-hexane, chloroform, ethyl acetate, and n-butanol fractions were assessed to measure the antibacterial, antifungal, and insecticidal activities of the plant. the crude, chloroform, and n-butanol soluble fractions showed excellent activities against escherichia coli, shigella dysenteriae, salmonella typhi, and bacillus subtilis but have no activity ag ...201525873973
polyunsaturated fatty acids induce polarized submembranous f-actin aggregates and kill entamoeba histolytica.we have recently identified a novel galacto-glycerolipid (ggl) from the plant oxalis corniculata that killed the human pathogen entamoeba histolytica. in this study, we show that the anti-amoebic activity of ggl was due to the polyunsaturated fatty acid α-linolenic acid (c18:3 ) side chain. treatment of α-linolenic acid to e. histolytica trophozoites disrupted the cytoskeletal network and led to polarization of f-actin at one end of the cells with prominent filopodial extensions. in addition, cl ...201323568815

distribution of endophytic bacteria in alopecurus aequalis sobol and oxalis corniculata l. from soils contaminated by polycyclic aromatic hydrocarbons.the distributions of endophytic bacteria in alopecurus aequalis sobol and oxalis corniculata l. grown in soils contaminated with different levels of polycyclic aromatic hydrocarbons (pahs) were investigated with polymerase chain reaction followed by denaturing gradient gel electrophoresis technology (pcr-dgge) and cultivation methods. twelve types of pahs, at concentrations varying from 0.16 to 180 mg·kg(-1), were observed in the roots and shoots of the two plants. the total pah concentrations i ...201324358247
analysis of vegetation in an imperata grassland of barak valley, assam.imperata grassland at dorgakona, barak valley, north eastern india was analyzed for species composition and diversity pattern in relation to traditional management practices. 19 families were in the burnt and unburnt plots of the study site with poaceae as the most dominant one. 29 species occurred in the burnt plot and 28 in the unburnt plot. most of the species were common in both the plots. the pattern of frequency diagrams indicated that the vegetation was homogeneous. imperata cylindrica, a ...201223734450
an ecological risk assessment of cry1f maize pollen impact to pale grass blue butterfly.the intrinsic toxicity of lepidopteran-active bt proteins necessitates assessment of non-target risks associated with environmental release of transgenic crops expressing these proteins. principles of ecological risk assessment provide a means for assessing non-target risks when information regarding exposure to the toxin and species-specific effects are lacking. this is shown for the case of bt cry1f maize release in japan, where off-field pollen dissemination and effect on butterfly species is ...200616827552
ethnomedicinal plants of shankaracharya hill, srinagar, j&k, india.primitive human societies have always relied on plants and plant products for various remedies. in certain areas, these folk medical prescriptions are endemic and have survived through ages from one generation to the next through word of mouth. they do not exist as written knowledge. the present study was undertaken with an objective of documenting the ethnobotanical information of medicinal plants of shankaracharya hill by taking the help of local herbalists, elderly and knowledgeable people.201526008867
ethnomedicinal plants of kathua district, j&k, india.natural products, especially those derived from plants, continue to provide new and important leads in the drug discovery process. the first step in drug discovery is to document material traditionally used to treat an ailment. documentation of such knowledge will lead to its conservation and facilitate future research on medicinal plant safety and efficacy to validate traditional use. the present study was undertaken with an aim to document the ethnomedicinal plants of kathua district.201526023030
Amelioration of CCl(4)-induced nephrotoxicity by Oxalis corniculata in rat.CCl(4) induces oxidative stress in various tissues by altering antioxidant enzymes defense system.
