Methanolic extract of Phyllanthus amarus Shum & Thonn (Euphorbiaceae) 50, 200, and 1000 mg/kg body weight significantly inhibited gastric lesions, induced by intragastric administration of absolute ethanol (8 ml/kg). Mortality, increased stomach weight, ulcer index, and intraluminal bleeding were reduced significantly by Phyllanthus amarus. Biochemical(More)
Methanolic extract of Phyllanthus amarus was tested for its anti-mutagenic activity in Salmonella typhimurium strains TA1535, TA100, and TA102 (Ames test). P. amarus extract was able to inhibit the activation and mutagenicity of 2-acetaminofluorene (2-AAF) and aflatoxinB(1) at concentrations of 0.25-2 mg/plate. It was also found to inhibit mutagenicity(More)
Chemopreventive activity of Phyllanthus amarus Schum & Thonn (Euphorbiaceae) extract was studied with regard to N-methyl N'-nitro-N-nitrosoguanidine (MNNG) induced stomach cancer in Wistar rats. Administration of the extract with MNNG significantly reduced the incidence of gastric neoplasms in rats (44%) as well as their numbers. Moreover, elevated levels(More)
Methanolic extract of P. amarus was found to have potential anti-oxidant activity as it could inhibit lipid peroxidation, and scavenge hydroxyl and superoxide radicals in vitro. The amount required for 50% inhibition of lipid peroxide formation was 104 microg/ml and the concentrations needed to scavenge hydroxyl and superoxide radicals were 117 and 19(More)
