Administration of 70% methanolic extract of Punicagranatum fruit rind (250 mg/kg and 500 mg/kg) shows a percentage of inhibition in 22.37, 74.21 and 21.95, 63.41 in aspirin- and ethanol-induced gastric ulceration, respectively. In treated groups of animals, the in vivo antioxidant levels such as superoxide dismutase (SOD), catalase, glutathione (GSH) and(More)
The alcoholic extract of Acanthus ilicifolius leaves inhibited the formation of oxygen derived free radicals (ODFR) in vitro with IC(50) of 550 microg/ml, 2750 microg/ml, 670 microg/ml and 600 microg/ml (Fe(2+)/ascorbate system), 980 microg/ml (Fe(3+)/ADP/ascorbate system) for superoxide radical production, hydroxyl radical generation, nitric oxide radical(More)
Alcoholic extract of Acanthus ilicifolius (250,500 mg/kg b wt) was found to be effective against tumour progression and carcinogen induced skin papilloma formation in mice. The extract was found to be cytotoxic towards lung fibroblast (L-929) cells in 72 h MTT assay and the concentration required for 50% cell death was 18 microg/ml. Oral administration of(More)
Centella asiatica (L.) Urban (Umbelliferae) is commonly used in the Ayurvedic system of medicine to treat various diseases. The present study examines the anti-tumour effect of the crude extract (CE) of Centella asiatica as well as its partially purified fractions (AF) from chromatographic procedures by both in vitro short and long term chemosensitivity and(More)
The methanolic extract of Hemidesmus indicus (L) R.Br. (Asclepiadaceae) roots was found to inhibit lipid peroxidation and scavenge hydroxyl and superoxide radicals in vitro. The amount required for 50% inhibition of lipid peroxide formation was 217.5 micro g/ml. The concentrations needed to scavenge hydroxyl and superoxide radicals were 73.5 and 287.5 micro(More)
The antiatherogenic effect of a herbal formulation, Caps HT2, was evaluated as antioxidant, anticoagulant, platelet antiaggregatory, lipoprotein lipase releasing, anti-inflammatory and hypolipidaemic activity in rats. The formulation contained the methanolic extracts of selected parts of plants, Commiphora mukul, Allium sativum, Plumbago indica, Semecarpus(More)
Antioxidant, antitumor and anticarcinogenic activity of gossypin (3,5,8,3',4'-pentahydroxy-7-O glucosyl flavone) was carried out. The compound needed for 50% inhibition of superoxide, hydroxyl and nitric oxide radicals was 3 microg/ml, 41 microg/ml and 12 microg/ml, respectively. Gossypin also impart 50% inhibition at concentrations 37 microg/ml and 43(More)
The present study evaluated the ability of methanolic extract of Centella asiatica (Linn) Urban (Umbelliferae) to induce apoptosis in different cancer cell lines. MCF-7 cells emerged as the most sensitive cell line for in vitro growth inhibitory activity. C. asiatica extract induced apoptosis in MCF-7 cells as indicated by nuclear condensation, increased(More)
Methanolic extract of Emilia sonchifolia (Compositae), a folklore medicinal plant, was found to be cytotoxic to Daltons lymphoma (DL), Ehrlich ascites carcinoma (EAC) and mouse lung fibroblast (L-929) cells, but not toxic to normal human lymphocytes, under in vitro conditions. Oral administration of the extract (100 mg/kg, b. wt) to mice reduced the(More)
The efficacy of Liposem, a polyherbal formulation, as an antioxidant and hypolipidaemic drug was evaluated in diet induced hyperlipidaemia in rats. The methanolic extract of Liposem was found to scavenge hydroxyl and superoxide free radicals, the IC50 required being 70.5 and 45.0 microg respectively. The lipid peroxidation in rat liver homogenate induced by(More)
