Nitric oxide scavenging ability of ethyl acetate fraction of methanolic leaf extracts of Chromolaena odorata (Linn.)

  The nitric oxide (NO.) scavenging activities of Chromolaena odorata (Linn) King and Robinson, was investigated and compared with standard Plant Phenolic antioxidant Quercetin. Disodium pentacyanonitrosyl ferrate (2- ) dihydrate (sodium nitroprusside) was used as a nitric oxide donor. On disintegration at a physiological pH (7.2), 5 mmol/l of sodium nitroprusside generated a time dependent nitric...

Effect of administration of aqueous and ethanolic extracts of Enantia chlorantha stem bark on brewer’s yeast-induced pyresis in rats

  The phytochemical screening of aqueous and ethanolic extracts of the stem bark of Enantia chlorantha Oliv as well as the antipyretic effect of the solvent extracts at 25, 50, 100 and 200 mg/kg body weight was investigated in albino rats. Phytochemical analysis of the aqueous and ethanolic extracts of E. chloranthastem bark revealed the presence of phenolics, flavonoids, alkaloids, glycosides...
