RESUMO

Purpose: Hygrophila spinosa T. Anders (Acanthaceae) is commonly used in the traditional system of medicine for the treatment of inflammation; pain; jaundice; rheumatism; arthritis; anaemia; etc. In the present study; we investigated the anti-inflammatory and antipyretic activities of the petroleum ether; chloroform; alcoholic and aqueous extracts of the leaf of this plant. Methods: The anti-inflammatory activity of the various extracts was studied based on their effects on carrageenan-induced paw oedema in rats while antipyretic activity was evaluated on the basis of their effect on Brewer's yeast-induced pyrexia in rats. The extracts were screened for alkaloids; steroids; proteins; flavonoids; saponins; mucilage; carbohydrates; organic acids; fats and oils. Results: Preliminary phytochemical screening revealed the presence of alkaloids; steroids; proteins; flavonoids; fats and oils; tannins; mucilage and organic acids in the leaves of H. spinosa. Chloroform and alcoholic extracts of leaves of H. spinosa produced significant (p 0.05 and p 0.01) anti-inflammatory and antipyretic activities in a dose-dependent manner. On the other hand; petroleum ether and aqueous extracts did not show significant anti- inflammatory and antipyretic activities. The maximum anti-inflammatory activities produced by chloroform and alcoholic extracts (400 mg/kg) were 33.7and 47.5; respectively. These two extracts also reduced elevated body temperature in rats at 200 and 400 mg/kg body weight doses throughout the observation period of 6h .Conclusion: Chloroform and alcoholic extracts of H. spinosa leaves have anti-inflammatory and antipyretic activities
