Anti Pyretic Activity Of Aristolochia Bracteata

Abstract

Pet ether and acetone extracts of the plant Aristolochia Bracteata were prepared using Soxlet extraction. phytochemical analysis of Aristolochia Bracteata showed the presence of alkaloids, carbohydrates, flavones, triterpenoids and phytosterols in the crude extracts. In the present study, Pet.ether and acetone extracts of Aristolochia Bracteata was investigated for their anti pyretic activity. Injection of 20 ml/kg (s.c) of 20% aqueous suspension of Brewer's yeast suspension produced pyrexia in rats. Extracts at 250 mg/kg exhibited significant anti pyretic activity. Aspirin (300mg/kg) was included as standard. Pet. Ether extracts was found to be more effective than acetone extract.
