IN-VITRO EVALUATION OF ANTIASTHMATIC ACTIVITY OF FICUS RACEMOSA L. (MORACEAE)Abstract
Asthma is a disease of the human respiratory system. The different extract of bark was obtained by successive extraction with petroleum ether, butanol, ethyl acetate and alcohol by Soxhlet. These extracts were evaluated for antiasthmatic activity by using in-vitro model, i.e., spasmolytic activity in isolated guinea pig lung strip using histamine for induction of bronchoconstriction in guinea pigs. The effect of S. extracts of the bark of the plant on isolated guinea pig lung strip was studied to know the mechanism by which the extracts exhibited muscle relaxant activity. The study showed the few extracts are effective against histamine-induced contraction. The result revealed that the antiasthmatic activity of extracts might be due to the presence of saponins and flavonoids.
