Evaluation of the Bronchorelaxant, Genotoxic, and Antigenotoxic Effects of Cassia alata L.
Figure 1
(a) Typical tracing showing the relaxant effect of CF-AECal on acetylcholine (ACh, 10−5 M) induced contractions in isolated rat trachea preparation. (b) Relaxing concentration-response curves of crude aqueous-ethanol extract (▲), chloroformic (■), ethyl-acetate (⚫), and n-butanol () fractions of crude extract from Cassia alata on mouse tracheal rings precontracted with acetylcholine. Ordinate scale: percentage reduction in responses to ACh 10−5 M as appropriate. Each point is the mean derived from at least 6 experiments; vertical lines show sample SEM means values.
