Relaxant effect of (A) hibiscus sabdariffa calyces crude extract (10-4 to 10-1g/l) and (B) acetylcholine or sodium nitroprusside (10-9 to 3.10-6 M) in aortic rings with and without endothelium precontracted with norepinephrine (10-8 to 10-6M). Values are expressed as mean ± SEM of 9-12 experiments; ns: not significant; * P < 0.05; ** P < 0.01, ANOVA.
