Effect of (a) bergenin and (b) acetylcholine on phenylephrine (PE; 1 µM) pre-contractions in intact, denuded, pretreated; 10 µM L-NAME, 1 µM atropine, and 1 µM indomethacin on rat aortic rings. The relaxation responses, shown as means ± SEM (n = 6) where  < 0.01 and  < 0.001, represent the significance difference.
