Fig. 2

Vasorelaxant effect of a 70 % methanol extract of Angelica dahurica root (ADE) on phenylephrine (PE)-precontracted (1 μM) rat aortic rings with (E+) (a) or without (E-) (b) endothelium. PE-induced contraction of endothelium-intact aortic ring almost relaxed to baseline after acetylcholine treatment (Ach, 10 μM) (a). PE-induced contraction of endothelium-denuded aortic ring remained unaffected after acetylcholine treatment (b). Values are expressed as mean ± SEM (n = 8) (c)
