From: Mechanisms underlying the antihypertensive properties of Urtica dioica
The graphs shows the concentration-dependent vasodilator effect of a–g crude extract of U. dioica (Ud.Cr), the Verapamil, ethyl acetate (Ud.EtAc), nHexane (Ud.nHex), chloroform (Ud.Chl), and aqueous (Ud.Aq) fractions on phenylephrine (PE) and high K+ (80 mM) precontractions, and (b–h) respectively, their effect on the Ca2+ concentration–response curves, constructed in Ca2+- free medium, in isolated rabbit aorta preparations. Values shown are mean ± SEM (n = 6–7), *p < 0.05, **p < 0.01, and ***p < 0.001, represent the significance difference between the relaxation induced by phenylephrine (PE) and high K+ (80 mM)
