Figure 2From: Hypotensive effect of Gentiana floribunda is mediated through Ca++ antagonism pathway Concentration-dependent relaxant effects of (A) crude extract of Gentiana floribunda (Gf.Cr) and (B) verapamil on high K + and phenylephrine (PE)-induced contractions in isolated rat aortic ring preparations. Values shown are mean ± SEM, n = 4. The K+ and PE curves in each graph are non-significantly different (p > 0.05).Back to article page
