Figure 3From: Hypotensive effect of Gentiana floribunda is mediated through Ca++ antagonism pathway Concentration-response curves of Ca ++ in the absence and presence of different concentrations of (A) crude extract of Gentiana floribunda (Gf.Cr) and (B) verapamil in isolated rat aortic ring preparations. Values shown are mean ± SEM, n = 4. * p < 0.05, ** p < 0.01 and *** p < 0.001 compared to respective concentrations values in the Ca++ control curves.Back to article page
