Figure 3

Effect of 6 (100 μM) on acetylcholine-induced vasodilation in endothelium-intact rat aortic rings. Control: rings incubated with vehicle only (DMSO) (straight line, □); rings incubated with 6 (straight line, ○); rings incubated with 500 μM pyrogallol (straight line, ■); rings incubated with 6 and 500 μM pyrogallol (straight line, ●); rings incubated with catechin (10 mM) and 500 μM pyrogallol (dotted line, ∆). Statistical analyses were made using Student’s t-test for unpaired data. ** p < 0.01 vs. the pyrogallol group.
