Effects of saponins from Panax notoginseng on ADP-induced rat platelet aggregation. (A) Saponins showed either platelet- or anti-platelet aggregatory effect. All the saponins were used at 200 μM. Aspirin (5 mM) served as a positive control to determine the effectiveness of the reaction. (B) Dose–response curve for notoginsenoside Ft1 on rat platelet aggregation rate in vitro (EC50 = 56.42 μM). (Compared with control, *P < 0.05, ***P < 0.001, n = 6, mean ± SD).
