Inhibitory effect of PTS and its main ginsenosides on human platelet aggregation. a Human platelets (4 × 108 cells · ml-1) were pre-incubated with or without PTS and then stimulated with collagen (2.5 μg · ml-1), thrombin (0.1 U · ml-1) or ADP (10 μM). The platelet aggregation rate was determined. b Human platelets (4 × 108 cells · ml-1) were pre-incubated with or without Rg1, Re, R1, and then stimulated with ADP (10 μM). The platelet aggregation rate was determined. Bar graphs show mean ± SD of at least 3 independent experiments performed. *p < 0.05, **p < 0.01 vs. agonist activated control
