Effect of Phyllostachys pubescens leaf extract (PL), Mume Fructus extract (MF), and the 2:1, 1:1, and 1:1 combinations (PM21, PM11, and PM21, respectively) from these two extracts on adenosine diphosphate (ADP)-induced rat platelet aggregation in vitro. The washed platelets from SD rats were pre-incubated at 37 °C for 5 minutes with either samples (100 μg/mL) or vehicle, and then ADP (10 μM) was added. The aggregation curves were recorded for 6 minutes. Maximum aggregation was recorded for the control (CA) and for the tests (TA). The inhibition of aggregation (IA) was calculated as: IA = (CA – TA/CA) × 100. Data are presented as mean ± SD. *p < 0.05, †p < 0.01.
