ABSTRACT
To evaluate the effect of different fractions of Taohong Siwu decoction on ADP-induced platelet aggregation and thrombin activity, and to exploit the bioactive constituents, ADP-induced platelet aggregation rate in rabbits was determined by using the method of turbidity method. A bioassay called thrombin time was developed for determining anti-thrombin activities. UHPLC-Q-TOF-MS method was used to qualitatively analyze the chemical constituents of different parts. Alcohol precipitation deposition fraction, alcohol precipitation supernatant fraction and 20% to 30% alcohol elution fraction could significantly inhibit ADP-induced platelet aggregation. Alcohol precipitation supernatant fraction, water insoluble fraction and 40% to 70% alcohol elution fraction could significantly inhibit thrombin activity. The main components of alcohol precipitation deposition fraction, alcohol precipitation supernatant fraction and 20% to 40% alcohol elution fraction were analyzed and identified as aromatic acids, glycosides and phthalides. The bioactive constituents of Taohong Siwu decoction for inhibiting ADP-induced platelet aggregation and thrombin activity include aromatic acids, glycosides and phthalides. This experiment provides scientific basis to further explore the bioactive constituents and mechanism of Taohong Siwu decoction in treating blood stasis syndrome.
