METHODS Fresh blood from healthy adult volunteer was collected with vacuum tube for preparation of platelet suspension. Platelet suspension was incubated with Taohong Siwu Decoction for one hour at 37℃,then centrifuged. The precipitate was washed and desorbed with buffer solutions.The differences of chemical constituents between incubated and unincubated were identified with high performance liquid chromatography-diode array detector. RESULTS According to the chromatograph at 254 nm,at least three kinds of different components were detected in Taohong siwu decoction before and after incubated with platelet. CONCLUSION Platelet suspension can be used for screening active ingredients on platelet membrane receptor from the traditional Chinese medicine.展开更多
