The effect of thirty pure compounds isolated from Chinese herbal drugs on platelet functions were screened on washed rabbit platelets. Results indicated that 1) alpinetin, fraxetin B, iso-alantolactone, γ-schisandrin, scopoletin and tetrandrine inhibited the collagen-induced rabbit platelet aggregation to more than 90% at the concentration of 100μgml; 2) fraxetin B and tetrandrine (100μgml) also strongly inhibited the arachidonic acid-induced platelet aggregation: 3) 100μgml of γ-sc-hisandrin and tetrandrine could suppress the ADP-induced aggregation: 4) at 100μgml of concentration only tetrandrine inhibited platelet aggregation induced by PAF and thrombin to 85% and 30%, respectively: 5) in addition. panaxatriol (50-100μgml) induced platelet aggregation, which had a lag time similar to that of collagen. |
