Antiplatelet aggregation activity of diterpene alkaloids from Spiraea japonica.[Reference:
WebLink]
METHODS AND RESULTS:
Six diterpene alkaloids with an atisine-type C20-skeleton isolated from the Chinese herbal medicines Spiraea japonica var. acuta and S.japonica var. ovalifolia, as well as eight derivatives of spiramine C and Spiradine F were evaluated for the ability to inhibit aggregation of rabbit platelets induced by arachidonic acid, ADP, and platelet-activating factor (PAF) in vitro.
