【Abstract】 Objective: To study the chemical constituents in seeds of Taxus mairei. Method: Preparative HPLC, TLC and spectro-scopic analyses were used to isolate and elucidate the chemical constituets in the plant. Result: Seven taxane diterpenoids were isolated from the seeds of T. mairei and identified as taxinine A(1) , 9-deacetyltaxinine(2) , 9-deacetyltaxinine E(3) , 2-deacetyltaxinine(4) , taxezopidine G(5) , 2-deacetoxytaxinine J(6) , 2-deacetoxytaxuspine C(7) . Conclusion: Except Compounds 5,6, all the compounds were obtained from seeds of this plant for the first time.更多还原
