OBJECTIVE
To study the chemical constituents in seeds of Taxus mairei.
METHODS
Preparative HPLC, TLC and spectroscopic analyses were used to isolate and elucidate the chemical constituets in the plant.
RESULTS
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).
CONCLUSIONS
Except compounds 5,6, all the compounds were obtained from seeds of this plant for the first time.
