title: [Studies on chemical constituents in seeds of Taxus mairei II].
abstract: 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.
