摘要：

3-Oxo TE has been assumed to be involved as a biosynthetic intermediate in the epimerization of the C-3 hydroxyl group of teasterone to typhasterol. We have isolated and identified it in lily anthers by using normal-phase HPLC. Mass spectral analysis, chemical synthesis, and identification of the biotransformation product by lily cell cultures confirmed it to be 3-oxo TE. Reduction of this compound stereoselectively transformed it into typhasterol in cell cultures. It is suggested that 3-oxo TE is distributed widely in the plant kingdom as a biosynthetic intermediate from TE to TY.
