摘 要 ：The discovery of taxol（2）possessing clinical activities against ovarian and breast cancer has stimu－lated a wide interest in the various Taxus species.Current interest in Taxus plants focuses on needles and barks of the plant in order to obtain taxol（2）and 10—deacetylbaccatin III．Recently,we got an opportunity to investigate the constituents of hte root of Taxus yunnanensis.From the ethereal extract of the root of ti－tled plant，We solated a new compound,named taxuyunnanine(1).
