从四川省木里县采集的云南红豆杉 Taxus yunnanensis的树皮中分得 3个紫杉烷类似物,经解析其1H,13CNMR、EIFAB MS谱及DEPT实验证明此3个类似物为1-β-hvdroxy-baccatinI(I)、 10-deacetyltaxol(Ⅱ)、 7, 9-dideacetylbaccatin Ⅵ( Ⅲ).此 3个化合物存在于红豆杉属的其它植物中,但首次从云南红豆杉中分出。

[Abstract]
Three taxane diterpenoids were isolated from the bark of Taxus yunnanensis Cheng et L.K.Fu collected in Molin county, Sichuan Province. Their chemical structures were elucidated as 1-β-hydroxy baccatin Ⅰ(Ⅰ); 10-deacetyltaxol(Ⅱ); and 7,9-dideacetyl baccatinⅥ(Ⅲ) by 1HNMR,13CNMR, EI and FABMS as well as DEPT spectrum. These compounds were isolated from T.yunnanensi Cheng et L.K.Fu for the first time even though they also existed in other species of Taxus L.
