云南红豆杉化学成分研究

Studies on The Chemical Constituents of Taxus yunnanensis Cheng et L. K. Fu.

从云南红豆杉的树皮中分离得到４个紫杉烷类二萜化合物及１个黄烷醇类化合物。根据理化常数及光谱分析确定为紫杉醇Ｃ－７－木糖甙，紫杉醇Ｂ，１０－去乙酰基巴卡亭Ⅲ，紫杉素及２Ｒ，３Ｒ－儿茶精。

Five compounds were isolated from the bark of Taxus yunnanensis. Their structures were identified onthe basis of spectral analysis and physico-chemical constants as taxol C-7-xylose, taxol B, 10-deacetyI baccatin,taxusin and 2R, 3R-catechin.
