酸枣根的化学成分研究(英文)

Chemical Constituents of Ziziphus jujuba Mill var. spinosa Roots

用各种柱色谱方法进行分离纯化,根据理化性质和波谱解析鉴定其化学结构,从而研究酸枣根中的化学成分。结果表明从酸枣分离得到7个化合物,分别鉴定为羽扇豆醇(Ⅰ),白桦酯酸(Ⅱ),美洲茶酸(Ⅲ),异美洲茶酸(Ⅳ),豆甾醇(Ⅴ),豆甾醇-3-O-葡萄糖苷(Ⅵ),蛇婆子碱(Ⅶ)。其中化合物Ⅳ、Ⅵ、Ⅶ为首次从该植物中得到。

Chemical constituents in the roots of Ziziphus jujuba Mill var. spinosa were studied. The consti- tuents were separated and purified by repeated column chromatagraphy with silica gel and Sephadex LH-20. Their structures were elucidated based on the chemical and spectral analysis. Seven compounds were iso-lated from petroleum,EtOA fractions. Their structures were identified as lupeol（I）, betulinic acid（H）, ceanothic acid（llI） , isoceanothic acid （IV）, stigmasterol （ V）, 3-O-/3-D-glucopyranosyl-stigmasterol＇（VI） , adouetine X （VII）. Compounds IV, VI, VII were obtained from the plant for the first time.
