摘要:

为研究毛果巴豆枝叶中的化学成分,该文采用硅胶、Sephadex LH-20柱色谱以及HPLC等多种色谱相结合的方法,对毛果巴豆枝叶95%乙醇提取物的乙酸乙酯萃取部位进行分离,从中得到8个化合物,通过波谱数据分析并结合文献比对,将其鉴定为2β-hydroxyteucvidin acetate(1),2β-hydroxyteucvidin(2),crotoeurin B(3),山奈酚-3-O-(6″-O-顺式对香豆酰基)-β-D-吡喃葡萄糖苷(4),山奈酚-3-O-(6″-O-反式对香豆酰基)-β-D-吡喃葡萄糖苷(5),栗苷A(6),cerevisterol(7),尿嘧啶(8)。化合物2-7均为首次从该植物中分离得到。

Abstract:

To study the chemical constituents from the twigs and leaves of Croton lachynocarpus, eight compounds were isolated from 95% ethanol extract of twigs and leaves of C. lachynocarpus, by means of various chromatographic techniques including column chromatography over silica gel, Sephadex LH-20, and reversed-phase HPLC. Compounds were identified as 2β-hydroxyteucvidin acetate(1), 2β-hydroxyteucvidin(2), crotoeurin B(3), kaempferol-3-O-(6″-O-cis-p-coumaroyl)-β-D-glucopyranoside(4), kaempferol-3-O-(6″-O-trans-p-coumaroyl)-β-D-glucopyranoside(5), castanoside A(6), cerevisterol(7), uracil(8)by analyzing their spectra data and comparing with the previously reported literatures. Compounds 2-7 were obtained from the plant for the first time.
