摘要:

采用Sephadex LH-20、MCI gel CHP 20P、Toyopearl HW-40F和Chromatorex C18等多种柱层析和半制备高效液相色谱分离技术,对饭甑青冈叶的乙醇提取物进行分离纯化,共得到10个化合物。通过波谱数据分析并结合文献对照鉴定化合物结构分别为:没食子酸(1),没食子酸乙酯(2),脱氢双没食子酸(3),龙胆酸-5-O-β-D-葡萄糖苷(4),克列鞣质(cretanin,5),芹菜素(6),山奈酚-7-O-β-D-葡萄糖苷(7),落新妇苷(8),香橙素-7-O-β-吡喃葡萄糖苷(9),苦竹素A(10)。所有化合物均为首次从饭甑青冈植物中分离得到。

Abstract:

The ethanol extract of the leaves of Castanopsis fleuryi was isolated by Sephadex LH-20, MCI gel CHP 20P, Toyopearl HW-40F, Chromatorex C18 column chromatography and simi-preparative HPLC purification techniques to obtain ten compounds. Their structures were elucidated by spectroscopic data and comparison with literatures as:gallic acid(1), ethyl gallate(2), dehydrodigallic acid(3), gentisic acid 5-O-β-D-glucoside(4), cretanin(5), apigenin(6), kaempferol-7-O-D-glucoside(7), astilbin(8), aromadendrin7-O-glucopyranoside(9), amarusine A(10). All compounds were isolated from this plant for the first time.

Key words: Cyclobalanopsis fleuryi, chemical composition, structural identification
