摘要:

本研究运用硅胶、C18反相、MCI柱色谱及半制备HPLC等多种色谱分离方法从酸藤子中分离得到13个化合物。通过NMR和MS数据分析, 并结合文献数据对比等方法, 鉴定了它们的结构, 包括(6R,9R)-1-Oxo-α-ionol-9-O-β-D-goucopyranoside (1), (+)-Pinoresinol (2), Leptolepisol D (3), 山柰酚(4), 山柰酚-3-α-L-鼠李糖苷 (5), Kaempferol-3-β-D-(6-O-trans-p-coumaroyl) glucopyranoside (6), Bis(2-ethylhexyl) phthalate (7), 邻苯二甲酸二丁酯 (8), 咖啡酸甲酯 (9), 芥子醛 (10), Coniferaldehyde (11), 咖啡酸 (12), 5-羟甲基糠醛 (13)。所有化合物均为首次从该植物中分离得到。

Abstract:

In the present study, we aimed to investigate the chemical constituents from Embelia laeta. The constituents were separated by various column chromatography, including silica gel, ODS gel, MCI gel, Sephadex LH-20, and semipreparative HPLC. Their structures were elucidated by spectroscopic means. A total of 13 compounds were isolated from E. laeta and identified as (6R,9R)-1-Oxo-α-ionol-9-O-β-D-goucopyranoside (1), (+)-Pinoresinol (2), Leptolepisol D (3), Kaempferol (4), Kaempferol-3-α-L-Ramnopyranoside (5), Kaempferol-3-β-D-(6-O-trans-p-coumaroyl) glucopyranoside (6), Bis(2-ethylhexyl) phthalate (7), 2-Benzenedicarboxylic diisobutyl ester (8), Caffeic acid methyl ester (9), Paldehyde (10), Coniferaldehyde (11), Caffeic acid (12) and 5-Hydroxymethyl furfural (13), respectively. All the compounds were isolated from E. laeta for the first time.
