目的:研究槟榔种子的化学成分。方法:采用硅胶柱、反相RP-18柱、Sephadex LH-20柱等色谱方法进行分离纯化,根据理化性质与波谱数据鉴定化合物结构。结果:分离鉴定了13个化合物,分别为:异鼠李素(1)、槲皮素(2)、甘草素(3)、5,7,4'-trihydroxy-3',5'-dimethoxyflavanone(4)、(+)-儿茶素(5)、反式白黎芦醇(6)、阿魏酸(7)、香草酸(8)、过氧麦角甾醇(9)、豆甾-4-烯-3-酮(10)、β-谷甾醇(11)、环阿尔廷醇(12)、de-O-methyllasiodiplodin(13)。结论:其中,化合物2~4、6、7、9、10、12、13为首次从该植物中分离得到。
Objective: To investigate the chemical constituents of the fruits of Areca catechu.Methods: The chemical constituents were isolated by silica gel,RP-18 and Sephadex LH-20 column chromatographies.Their structures were determined by chemical and spectroscopic methods.Results: Thirteen compounds were isolated from the 95% ethanol extract of the fruits of Areca catechu.Their structures were identified as isorhamnetin(1),quercetin(2),liquiritigenin(3),5,7,4′-trihydroxy-3′,5′-dimethoxyflavanone(4),(+)-catechin(5),resveratrol(6),ferulic acid(7),vanillic acid(8),5,8-epidioxiergosta-6,22-dien-3β-ol(9),stigmasta-4-en-3-one(10),β-sitosterol(11),cycloartenol(12),and deO-methyllasiodiplodin(13),respectively.Conclusion: Compounds 2~4,6,7,9,10,12,13 are isolated from this plant for the first time.
