摘要
为研究仙茅(Curculigo orchioides Gaertn)根茎中的化学成分,采用硅胶柱色谱、C18中压柱色谱、高压制备色谱对仙茅根茎甲醇提取物的正丁醇部位进行分离纯化,根据化合物的波谱数据鉴定其结构.从中分离得到10个化合物,分别鉴定为2, 6-二甲氧基苯甲酸(1)、咖啡酸(2)、原儿茶酸(3)、orchioside B (4)、curculigoside C(5)、orchioside E(6)、丁香酸(7)、hemsleyanumoide(8)、丁香酸葡萄糖苷(9)、绿原酸(10).其中,化合物6为1种新的酚苷类物质,命名为orchioside E,化合物2、8首次在仙茅中分离得到.
To study the chemical constituents in Curculigo orchioides Gaertn rhizomes, silica gel column chromatographies, C18 medium-pressure column chromatographies and high pressure preparative liquid chromatography system were used to isolate and purify the n-butanol portion of MeOH extract from the rhizomes of Curculigo orchioides. The structures were identified based on spectroscopic data. Ten compounds were isolated and identified as 2,6-dimethoxybenzoic acid(1), caffeic acid(2), protocatechuic acid(3), orchioside B(4), curculigoside C(5), orchioside E(6), syringic acid(7), hemsleyanumoide(8), glucosyringic acid(9), chlorogenic acid(10). Among them, compound 6 is a new phenolic glucoside named orchioside E, compound 2 and 8 are isolated from the Curculigo orchioides for the first time.
