仙茅化学成分的研究

为研究仙茅(Curculigo orchioides Gaertn)根茎中的化学成分,采用硅胶柱色谱、C_(18)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.

Chemical constituents from Curculigo orchioides

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.
