摘要: 目的:对蓼科何首乌属植物木藤蓼(Fallopia aubertii (L. Henry) Holub)的化学成分进行分离鉴定。方法:采用各种柱色谱技术进行分离纯化,根据理化性质、波谱数据并参考相关文献解析和鉴定化合物结构。结果:分离鉴定11个化合物,分别为:色原酮(1)、槲皮素(2)、山奈酚(3)、木犀草素(4)、杨梅素(5)、杨梅素-3-O-β-D-葡萄糖苷(6)、槲皮素-3-O-L-鼠李糖苷(7)、N-反式阿魏酰酪胺(8)、p-香豆酰多巴胺(9)、β -谷甾醇(10)、胡萝卜苷(11)。结论:化合物1、5、6、9为首次从何首乌属中分离得到,除了β-谷甾醇(10),其他化合物均为首次从木藤蓼中分离得到。

Abstract: Obiective: To separate and identify chemical constituents in the stems and leaves of Fallopia aubertii (L. Henry) Holub. Methods: The dried stems and leaves of the plant were extracted repeatedly with 95% methanol for four times, and then the pooled extract was re-extracted sequentially with ethyl acetate and n-butanol. At last, the two fractions obtained were separated using various column chromatographic techniques. In addition, the structure of the separated fractions was identified and elucidated according to their physicochemical properties and spectral data as well as relevant literature data. Results: Eleven compounds were isolated and identified as 5,7-dihydroxy-2-(n-heneicosyl) chromone (1), quercetin (2), kaempferol (3), luteolin (4), myricetin (5), myricetin-3-O-β-D-glucopyranoside (6), quercetin-3-O-α-L-rhamnoside (7), N-feruloyltyramine (8), p-coumaroyldopamine (9), β-sitosterol (10) and daucosterol (11), respectively. Conclusions: It is the first time that compounds 1, 5, 6 and 9 are isolated from the genus Fallopia and all identified compounds except compound 10 from Fallopia aubertii (L. Henry) Holub.
