棕榈花蕾化学成分研究

Studies on Chemical Constituents from Bud of Trachycarpus fortunei

摘要:

目的: 研究棕榈花蕾的化学成分。 方法: 采用大孔吸附树脂色谱、硅胶色谱、凝胶渗透色谱等方法进行分离纯化,利用理化检验和波谱分析进行化合物结构鉴定。 结果: 从棕榈花蕾中分离了8个化合物,鉴定其中6个化合物的结构,分别为异香草酸(isovanillic acid,Ⅰ)、β-谷甾醇(β-sitosterol,Ⅱ)、薯蓣皂苷(dioscin,Ⅲ)、5-咖啡酰氧基莽草酸(5-O-caffeoylshikimic acid,Ⅳ)、咖啡酸(caffeic acid,Ⅴ)、芦丁(rutin,Ⅵ)。 结论: 化合物Ⅰ,Ⅱ,Ⅳ~Ⅵ为首次该植物中分离得到。Ⅰ,Ⅳ为首次从棕榈属植物中分离得到。

Abstract:

Objective: To study the chemical constituents from the bud of Trachycarpus fortunei. Method: The constituents were isolated and purified by using macroporous resin column chromatography, silica gel column chromatography and Sephadex LH-20 chromatography, their structures were identified by physicochemical properties and spectrum analysis. Result: Eight compounds were separated and six of them were isolated and identified as isovanillic acid (Ⅰ), β-sitosterol (Ⅱ), dioscin (Ⅲ), 5-O-caffeoylshikimic acid (Ⅳ), caffeic acid (Ⅴ), rutin (Ⅵ). Conclusion: Compounds Ⅰ, Ⅱ, Ⅳ, Ⅴ and Ⅵ are firstly obtained from T. fortune, compounds Ⅰ and Ⅳ are firstly obtained from the plant of Trachycarpus.
