目的:研究桫椤Cyathea spinulosa Wall.的化学成分。方法:采用各种柱色谱进行分离纯化,根据理化性质和光谱数据进行结构鉴定。结果:从桫椤的乙醇提取物中共分离鉴定了8个化合物,分别为:豆甾-4-烯-3,6-二酮(1)、豆甾-3,6-二酮(2)、麦角甾醇(3)、原儿茶醛(4)、1-O-β-D-glucopyranosyl-(2S,3R,4E,8Z)-2-[(2-hydroxyoctade-canoyl)amido]-4,8-octadecadiene-1,3-diol(5)、(2S,3S,4R)-2-[(2’R)-2’-hydroxytetracosanoylamino]-1,3,4-octade-canetriol(6)、β-谷甾醇(7)、胡萝卜苷(8)。结论:其中,化合物1～6为首次从该植物中分离得到。
Objective: To study the chemical constituents of Cyathea spinulosa Wall. Methods: Various kinds of column chromatography were used for isolation and purification, and their structures were identified based on physicochemical properties and spectral data. Results: Eight compounds were isolated and identified from the ethanol extracts of the gall, which were stigmasterol-4-ene-3,6-dione (1), stigmasterol- (3), protocatechuic aldehyde (4), 1-O- [beta] -D- glucopyranosyl- (2S, 3R, 4E, 8Z) -2- [2-hydroxyoctade- octadecadiene-1,3-diol (5), (2S, 3S, 4R) -2 - [(2’R) -2’-hydroxytetracosanoylamino] -1,3,4-octade- canetriol Sterols (7), daucosterol (8). Conclusion: Among them, compounds 1-6 were isolated from this plant for the first time.
