摘要
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 from Cyathea spinulosa. Methods：Compounds were isolated by chromato- graphic techniques. Their structures were elucidated by spectral methods. Resuhs：Eight compounds were isolated from the ethanol ex- tract of Cyathea spinulosa and identified as stigmast-4-ene-3,6-dione （ 1 ）, stigmast-3,6-dione （2）, ergosterol （3）, protocatechuic alde- hyde （4）, 1-O-β-D-glucopyranosyl- （2S, 3R,4E, 8Z） -2- [ （2-hydroxyoctadecanoyl） amido] -4,8- octadecadiene-I, 3-diol （ 5 ）, （ 2S, 3S, 4R） -2 - [ （ 2 ＇R） -2＇-hydroxytetracosanoylamino ] -1,3,4-octadecanetriol （ 6 ） ,]3-sitosterol （ 7 ）, daucosterol （ 8 ）. Conclusion： Compounds 1 -6 are isolated from this plant for the first time.
