黄秋葵乙酸乙酯部位化学成分的研究

摘要

采用硅胶柱色谱、Sephadex LH-20柱色谱、MCI、ODS和重结晶等多种分离纯化手段,对黄秋葵(Abelmoschus esculentus)乙酸乙酯部位的化学成分进行研究,从中分离得到了13个化合物,分别为β-谷甾醇(β-sitosterol) (1)β-胡萝卜苷(β-daucosterol) (2)、槲皮素(quercetin) (3)、东莨菪内酯(scopoletin) (4)、克利米可辛A(cleomiscosin A)(5)、克利米可辛C(cleomiscosin C) (6)、三十烷酸(triacontanoic acid)(7)、叶绿醇(phytol)(8)、十八碳二烯酸单甘油酯(glycerol-1-linoleate)(9)、亚油酸甘油三酯(trilinolein)(10)、熊果酸(ursolic acid) (11)、蕨内酰胺(pterolactarn) (12)、对羟基苯甲醛(p-hydroxy-benzaldehyde) (13).其中化合物4～12均为首次从黄秋葵中分离得到.%Thirteen compounds were obtained from EtoAc fraction of 95% ethanol extract of Abelmoschus esculentus L. by repeated column chromatography over silica gel.Sephadex LH-20,MCI,ODS,ete. By spectral analysis and physicochemi-cal properties,their chemical structures were identified as β-sitosterol (1) ,β-daucosterol (2) .quercetin (3) ,scopoletin (4) ,cleomiscosin A (5),cleomiscosin C (6) ,triacontanoic acid (7) , phytol (8) ,glycerol-1-linoleate (9) .trilinolein (10) ,ursolic acid (11) ,pterolactam (12) ,β-hydroxy-benzaldehyde (13). Compounds 4-12 were separated from A. esculentus for the first time.
