摘要
目的: 对黄秋葵石油醚部位的化学成分进行分离和鉴定。 方法 :采用硅胶柱色谱、重结晶等方法分离纯化,并根据理化性质和波谱分析鉴定化合物的结构。 结果 :从黄秋葵石油醚部位分离得到14个化合物,分别为6-羟基豆甾-4-烯-3-酮( 1 ),6β-羟基豆甾-4,22-二烯-3-酮( 2 ),3β-羟基豆甾-5-烯-7-酮( 3 ),3β-羟基豆甾-5,22-二烯-7-酮( 4 ),豆甾-5-烯-3β,7β-二醇( 5 ),豆甾-5,22-二烯-3β,7β-二醇( 6 ),豆甾-4,22-二烯-3,6-二酮( 7 ),豆甾-4,22-二烯-3-酮( 8 ),麦角甾-7,22-二烯-3β-醇( 9 ),环阿尔廷-25-烯-3,24-二醇( 10 ),羽扇豆醇( 11 ),橙酰胺乙酸酯( 12 ),豆甾醇( 13 ),棕榈酸( 14 )。 结论 :化合物 1~12 均为首次从该植物中得到,也为首次从本属植物中分离得到。
Objective : To study the chemical constituents of Abelmoschus esculentus. Method : The chemical constituents were isolated and purified by chromatography on silica gel and recrystallization. The chemical structures were elucidated on the basis of physicochemical properties and spectral data. Result : Fourteen compounds were isolated and identified as 6-hydroxy-stigmasta-4-en-3-one( 1 ), 6-hydroxy-stigmasta-4,22-dien-3-one( 2 ), stigmasta-5-en-3-ol-7-one( 3 ), stigmasta-5,22-dien-3-ol-7-one( 4 ), stigmast-5-en- 3, 7-diol( 5 ), stigmast-5,22-dien-3,7-diol( 6 ), stigmast-4,22-dien-3,6-dione( 7 ), stigmasta-4,22-dien-3-one( 8 ), ergosta-7,22-dien-3-ol( 9 ), cycloart-25-en-3,24-diol( 10 ), lupeol( 11 ), aurantiamide acetate( 12 ), stigmasterol( 13 ), hexadecanoic acid( 14 ). Conclusion : Compounds 1-12 are obtained from the genus Abelmoschus plant for the first time and also from the Malvaceae for the first time.
