木棉树皮的化学成分

Chemical constituents of the stem bark of Bombax ceiba L.

摘要: 采用硅胶、凝胶等柱色谱方法对木棉Bombax ceiba L.干燥树皮的化学成分进行分离纯化，通过NMR，MS等波谱技术鉴定化合物结构，分离鉴定了13个化合物，分别为:羽扇豆醇( 1 )，羽扇豆酮( 2 )，白桦脂酸( 3 )，泽屋萜( 4 )，齐墩果酸( 5 )，3-oxooleanolic acid( 6 )，cleomiscosin A( 7 )，(±)-lyoniresinol( 8 )，链甾醇( 9 )，豆甾-3，6-双酮( 10 )，(+)-lasiodiploidin( 11 )，aurantiamide acetate( 12 )，(2S，3S，4R，10E)-2-［(2R)-2-hydroxytetracosanoylamino］-10-octadecene-1，3，4-triol( 13 )。其中 3 ， 4 ， 6 ， 7 ~ 13 均为首次从该植物中分离得到。

Abstract: Thirteen compounds were isolated from the stem bark of Bombax ceiba L. by silica gel, and Sephadex LH-20 column chromatography. Their structures were identified by spectroscopic analysis as: lupeol( 1 ), lupeone( 2 ), betulinic acid( 3 ), zeorin( 4 ), oleanolic acid( 5 ), 3-oxooleanolic acid( 6 ), cleomiscosin A( 7 ), (±)-lyoniresinol( 8 ), desmosterol( 9 ), stigma-3, 6-dione( 10 ), (+)-lasiodiploidin( 11 ), aurantiamide acetate( 12 ), and(2S, 3S, 4R, 10E)-2-［(2R)-2-hydroxytetracosanoylamino］-10-octadecene-1, 3, 4-triol( 13 ). Among them, compounds 3 , 4 , 6 , 7 - 13 were isolated from this plant for the first time.
