珍珠荚蒾的化学成分研究

从珍珠荚蒾(Viburnum foetidum var.ceanothoides)的枝叶中分离得到14个化合物,经鉴定分别为:白桦醇(1),熊果醇(2),β-谷甾醇(3),白桦脂酸(4),熊果酸(5),对羟基苯甲酸(6),4,4′-二羟基-a-古柯间二酸(7),反式对香豆酸(8),顺式对香豆酸(9),红花菜豆酸(10),原儿茶酸(11),胡萝卜苷(12),1-O-(6-O-α-L-rhamnopyranosyl-β-D-glucopyranosyl) -4-allylbenzene(13)和apigenin 7-O-α-L-rhamnopyranosyl(1″ ′→2″)-β-D-glucopyranoside (14).其中,化合物1、7、9、10和13为首次从荚蓬属中分离得到；所有化合物均首次从珍珠荚蓬中分离得到.

Chemical Constituents from the Stems and Leaves of Viburnum foetidum var.ceanothoides

Fourteen compounds were isolated from the stems and leaves of Viburnum foetidum var.ceanothoides.Their structures were identified as betulin(1),uvaol(2),β-sitosterol(3),betulinic acid(4),ursolic acid(5),p-hydroxybenzoic acid(6),4,4′-dihydroxy-a-truxillic acid(7),E-p-coumaric acid(8),Z-p-coumaric acid(9),phaseic acid(10),protocatechuic acid(11),daucosterol(12),1-O-(6-O-α-L-rhamnopyranosyl-β-D-glucopyranosyl)-4-allylbenzene(13),and apigenin 7-O-α-L-rhamnopyranosyl(1′′′→2′′)-β-D-glucopyranoside(14).This is first report of the presence of compounds 1,7,9,10 and 13 in the genus Viburnum and 1-14 in this plant.
