采用多种色谱手段从羊蹄类中药巴天酸模(Rumex patientia L.)乙酸乙酯部位分到12个化合物,波谱学方法鉴定了它们的结构,分别为2,4-二羟基-3,6-二甲基苯甲酸乙酯(1),1-(2,4-Dihydroxy-6-methyl phenyl)acetophenone(2),大黄素(3),大黄酚(4),槲皮苷(5),Imperanene(6),2,3-Dihydro-2-(4-hydroxy-3,5-dime-thoxyphenyl)-3-hydroxymethyl-5-(2-formylvinyl)-7-methoxybenzofuran(7),4-酮松脂酚(8),(+)-Lyoniresinol 3α-O-β-D-glucopyranoside(9),乌苏酸(10),5-烯-7α-羟基谷甾醇(11)和卢.谷甾醇(12)。其中化合物1,2,5-11均为首次从该中药中分离得到。
Twelve compounds were isolated from the aerial parts of Rumex patientia. Their structures were identified as Methyl 2,4-dihydmxy-3,6-dimethylbenzoate ( 1 ), 1 -( 2,4-Dihydroxy-6-methyl phenyl ) -acetophenone ( 2 ), Emodin (3), Chrysophanol ( 4 ), Quercitrin ( 5 ), Imperanene ( 6 ), 2, 3-Dihydm-2-( 4-hydroxy-3,5-dimethoxyphenyl ) -3- hydroxymethyl-5-(2-formylvinyl)-7-methoxyhenzofumn (7) ,4-Ketopinoresinol (8) , ( + )-Lyoniresinol 3a-O-β-D-glu- copyranoside (9), Ursolic acid (10), 5-en-7α-Hydroxysitosterol ( 11 ), andβ-stiosterol ( 12 ), respectively, by spectroscopic methods. Among these, compounds 1,2,5-11 were isolated from this plant for the first time.
