摘要
采用正反相硅胶、MCI树脂、Sephadex LH-20和Rp-HPLC等色谱手段进行蒿状大戟Euphorbia dracunculoides化学成分的分离纯化,从蒿状大戟地上部分的70%丙酮提取物中得到16个化合物。利用MS、^1H NMR和^13C NMR等现代波谱技术确定化合物结构为西瑞香素(daphnoretin, 1),异秦皮素(isofraxidin,2),东莨菪内酯(scopoletin, 3),山柰酚(kaempferol,4),槲皮素(quercetin,5),番石榴苷(guaijaverin,6),紫云英苷(astragalin,7),槲皮素-3-O-β-D-吡喃葡萄糖苷(quercetin-3-O-β-D-glucopyranoside, 8),柚皮素-7-O-β-D-吡喃葡萄糖苷(naringenin-7-O-β-D-glucopyranoside,9),5-甲氧基芹菜素-7-O-β-D-吡喃葡萄糖苷(5-O-methyl-apigenin-7-O-β-D-glucopyranoside,10),没食子酸甲酯(methyl gallate, 11),prionitiside A(12),(2S)-2,3-dihydroxypropyl-1,6,8-trihydroxy-3-methyl-9,10-dioxoanthracene-2-carboxylate(13),3,3'-O-二甲基鞣花酸(3,3'-di-O-methyl ellagic acid, 14),3'-O-methyl-3,4-O,O-metheneellagic acid-4'-O-β-D-glucopyranoside(15)和3,4-methylenedioxy-3'-O-methylellagic acid(16)。其中,化合物 1~3,6~9,11和14为首次从该植物中分离得到,化合物10,12,13,15和16首次从大戟属植物中分离得到。
Sixteen compounds including daphnoretin (1), isofraxidin (2), scopoletin (3), kaempferol (4), quercetin (5), guaijaverin (6), astragalin (7), quercetin-3-O-β-D-glucopyranoside (8), naringenin-7-O-β-D-glucopyranoside (9), 5-O-methylapigenin-7-O-β-D-glucopyranoside (10), methyl gallate (11), prionitiside A (12), (2S)-2,3-dihydroxypropyl-1,6,8-trihydroxy-3-methyl-9,10- dioxoanthracene-2-carboxylate (13), 3,3'-di-O-methyl ellagic acid (14), 3'-O-methyl-3,4-O,O-metheneellagic acid-4'-O-β-D- glucopyranoside (15) and 3,4-methylenedioxy-3'-O-methylellagic acid (16), were isolated from the 70% acetone extract of Euphorbia dracunculoides Lam. Among them, compounds 1-3, 6-9, 11, and 14 were isolated from E. dracunculoides for the first time, and compounds 10, 12, 13, 15, and 16 were firstly obtained from the genus Euphorbia. Their structures were elucidated by spectroscopic analysis, including ^1H-NMR, ^13C-NMR, and ESI-MS.
