芒果叶化学成分研究 II

Chemical Constituents Study on the Leaves of Mangifera indica L.

摘要:

为探讨芒果(Mangifera indica L.)的化学成分, 从芒果叶的70%乙醇提取物中分离鉴定了13个化合物, 经波谱分析, 分别鉴定为:(-)-secoisolariciresinol-9′-O-D-glucopyranoside (1)、7S,8R-erythro-4,7,9-trihydroxy-3,3′-dimethoxy-8-O-4′-neolignan-9′-O-β-D- glucopyranoside (2)、7R,8R-threo-4,7,9-trihydroxy-3,3′-dimethoxy-8-O-4′-neolignan-9′-O-β-D-glucopyranoside (3)、(7R/S,8R)-7,8-dihydro-9′-hydroxyl-3′-methoxyl-8-hydroxymethyl-7-(4-hydroxy-3-methoxyphenyl)-1′-benzofuranpropanol 9′-O-β-D-glucopyranoside (4)、citrusin D (5)、丁香苷(6)、2,6-二甲氧基-4-羟基苯基-1-O-β-D-葡萄糖苷(7)、原儿茶酸(8)、没食子酸(9)、没食子酸甲酯(10)、没食子酸乙酯(11)、4,5-二羟基-3-甲氧基苯甲酸(12)、β-胡萝卜苷(13)。其中化合物1~7和12为首次从芒果属植物中分离得到。

Abstract:

In order to understand the chemical constituents of Mangifera indica L., 13 compounds were isolated from 75% ethanol extract of mango leaves. On the basis of NMR and MS determination, they were identified as (-)-secoisolariciresinol-9′-O-β-D-glucopyranoside (1), 7S,8R-erythro-4,7,9-trihydroxy-3,3′-dimethoxy-8-O-4′-neolignan-9′-O-β-D-glucopyranoside (2), 7R,8R-threo-4,7,9-trihydroxy-3,3′-dimethoxy-8-O-4′-neolignan-9′-O-β-D-glucopyranoside (3), (7R/S,8R)-7,8-dihydro-9′-hydroxyl-3′-methoxyl-8-hydroxymethyl-7-(4-hydroxy-3-methoxyphenyl)-1′-enzofuranpropanol 9′-O-β-D-glucopyranoside (4), citrusin D (5), syringin (6), 2,6-dimethoxy-4-hydroxyphenyl-1-O-β-D-glucopyranoside (7), protocatechuic acid (8), gallic acid (9), methyl gallate (10), ethyl gallate (11), 4,5-dihydroxy-3-methoxy benzoic acid (12), and daucosterol (13). Among them, Compounds 1-7 and 12 were obtained from Mangifera genus for the first time.
