【摘要】 利用ＴｏｙｏｐｅａｒｌＨＷ－４０（Ｃ）凝胶反复柱层析，从落新妇（Ａｓｔｉｌｂｅｃｈｉｎｅｎｓｉｓ）全草的７０％Ｍｅ２ＣＯ提取物中分离得到４种丹定类化合物，经过化学及核磁共振分析分别确定其结构为３－Ｏ－没食子酰基－（－）－麦儿茶素［３－Ｏ－ｇａｌｌｏｙｌ－（－）－ｅｐｉｃａｔｅｃｈｉｎ］ＡＣ－１，３－ｏ－没食子酰基－表儿茶素－（４β－８）－（３－Ｏ－没食子酰基）－表儿茶素［（３－Ｏ－ｇａｌｌｏｙｌ）－ｅｐｉｃａｔｅｃｈｉｎ－（４β－８）－（３－Ｏ－ｇａｌｌｏｙｌ）－ｅｐｉｃａｔｅｃｅｃｈｉｎ］ＡＣ－２，２；１，２，４，６－四－Ｏ－没食子酰基－β－Ｏ－葡萄糖［１，２，４，６－ｔｅｔｒａ－Ｏ－ｇａｌｌｏｙｌ－β－Ｏ－ｇｌｕｃｏｓｅ］ＡＣ－３，３和没食子甲酯（ｍｅｔｈｙｌｇａｌｌａｔｅ）ＡＣ－４，４．这些成分均为首次从该植物中得到。更多还原

【Abstract】 Four tannin compounds are isolated from herb extract of 70% etoh of astilbechinensis by column chromatography of toyopeal HW-40. the identificated with the chemical method and spectral means of’ H-NMR the fracture of fourtannins identi fied respectlvely as s [3-o-galloyl- (-) -epicateChin]AC-1; [(3-o-galloyl)-epicatechin- (4β-8)- (3-o-galloyl)-epicatechin]Ac-2; [1, 2. 4. 6-tetra-o-galloyl-β-D-glucose] AC-3; [methyl gallate]AC-4. These compounds hare first been foundin astilbe chinensis.更多还原
