肿节风中黄酮苷类成分研究

目的：研究中药肿节风的化学成分，为阐明其有效成分提供依据。方法：利用聚酰胺、Sephadex LH-20，Lipophilic sephadex LH-20柱色谱进行分离，根据化合物的理化性质和波谱数据(IR，UV，MS，¹H-NMR，¹³C-NMR)鉴定其结构。结果：从肿节风水提取物中分离得到5个黄酮苷类和3个其他类化合物，分别鉴定为：山柰酚-3-O-β-D-葡萄糖醛酸苷(1)，槲皮素-3-O-α-D-葡萄糖醛酸苷(2)，槲皮素-3-O-β-D-葡萄糖醛酸甲酯(3)，5，7，4′-三羟基-8-C-β-D-葡萄糖二氢黄酮碳苷(4)，新落新妇苷(5)，5-O-咖啡酰基-奎宁酸甲酯(6)，3，4-二羟基苯甲酸(7)，异秦皮啶(8)。结论：化合物1～6为首次从本属植物中得到，其中1～3为该属中首次发现的葡萄糖醛酸类化合物。

Studies on flavonoid glycosides of Sarcandra glabra

OBJECTIVE: To in vestigate the chemical constituents of Sarcandra glabra and obtain a more comprehensive understanding on its effective components. METHOD: The constituents were isolated by various column chromatographic method and their structures were elucidated by physico-chemical properties and spectroscopic analysis. RESULT: Five flavonoid glycosides were isolated and identified as kaempferol-3-O-beta-D-glucuronide (1), quercetin-3-O-alpha-D-glucuronide (2), quercetin-3-O-beta-D-glucuronopyranoside methyl ester (3), 5, 7, 4'-trihydroxy-8-C-beta-D-glucopyranosyl flavanone (4), neoastilbin (5), 5-O-caffeoylquinic acid methyl ester (6), 3, 4-dihydroxybenzoic acid (7), isofraxidin (8). CONCLUSION: Compounds 1-6 were isolated from the genus Sarcandra for the first time. The glucuroide compounds compounds 1-3, were first isolated from the genus Sarcandra.
