泰国产攀援鱼藤的异黄酮苷成分

TWO ISOFLAVONOID GLYCOSIDES FROM DERRIS SCANDENS

摘要: 目的：对泰国产攀援鱼藤［Derris scandens (Roxb.) Benth］地上部分的化学成分进行分离、鉴定。方法：采用各种层析色谱技术进行分离。从攀援鱼藤中分离得到2个化合物，用IR，UV，MS，¹HNMR，¹³CNMR，²DNMR光谱鉴定化合物。结果：经光谱鉴定化合物结构为： 4′-甲氧基－异黄酮-7-O-［α-L-鼠李吡喃糖基(1→6)］-β-D-葡萄吡喃糖苷(I)和4′,8-二甲氧基-异黄酮-7-O-［α-L-鼠李吡喃糖基(1→6)］-β-D-葡萄吡喃糖苷(II), 分别命名为攀援鱼藤苷甲(derriscanoside A)和攀援鱼藤苷乙(derriscanoside B)。结论：化合物(I)， (II)为新的异黄酮苷类化合物。

Abstract: AIM: To investigate the chemical constituents of the aerial parts of Derris Scandens. METHODS: To isolate chemical constituent, solvent extraction together with column chromatography were used. IR, UV, MS, NMR and chemical methods were used to determine the structure of the isolated constituents. RESULTS: The structures of the two constituents obtained were elucidated as 4′-methoxy-isoflavone-7-O-［α-L-rhamnopyranosyl(1→6)］-β-D-glucopyranoside(I) and 4′,8-dimethoxy-isoflanvone-7-O-［α-L-rhamnopyranosyl(1→6)］-β-D-glucopyranoside(II) which were named derriscanoside A and derriscanoside B respectively. CONCLUSION: Compound (I) and compound (II) are two new isoflavonoid glycosides.
