长果升麻的化学成分研究

STUDIES ON THE CHEMICAL CONSTITUENTS FROM SOULIEA VACINATA

从长果升麻(Souliea vaginata)根茎中分离出6种皂甙,经光谱(FAB-MS、~1HNMR、~1H-~1H-COSY、^(13)C-NMR、~1H-^(13)C-COSY)分析,分别鉴定为27-deoxyactein (1),actein(2),25-0-乙酰升麻醇木糖甙(3),25-甲基升麻醇木糖甙(4),升麻醉木糖甙(5),24-acetylhydroshengmanol xyloside (6),其中1为新的天然产物。

Six saponins were isolated from rhizomes of Souliea vaginata, Their structures were elucidated by spectra (FAB-MS, 1H-NMR, 1H-1H-COSY, 13C-NMR, 1H-13C-COSY) as 27-deoxyactein (1), actein (2) ,25-0-acetylcimigenol xyloside (3) , 25-0-methylcimigenol xyloside (4). cimigoside (5), 24-0-acetylhydroshengmanol xyloside (6) one of them,(1) was a new natural saponin.
