STUDIES ON THE STRUCTURE OF ISOASTILBIN

摘要: 从百合科菝葵属植物土茯苓(Smilaxg labra Roxb.)根茎的乙醇提取物中分得一个新的天然化合物(I),命名为异落新妇甙(isoastilbin)。根据元素分析,UV,IR,¹H-NMR,¹³C-NMR,2DNMR及FAB-MS,确定化合物I的结构为5,7,3',5'-四羟基二氢黄酮醇-3-O-α-L-鼠李糖甙。

Abstract: A new compound was isolated from Smilax glabra Roxb.,named isoastilbin,Itwas identified as 5,7,3',5'- tetrahydroxyl-flavanonol-3-O-α-L-rhamnopyranoside by means ofchemical and spectrometric analysis(UV,IR,1 H-NMR,13C-NMR,2DNMR and FAB-MS).
