摘要
从土茯苓根茎中分出3个二氢黄酮醇甙,经理化常数和波谱分析,鉴定为异黄杞甙,异落新妇甙,落新妇甙。利用二维核磁共振相关谱对其信号进行了全面归属,并首次确定了甙键构型。
hree flavanonol glucosides have been isolated from the rhizome of Smilax glabra. Their structures were identified as isoengetitin,isoastilbin and astilbin on the basis of their physicochemical and spectral data.Full assignment of their 1HNMR and 13 CNMR chemical shift signals was established by various 2D NMR techniques.Their glucosidic bond structures were determined for the first time.Isoastilbin was isolated from Smilax for the first time.
