The structures of two flavanonol glycosides isolated from Smilax glabra, named smitilbin and neosmitilbin, have been revised to isoastilbin and neoastilbin, respectively. The revised structures were determined based on intensive studies of chemical interconversion, NMR spectroscopy, and X-ray crystallographic analysis. The latest NMR data were also summarized.
从光叶菝葜中分离出的两种黄烷醇苷，即土茯苓苷和新土茯苓苷，其结构已分别修订为异落新妇苷和新异落新妇苷。修订后的结构是基于对化学相互转化、核磁共振光谱和X射线晶体学分析的深入研究确定的。还总结了最新的核磁共振数据。
