Structural Revision of Two Flavanonol Glycosides from Smilax glabra

Abstract

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.

Key words

Smilax glabra (Liliaceae) - flavanonol glycoside - smitilbin - neosmitilbin - isoastilbin - neoastilbin
