A new chromone glycoside from roots of Polygonum multiflorum / 中国中药杂志

ABSTRACT

Several kinds of column chromatography methods were used to investigate the chemical constituents of roots of Polygonum multiflorum. The structures of the isolated compounds were identified based on their physicochemical properties, spectral data and chemical methods. A new chromone glycoside was isolated and its structure was identified as (S)-2-(2'-hydroxypropyl)-5-methyl7-hydroxychromone-7-0-alpha-L-fucopyranosyl (1-->2)-beta-D-glucopyranoside (1).
