- Abstract
A new chromone glucoside 2,5-dimethyl-7-hydroxychromone-7-O-β-glucopyranoside (1), was isolated from the 75% EtOH extract of the roots of Rumex gmelini Turcz., together with five known compounds, nepodin-8-O-β-D-glucopyranoside (2), 10-hydroxyaloin A (3). 10-hydroxyaloin B (4) ,5-methoxyl-1 (3H) -benzofuranone-7-O-β-D-glucopyranoside (5), phenylethyl-O-α-L-arabinopyranosy- (1→6) -O-β-D-glucopyranoside (6), Their structures were elucidated mainly based on NMR (HSQC, HMBC and H-HCOSY) and MS spectral data.
