Abstract

Investigation of the n-BuOH extract of the roots of Rumex nepalensis afforded two new seco-anthraquinone glucosides, nepalensides A (1) and B (2), along with nine known compounds, torachrysone (3), rumexoside (4), orientaloside (5), orcinol glucoside (6), aloesin (7), lyoniresinol 3α-O-β-D-glucopyranoside (8), (−)-epicatechin-3-O-gallate (9), (3,5-dimethoxy-4-hydroxyphenol)-1-O-β-D-(6-O-galloyl) glucose (10), and (−)-epicatechin (11). Their structures were elucidated on the basis of spectroscopic methods. The possible formation of nepalensides A and B is briefly discussed.

Key words

Rumex nepalensis - Polygonaceae - seco‐anthraquinone glucosides
