Hastatusides A and B: Two New Phenolic Glucosides from <i>Rumex hastatus</i>

Abstract

Abstract magnified image Two new compounds, hastatusides A and B ( 1 and 2 , resp.), together with five known compounds, resveratrol, rumexoside, torachrysone‐8‐yl β ‐ D ‐glucopyranoside, rutin, nepodin, and orientaloside were isolated from the roots of Rumex hastatus. Their structures were determined by spectroscopic methods, including 1D‐ and 2D‐NMR spectroscopy.
