A Flavonoid from the Roots of Heracleum nepalense D. Don

Abstract

A known flavonol glycoside, namely, quercetin-3-O-β-D-glucopyranoside, was isolated from the roots of Heracleum nepalense D. Don. The structure was determined on the basis of UV, IR, FAB⁺, MS, ¹H & ¹³C NMR spectral data. The isolation is significant since a flavonoid has not been previously reported from the plant.
