Abstract

Two flavonol glycosides: 5,7,3' -trimethoxyquercetin -3-O-β-D-fructofuranoside (1), 7,4′-O-dimethylluteolin 5-O-[α- L-arabinofuranosyl-(1→6)-β-D-glucopyranoside] (2) and one fatty acid ester (Z)-3-hydroxypentan-2-yl-10- aminooctacos-9-enoate (3) were isolated from the leaves of Aconitum carmichaeli Debx growing in Ha Giang province, Vietnam. Their structures were elucidated by spectroscopic methods, including IR, MS and NMR. This is first time these compounds were isolated from leaves of A. carmichaeli Debx.
