Abstract

Two flavonol O-glycosides identified as the 3-O-alpha-arabinopyranosyl(1'"-->6")-beta-glucopyranoside 7-O-beta-glucopyrano sides of kaempferol and quercetin were isolated from the whole plant of Corydalis bungeana Turcz. together with eight known flavonol O-glycosides. Two isoquinolinone alkaloids were also obtained from the same source, including the new derivative, 6,7-methylenedioxy-2-(6-acetyl-2,3-methylenedioxybenzyl)- 1(2H)-isoquinolinone. The structures were determined by spectroscopic methods (NMR and high-resolution MS). (C) 2004 Elsevier Ltd. All rights reserved.
