Corydalis bungeana Turcz.
Two flavonol O-glycosides identified as the 3-O-α-arabinopyranosyl(1 → 6″)-β-glucopyranoside 7-O-β-glucopyranosides 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 whole plant of Corydalisbungeana (Papaveraceae) yielded several flavonol O-glycosides together with two isoquinolinone alkaloids.
A new alkaloid, (+)-13-epicorynoline, was isolated from the whole plant of Corydalisbungeana. Its structure was established by1H NMR, mass spectroscopy, 2D-COSY-1H NMR, UV, IR and the preparation of a derivative. The absolute configuration of the molecule was determined to be 11R,13R,14S by X-ray diffraction of its bromide salt.
