ABSTRACT
This study is to investigate the chemical constituents from the whole plant Corydalis edulis. The chemical constituents were separated and purified by macroporous resin D101, silica gel, Sephadex LH-20, ODS, and semi-preparative HPLC. Their structures were determined by physicochemical properties and spectroscopic data. Four compounds were isolated from the dichloromethane and water extracts of the whole plant C. edulis, and identified as 6'-β-D-xylosylicariside B2(1),(3S,5R,6S,7E)-5,6-epoxy-3-hydroxy-7-megastigmen-9-one(2), loliolide(3), and 5,5'-dimethoxybiphenyl-2,2'-diol(4), respectively. Compound 1 is a new compound, of which the absolute configuration was established by electronic circular dichroism(ECD) calculations. Compound 4 is obtained from the plants of Papaveraceae family for the first time. Compounds 2 and 3 are firstly isolated from the Corydalis genus.
