Abstract:
To study the chemical constituents of the fruits of Psoralea corylifolia L., the constituents were isolated and purified by chromatography. Two new compounds were isolated from the ethyl acetate-soluble fraction of the ethanol extract. On the basis of chemical and spectroscopic data 1D and 2D NMR, they were identified as 2-(3, 4-dihydroxyphenyl)-8, 8-dimethyl-8H-pyrano[2, 3-h]chromen-4-one (1) and 5-(2-hydroxyl-1-methyl)-ethyl-4, 5-dihydrofurano[2, 3-h](4'-hydroxyl-3', 5'-dimethoxy)-isoflavone (2), and named as coryfolia D and bavarigenin separately.
