Isolation and structure identification of a new isoflavone from Psoralea corylifolia

Aim To study the chemical constituents of the fruits of Psoralea corylifolia L. Methods The constituents were separated and purified by column chromatography with normal phase silica gel and polyamide. Their structures were identified on the basis of physical and spectral data (MS, NMR, HMBC and HMQC). Results Six compounds were isolated and identified as psoralen (1), isopsoralen (2), bavachalcone (3), psoralidin (4), daidzin (5) and bavadin (6). Conclusion Compound 6 is a new compound. Compound 5 was isolated from this plant for the first time.
