Abstract:Objective: To study the chemical constituents of Psoralea corylifolia. Method: Chromatographic methods were used to separate compounds, and spectroscopic methods were used to determine the structures. Result: Five compounds were isolated and identified as furano (2″, 3″, 7, 6)-4′-hydroxyflavanone (1), psoralidin (2), genistein (3), psoralen (4), isopsoralen (5). Conclusion: Compounds 1 was a new compound named psoraleflavanone. And 13C-NMR data of compound 2 were assined for the first time.
