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.
