Objective:
To study the chemical constituents of Psoralea corylifolia.
Methods:
Column chromatography was used in the isolation procedure. The structures of isolated compounds were elucidated by spectral data.
Results:
Seven compounds were isolated and their structures were identified as isopsoralen (1), psoralen (2), bavachalcone (3), 4", 5"-dehydroisopsoralidin (4), methyl 4-hydroxybenzoate (5), psoralidin (6), corylin (7).
Conclusion:
Compounds 4 and 5 are obtained from Psoralea for the first time.
