Abstract

Objective: To study the chemical constituents from Psoralea corylifolia L. and their antitumor activities.

Methods: The constituents were isolated on silica gel column chromatography and identified by physicochemical properties and spectroscopic analysis. Morphological and MTT assays in vitro were used to explore the inhibiting effect of the active compounds on the proliferation of BGC-823 cancer cell.

Results: Two compounds were isolated from its chloroform extract and identified as psoralen (I) and isopsoralen (II). IC50 of psoralen and isoporalen were 5.82 micrograms/ml and 148.8 micrograms/ml respectively.

Conclusion: Compound I and II having antitumor activity against BGC-823 cancer cell were obtained from this plant with the yields of 0.048% and 0.11%.
