In order to isolate the active compounds in ethyl acetate fraction of Psoralea corylifolia L., activity-guided isolation was performed along with chromatographic techniques. Four active compounds were isolated from ethyl acetate fraction and identified by their NMR spectral data and physical-chemical properties. They are corylin and bavachin, which showed stimulating effect on osteoblastic proliferation and differentiation, isopsoralen and psoralen exhibited activity of promoting cell differentiation in some degree.
