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.

为了追踪分离补骨脂乙酸乙酯萃取物中的活性成分，本实验采用多种色谱分离技术，以活性测试为导向，结合波谱技术及理化数据，从补骨脂乙酸乙酯萃取物中分离并鉴定了4个活性化合物的化学结构，它们是具有促进细胞增殖和分化作用的补骨脂异黄酮和补骨脂二氢黄酮，对细胞分化有一定促进作用的异补骨脂素和补骨脂素。
