[Comparation of constitutions between raw Psoralea corylifolia L. and processed one].
OBJECTIVE
To study the processing material foundation of Psoralea corylfolia L. and compare the content of psoralen, isopsoralen and microelement between raw Psoralea corylifolia L. and processed one.


METHODS
The content of psoralen, isopsoralen and microelement were obtained by HPLC-gradient elution and ICP-AES.


RESULTS
The content of psoralen, isopsoralen and microelement Mn, Ca, Mg, Fe, Zn were raising, but the change of that of microelement Cu was not obvious.


CONCLUSIONS
The content of effective composition of Psoralea corylifolia L. is raised by Lei-Gong method and the biological activity is improved simultaneously.
