title: [Study on correlation between trace elements and active ingredient in glycyrrhizae radix et rhizome].
abstract: To clear the kinds of trace elements which is closely related with the active ingredient, proclaim the effects of trace elements on the quality of the Glycyrrhizae Radix et Rhizoma, provide the theoretical foundation to the further quality control of cultivation, take the advantage of the HPLC to determine the contents of glycyrrhizic acid and the liquiritin according to Chinese pharmacopoeia, use the inductively coupled plasma mass spectrometry to test the contents of Cu, Zn, Mn, Pb, Se, Cd, Ni, La, Na, Cr, M, Fe, Ca, Al, K, Sr, then, use SPSS statistical software for active ingredient and trace elements Correlation Analysis. The result of correlation analysis showed that Liquiritin contents of Glycyrrhizae Radix et Rhizoma have strong a positive correlation with the Mn, Pb contents, well, have a negative correlation with the Cu, Na contents; Glycyrrhizic acid contents showed a positive correlation with Mg, Cd, La contents, however, it showed a negative correlation with K, Fe contents. Comprehensive analysis of the results of the study, a preliminary thought that the active ingredient of Glycyrrhizae Radix et Rhizoma closely related with the trace elements, but the exact conclusion still need further study concentration-response relationship analysis.
