Evaluation method of medicine nature of individual ginsenosides / 中国药理学通报

ABSTRACT

.Aim To establish the evaluation methods of the med¬icine nature of ginsenosides by eorrelation analysis between med¬icine nature and ginsenoside contents in five Panax herbs with different medicine nature and the measurement of their effects on Na + /K + -ATPase activities.Methods 'Hie contents of ginsen¬osides in Sanqi, red ginseng , ginseng , American ginseng and ginseng leaves in the existing literature were eolleeted.and the medicinal nature was assigned by vector methods.rI1ie medicine nature of ginsenosides and the contribution of ginsenoside to the medicine nature were evaluated through bivariate correlation a- nalysis and grey eorrelation degree respectively.'Hie effects of ginsenosides on the Na+ /K +-ATPase activities of L02 eells and in pig eerebral cortex were measured to evaluate the medicine na¬ture of ginsenosides.Results Correlation results indicated that the order of correlation coefficients of ginsenosides to the warm and hot medicine nature was Rf > R1 > Rg3 > Rg2 > Rbl > Ro, while the order of correlation coefficients of ginsenosides to the eool and eold medicine nature was Rb2 > Re > Rd > Fll.Grey eorrelation degree analysis showed that the contribution of ginsen¬oside to the medicine nature was F11 > Re > Kg2 > Rd > Rb2 >Rbl > Rgl > Rc > Rg3 > R1 > Rf > Ro.The effects of ginsen- osides on Na +/K +-ATPase activities showed that the substance basis of the warm medicine nature was ginsenoside Rbl, Rb3, Rc, Rf, Rg2, Rgl, Rhl, Rg3, R1 and Ro, which increased the activity of Na + /K + -ATPase.While the cold and cool medi- cine nature were ginsenoside Rh2, Rd, Rh2, Re and oleanolic acid, which inhibited the activity of Na+/K
