ABSTRACT
Objective: To establish a method for determination of five saponins in Panax notginseng by HPLC and comprehensively evaluate the quality of it by using grey correlation analysis. Methods: The content of notoginsenoside R1 and ginsenoside Rg1, Re, Rb1, Rd in the different origins and commercial grades of P. notginseng was simultaneously determined by HPLC, and the entire quality evaluation model was established by grey correlation analysis. Results: The established method was applied to quantify five major bioactive components in P. notginseng simultaneously with satisfactory results. Gray correlation method can distinguish the samples from genuine producing areas, qualified samples and unqualified samples, and provide reference for quality evaluation of P. notoginseng and quality evaluation of multi-index components of Chinese materia medica. Conclusion: This HPLC method was simple, accurate, stable and rapid with better separation effect, which was suitable for determination of notoginsenoside R1 and ginsenosides Rg1, Re, Rb1, Rd; The grey recognition analysis was suitable for the comprehensive quality evaluation of multi-component samples of Chinese materia medica.
