Study on the Quality Standardfor Erdingerxian Mixture / 中国药师

ABSTRACT

Objective:To establish the quality standard for Erdingerxian mixture. Methods:Herba Violae and Cortex Phellodendri in Erdingerxian mixture were identified by TLC. Icariin and curculigoside were determined by HPLC. Results:The characteristic iden-tification by TLC was distinct and highly specific. The linear range of icariin was 5.77-184.50μg·ml-1(r=0.999 9),and the aver-age recovery was 96.55%(RSD=1.14%,n=9). The linear range of curculigoside was 12.36-395.50 μg·ml-1(r=1.000 0),and the average recovery was 100.58%(RSD=2.92%,n=9).Conclusion: The method is reliable, accurate, sensitive and specific, which can be used for the quality control of Erdingerxian mixture.
