Abstract:
OBJECTIVE:To study the quality standard of Changsheng oral solution.METHODS:Radix Astragali,Radix Platycodi,Spica Prunellae and Radix et Rhizoma Glycyrrhizae in the formula were identified qualitatively by TLC.The content of Liquiritin in Changsheng oral solution was determined by HPLC.The chromatographic separation was performed on Nova-Pak C18 column(150 mm?4.6 mm,4 ?m)and the mobile phase consisted of acetonitrile-2.5% acetic acid(13∶87)at a flow rate of 1.0 mL?min-1.The detective wavelength was set at 276 nm.RESULTS:Clear TLC spots were noted.The linear range of Liquiritin was 0.025 04～0.626 00 ?g(r=0.999 9).The average recovery rate of Liquiritin was 98.66%(RSD=0.52%,n=6).CONCLUSION:The established standard can be used for the quality control of Changsheng oral solution.
