Determination of Sarsasapogenin in Jujube Seed Concentrated Pills by RP-HPLC-ELSD / 中国药房

ABSTRACT

OBJECTIVE:To determine Sarsasapogenin in Jujube seed concentrated pills by RP-HPLC-ELSD.METHODS:Separation of Sarsasapogenin was performed on Zorbax C18 column with methanol-water (9010)as a mobile phase at a flow rate of 1.0mL?min-1.The temperature of the drift tube was 85℃and the air flow-rate was at 1.71mL?min-1.RESULTS:The linear range of Sarsasapogenin was 0.112 7～0.676 2mg?mL-1(r=0.998 3).The average recovery was 99.83%(RSD=0.93%).CONCLUSION:The method is simple,accurate and reproducible,and suitable for the quality control of Jujube seed concentrated pills.
