Quantitative Analysis of Astragloside IV.
Objective:To develop a method to determine Astragaloside IV in spray-dry of Rad ix Astragali by HPLC-ELSD.
Methods:ELSD was used to determine directly Astragaloside IV in sp ray-dry of Radix Astragali on Elite-OSD column, using CH3CN-H 20(36:64) as a mobile phase. The flow rate was 1.0 ml/min. The temperature of drift tube for ELSD was 105 Deg C and the flow rate of N2 was 2.84 ml/min.
Results:The recovery of the added sample was 91.68% and RSD 1.6 4 %. Soluble amylum was helpful for spray-dry but it can influence was determinat ion of Astragaloside IV.
Conclusion:The method is accurate and can be used in the determination of Astragaloside IV in spray-dry of Radix Astragali. Better adjuvant should be found.
