ABSTRACT
AIM:
To develop a new quantitative analysis method for determining diosgenin in Shengmai Freeze-drying Preparation for Injection (Radix Ophiopogonis,etc.)by RP-HPLC with UV detector.METHODS:
ODS C_(18) column (5 ?m,4.6 mm?250 mm) was used with mobile phase of acetonitrile-water (88∶12).The mobile phase flow rate was 1.0 mL?min~(-1).The detection wavelength was at 204 nm.RESULTS:
The linear range of HPLC was 2.46-7.38 ?g(r=0.999 9).The average recovery was 98.3%,RSD was 0.95%(n=9).CONCLUSION:
This method is reliable,accurate and suitable for the determination of diosgenin in Shengmai Freeze-(drying) Preparation for Injection.
