ABSTRACT
Objective:
To establish a method for determination of isofraxidin in Xiaoerkaiwei Oral Liquid (Radix Acanthopanacis Senticosi, Endothelium Corneum Gigeriae Galli, Semen Alpiniae Katsumadai, Semen Pharbitidis, etc.) by RP HPLC.Methods:
The HPLC system consisted of Symmetry C 18 column(3.9m?150mm, 5?m), methanol water (0.1% formic acid) (30∶70) mixture as a mobile phase, detection wavelength at 342nm, 0.8mL?min -1 of flow rate and column temperature at 30℃.Results:
The calibration curves of the isofraxidin were linear ( r =0.9993). The precision were perfect ( RSD =1.87). The samples were stable in 6 h. The average recovery of Xiaoerkaiwei Oral Liquid was 102.4% with RSD of 1.76%.Conclusion:
This method is simple, quick and specific, suitable for the quality control.
