ABSTRACT
OBJECTIVE:
To determine the content of glycyrrhetic acid in zhenkening capsules by RP-HPLC.METHODS:
The separation was performed on Hypersil C 18,the mobile phase consisted of methanol-water-glacial acetic acid(87∶13∶2.5)with flow rate at 1.0ml/min and detection wavelength at 254nm,the column temperature was set at room temperature.RE-SULTSThe calibration cure of glycyrrhetic acide was linear in the concentration range of 10~120?g/ml(r=0.9999),the average recovery was 99.68%(RSD=0.49%).CONCLUSION:
This method is simple,fast,accurate,and suitable for the determination of glycyrrhetic acid in zhenkening capsules.
