ABSTRACT
AIM:
To establish an HPLC method for determing content of puerarin isoflavones in effective parts of Naomaitong Granules.METHODS:
Gradient elution with methanol-water-glacial acetic acid was used as the mobile phase.The flow rate was 1.0 mL/min,and the detection wavelength was set at 250 nm.RESULTS:
The average recoveries of puerarin,daizein-8-capiosy(1→6) glucoside,3-methoxyl-puerarin,daidzin,daidzein were 100.89%(RSD = 2.1%),100.23%(RSD = 1.06%),101.04%(RSD = 1.92%),99.82%(RSD = 2.02%),102.06%(RSD = 1.34%) respectively.CONCLUSION:
The method is simple,accurate and can be used for quality control of the effective parts in Naomaitong Granules.
