Objective:To establish a HPLC-DAD method for simultaneous determination of puerarin
daidzin
liquiritin
coptisine hydrochloride
jatrorrhizine hydrochloride
baicalin
berberine hydrochloride
palmatine hydrochloride
wogonoside
baicalein
wogonin and ammonium glycyrrhizinate in Gegenqinlian decoction.Method:A Merck Chromolith RP-18e(4.6 mm × 100 mm) was used;the mobile phase was acetonitrile-0.05% phosphoric acid(contain 0.01 mol.L-1 potassium dihydrogen phosphate) in gradient elution.The detection wavelength was set at 250
275
345 nm
the flow rate was 2.0 mL.min-1 and the column temperature was maintained at 35 ℃.Result:The accuracy
precision
sensitivity
specificity and linearity of this method met the requirements.The content of the twelve active components was determined simultaneously.Conclusion:The method is rapid
simple and accurate
it has a good specificity and it can be suitable for the determination of twelve active components in Gegenqinlian decoction simultaneously.
