Objective To establish fat drop ning in the puerarin content determination method.Methods HPLC method was used to acetonitrile-water (9) as mobile phase,di-platisil ODS C18(250×4.6mm,5microns) chromatographic column,flow rate of 1.0ml/min,the column temperature 30℃,sample quantity 10μl,detection wavelength of 250nm. Results Ppuerarin in 0.02582~0.02582μg inside the range of sex good,r=0.9998,the recovery was 99.7%,RSD=1.1% (n=6),the negative samples without interference.3 batches of samples content were 1.93mg,0.584mg/g and 0.411mg/g.Conclusion This method is specific,accurate,simple,can be used as a fat drop ning in the method for determination of the content of puerarin.
