- W2365604796 abstract "Objective:To establish a method for the content determination of glycyrrhizic acid and liquiritin in San'ao tablets.Methods:The content of liquiritin and glycyrrhizic acid was detected by RP-HPLC.The operating conditions were Promosil C18(4.6 mm×250 mm,5 μm) column,The mobile phase consisted of acetonitrile-0.05% phosphoric acid.The detection wavelength was at 237 nm,the flow rate was 1.0 ml/min,the column temperature was 25℃,external standard method was employed.Results:The linear ranges of liquiritin and glycyrrhizic acid were obtained 0.505-5.050 μg,r= 0.999 0;0.573-5.730 μg,r=0.999 9.The average recoveries(n=9) were 98.9%(RSD=0.8%),and 97.8%(RSD=1.1%) respectively.Conclusion:The method is simple,convenient,rapid and reliable with good reproducibilty,which is appropriate to the determination accurate and reliable.Which can be used for the content determination of glycyrrhizic acid and liquiritin in San'ao tablets" @default.
