목적:건립HPLC법측정소풍지양과립중감초산적함량。방법:Diamonsil-C18색보주(150mm×4.6mm,5μm);류동상위갑순-0.2mol/L작산안용액-빙작산(67:33:1);검측파장위250nm。결과:선성범위위44.8μg/ml~448μg/ml,평균회수솔위99.5%,RSD위1.2%(n=6)。결론:해방법간편,쾌속,준학가고。
Objective:A HPLC method was established for the determination of glycyrrhizic acid in Xiaofengzhiyang Granules. Methods:In the analysis,a Diamonsil-C18(150mm×4.6mm,5μm) column,a mobile phase of methanol-0.2mol/L ammonium acetate so-lution-Glacial acetic acid(67:33:1)and a UV wavelength of 250nm. Results:A linear range of 44.8μg/ml~448μg/ml,an average re-covery of 99.5%with RSD of 1.2%(n=6). Conclusion:The method of HPLC is simple,rapid and reliable.
