外文摘要：Objective A high performance liquid chromatographic (HPLC) method was established for the determination of glycerol in propofol medium and long chain fat emulsion injection.MethodsThe chromatographic conditions were as follows: Kromasil 100-5-NH2 column(4.6×250mm,5μm) with the column temperature was 40℃,acetonitrile-water(8515)as mobile phase with flow rate of 1.0mL/min.Glycerol was detected by refractive index (RI) detector at 40℃.ResultsThe linear range of glycerol was 455.3916-2276.9580μg/mL(r=0.9999,n=7),the average recovery rate was 99.5%,RSD was 0.6%(n=9),the limit of detection(LOD) was 121ng and the limit of quantification(LOQ)was 364ng.ConclusionThe method was simple, rapid, strong specifity and accurate with good reproducibility, which is suitable for the content determination of glycerol in propofol medium and long chain fat emulsion injection.
