高效液相色谱法测定黄疸患婴血清中维生素B2
Determination of Vitamin B2 in the Serum of Icterus Diseased Infant by the High Performance Liquid Chromatography
【摘要】 采用O asis C18小柱吸附富集血清中的维生素B2,除去蛋白质等杂质的前处理手段,以Phenom enex LunaC18柱为分析柱、甲醇∶0.02m ol/L乙酸铵为3∶7为流动相,荧光检测器(激发波长425nm,发射波长525nm)测定维生素B2含量。方法的平均回收率为98.0%,RSD为1.2%,最低检出浓度为0.8ng/m l。本方法操作简便,能快速、准确地检测人体血清中维生素B2含量。
【Abstract】 The article created a method for determination of VitB2 in serum of icterus diseased infant by HPLC,Before the determination,absorb pregnant VitB2 in serum through the Oasis C18 column,removing the impurity of hemocyanin and so on.Taking the phenomenex Luna C18 as the analytical column,the methanol:0.02mol/L aminum actetate=3∶7 as the mobile phase,the fluoresce detector(Excitation wavelength was 425 nm;Emission wavelength was 525nm).The method avergage recovery is 98.0%,RSD=1.2%,and the lowest certified concentration is 0.8ng/ml.The method is simple,rapid and accurate in determining VitB2 in serum of human body.
