摘要
采用香豆素类物质BDMC为衍生剂进行柱前衍生,以C8反相柱(4.6mm×150mm)为固定相,乙腈-甲醇-水(35:10:55)为流动相,流速为1.5mL/min,柱温为22℃,检测波长为Ex/Em=354nm/440nm,建立定量检测体外培养巨噬细胞液中PGF2α的HPLC方法.PGF2α峰呈尖峰,分离度良好;在25~500μg/L范围内成线性(R^2=0.9950);其精密度RSD为4.34%(n=5);重复性RSD为7.88%(n=6),稳定性RSD为4.43%(n=5);平均加样回收率为87.20%±7.63%(n=3).结论:该方法稳定、可靠、重复性好,可用于体外培养巨噬细胞液中PGF2α的定量检测.
Pre-column derivate agent: BDMC; column: C8 (4.6nm × 150mm) ; mobile phase: acetonitrile-methmot-water ( 10 : 35 : 55 ). Flow rate: 1.5mL/min; detection wavelength: Ex/Em = 354nm/440nm; injection volume:20μl: at room temperature. The peak of PGF2α appeared agile;rate of separation was fine;in the range of 25μg/L to 500μg/L, the amounts were linearly related with the peak areas(R^2 = 0. 9950) ; the RSD of precision rate was 4.34 % ( n = 5 ) ; the RSD of repeatability was 7.88 % ( n = 6) ; the RSD of stability was 4.43 % ( n = 5) ; the average recover rate was 87.20 % ~ 7.63 % ( n = 3). Conclusions: This analysis is a highly repeatable and accurate analyzing approach for PGF2α.
