摘要
建立了辣椒中辣椒红色素的高效液相色谱法定性定量检测方法。结果表明,采用v(正己烷)v∶(丙酮)=782∶2为最佳流动相,检测波长475nm,分析柱Shim-pack CLC-SIL(M)(150×4.6mmID),流速:0.8mL/min,柱温40℃,使辣椒红色素在10min内得到了较好的分离。线性范围为0.022 ̄0.176mg/mL,r=0.9994,平均回收率为99.17%,变异系数为1.63%(n=5),最小检测限为10ng。该方法具有简单快速、精密度高等优点。
A method for the simultaneous determination of capsicum red pigment in pepper by high performance liquid chromatography has been established. The result showed that the best mobile phase was hexan:acetone (78: 22) detected at 475nm. The experiments were carried on by Shim-pack CLC-SIL (M) (150x4.6mm ID) at a flow rate of 0.8mL/min, which make it get better separation in 10min. The calibration curve was linear in the range of 0.022- 0.176mg/mL with r=0.9994. The average recovery percent was 99.17% with CV=1.63%(n=5). The detection limits were 10ng. The method is suitable for the detection of capsicum red pigment in pepper.
