摘要: 本文研究了高效液相色谱仪测定甜菜红色素含量的方法。采用Shim-packvp-ODS色谱柱(150mm×4.6mmi.d.,5μm),流动相为A:甲醇、B:2%冰醋酸缓冲液(A:B=20:80V/V),流速0.7ml/min,检测波长为535nm。甜菜红色素质量浓度在0.0641~3.206mg/ml范围内与峰面积呈良好线性关系,相对标准偏差为1.13%。,回收率为97.58%~102.10%。本方法操作简便、灵敏、可靠、适用于甜菜红色素的分析测定。

Abstract: A method for determination of betalain was described by high performance liquid chromatrgraphy. Shim-pack vp- ODS column(4.6mm i.d. ×150mm, 5μm)was used and mobile phase was MeOH:H 2O-HAc(20: 80) with flow rate of 0.7ml/min. The eluate was monitored at λmax=535nm . The linearity was obtained over the range of 0.0641 ~3.206mg/ml ( r = 0.9999).The determination limit was 0.06 4μg/ml.The average recovery of sample was in the range of 97.58% ~102.10%, with relative standard deviation of 1.13%. The method was proved to be a simple, rapid and reliable way to determine the betalain concentration.
