中文摘要: 建立一种超高效液相色谱-串联质谱分析运动饮料中 VB1 、VB2 、VB5 、VB6 、VB7 、VB9 、VB12 、烟酸、烟酰胺、VC 10 种水 溶性维生素的方法。样品前处理用 10 %乙醇沉淀提取后,采用 Waters Atalantis T3 色谱柱(2.1 mm×150 mm,3 μm)分
离,以 0.1 %甲酸-10.0 %甲醇为流动相的梯度洗脱模式下,10 种水溶性维生素在 10.0 ng /mL~1 000.0 ng/mL 浓度范围 内线性良好,相关系数 r2 为 0.999 3~0.999 9,检出限范围为 0.10 μg/kg ~11.5 μg/kg,定量限范围为 0.35μg/kg ~38.0 μg/ kg,加标回收率为 90.3 %~99.5 %,相对标准偏差(RSD)为 2.0 %~3.6 %。

Abstract:The determination of 10 kinds of water-soluble vitamins, including vitamin B1, vitamin B2, vitamin B5, vitamin B6, vitamin B7, vitamin B9, vitamin B12, niacin, nicotinamide, vitamin C in sports drink ,was es- tablished by ultra high performance liquid chromatography mass spectrometry.After the sample was treated with 10 % ethanol to precipitation extraction, the separation of target compound was performed on a Waters Atalantis T3 chromatographic column (2.1 mm×150 mm, 3 μm) using 0.1 % formic acid-10.0 % methanol as mobile phase under gradient elution mode. The linear range of 10 kinds of water-soluble vitamins was in the range of 10.0 ng/mL~1 000.0 ng/mL with a correlation coefficient of 0.999 3-0.999 9. The detection limit was 0.10 μg/kg -11.5 μg/kg and the quantitative limit was 0.35 μg/kg-38.0 μg/kg. The recovery rate was 90.3 %-99.5 %, and the relative standard deviation(RSD)was 2.0 %-3.6 %.
