摘要:

目的:建立同时测定功能性饮料中VC、VPP、VB6、VB2 和VB1 水溶性维生素含量的RP-HPLC 方法。方法:色谱条件:色谱柱:Luna C18(2)(200mm ×4.60mm,5μm),流动相:0.005mol/L 己烷磺酸钠溶液- 甲醇-冰醋酸(80:20:0.5,V/V)(pH4.0),流速1.0mL/min,检测波长278nm。结果:VC、VPP、VB6、VB2 和VB1 的线形范围分别是2.94~43.50、6.00~90.00、1.70~25.50、1.60~24.00、2.30~43.50μg/mL,最低检出限分别为0.001、0.362、0.095、0.328、0.619μg/mL;VC、VPP、VB6 平均回收率分别为98.29%、98.38%、98.51%。结论:此方法简单、快捷、准确,可同时测定功能性饮料中的多种水溶性维生素。

Abstract:

Objective: To develop an HPLC method for the simultaneous determination of several water-soluble vitamins in functional beverages. Methods: Luna C18(2) column (200 mm × 4.60 mm, 5μm) was used as stationary phase. The mobile phase was composed of 0.005 mol/mL hexanesulfonste sodium, methanol and glacial acetic acid (80: 20: 0.5) at pH 4.0. The flow rate was 1.0 mL/min. The wavelength of UV detection was set at 278 nm. Results: The standard curves developed exhibited a good linear over a range of 2.94-43.50μg/mL for VC, 6.00-90.00μg/mL for VPP, 1.70-25.50μg/mL for VB6, 1.60 -24.00μg/mL for VB2, and 2.30-43.50μg/mL for VB1. The detection limits for VC, VPP, VB6, VB2 and VB1 were 0.001, 0.362, 0.095, 0.328μg/mL and 0.619μg/mL, respectively. The average recoveries were 98.29% for VC, 98.38% for VPP and 98.51% for VB6. Conclusion: This method is simple, fast and accurate. It allows the simultaneous determination of water-soluble vitamins in functional beverage.
