目的::建立一种高效液相色谱法测定乳制品中香兰素含量的方法。方法:以18种乳制品为样品,采用C18(250 mm ×4.6 mm,5μm)反相色谱柱,甲醇-水(35∶65)为流动相,流速为1.0 ml·min-1,检测波长为275 nm。结果:结果表明,各种不同基质样品中香兰素检出限为0.450μg·ml-1,浓度在1.990~99.500μg·ml-1的范围内呈线性关系(r=1.0000),低、中、高三水平回收率在96.26%~100.81%之间,RSD在0.15%~2.22%之间。结论:该方法操作简便,结果可靠,可用于乳制品中香兰素含量的快速测定。

Objective:To establish an HPLC method to determine vanillin in 18 dairy products. Methods:The samples were sep-arated on a C18 column (250 mm × 4. 6 mm, 5 μm) with the mobile phase of methanol and water (35∶65) at the flow rate of 1. 0 ml ·min-1 . The detection wavelength was 275 nm. Results:The LOD ( limit of detection) of vanillin was 0. 45 μg·ml-1 . Excellent linearity was obtained within the concentration range of 1.990-99.500 μg·ml-1(r=1.000 0). The average recovery of vanillin in different dairy products with low, medium and high levels varied between 96. 26% and 100. 81% with RSD of 0. 15%-2. 22%. Con-clusion:The method is simple and reproducible, which can be applied in the rapid analysis of vanillin in dairy products.
