摘要:
采用高效液相色谱法测定保健食品中维生素B12含量,色谱柱用Agilent ZORBAX SB-Aq(4.6mm×250mm,5μm),流动相为甲醇-0.2%磷酸水溶液(38:62),流速1.0ml/min,检测波长361nm。结果是维生素B12线性范围为0.816~4.08μg,r=0.9997;平均回收率为97.2%,RSD为1.39%(n=6),最小检出限为0.85μg/g。高效液相色谱法灵敏度高,操作简便,重现性好,结果准确,可以用于保健食品中维生素B12的质量控制。

Abstract:
A method for detemination of Vitamin B12 heath care food by HPLC was created.The method contained a Agilent ZORBAX SB-Aq(4.6×25nm,5μm) column,with methanol-0.2%Phesphoric Acid(38:62) as mobile phase,rate 1.0ml/min,detection wavelength at 361nm.Linarity range:0.1864.08μg,r=0.9997,the average recovery of Vitamin B12 was 97.2%,the RSD of results was 1.39%(n=6),minimal detection value 0.85%μg/g.The method is sensitive,simple,precise and accurate.This study provides a test method for the quality control of health care food.
Key words:  HPLC  vitamin B12  determination  health care food
