摘要
目的研究饲料中没食子酸丙酯(PG)、特丁基对苯二酚(TBHQ)、乙氧基喹(EQ)、丁基羟基茴香醚(BHA)、没食子酸辛酯(OG)、二丁基羟基甲苯(BHT)、没食子酸十二酯(DG)和正二氢愈创酸(NDGA)共8种抗氧化剂同时检测系统技术。方法样品提取后采用自动固相萃取方式；定量分析采用高效液相色谱-梯度淋洗-二极管阵列检测器方法进行检测。结果最低检测限为10 mg/kg；饲料中8种抗氧化荆含量在10 mg/kg时实验精密度为1．60％-10．46％；添加抗氧化剂的回收率在84％～106％；。结论该方法具有高效率,高灵敏度,准确度好,可靠性高等技术特点。
Objective In this paper a method for simultaneous determination of 8 antioxidants （PG, TBHQ, EQ, BHA, OG, BHT, DG and NDGA）in animal feed by HPLC was described. Methods Samples were cleaned up with auto solid phase extraction and determined by HPLC using gradient elution-PDA detector. Results The detection limits were 10 mg/kg, rate of recovery and RSDs of the method were 84%-106% and 1.60%-10.46% at this concentration. Conclusion The method described has high efficiency and sensitivity, with good stability and veracity.
