摘　　要：建立了一种基于固相萃取前处理方法结合气相色谱同时测定食用植物油中BHA、BHT和TBHQ的方法.样品经固相萃取方法处理,浓缩后,采用HP-5毛细管色谱柱分离,以FID检测器进行分析.3种抗氧化剂的线性相关系数(r)均大于0.999,方法检出限分别为0.2、0.1、0.2 mg/kg.方法的准确性、精密度均能满足检测的要求,可用于食用植物油中3种抗氧化剂的检测.Abstract： A method was established for the simultaneous determination of BHA, BHT and TBHQ in edible vegetable oil by solid-phase extraction with gas chromatography. The samples were treated by solid-phase extraction, and analyzed with the FID detector after concentration by using the HP-5 capillary chromatographic column. The correlation coefficients （r） of three antioxidants were not less than 0.999, and the detection limits were 0.2 , 0.1, 0.2 mg/kg, respectively. The method has good accuracy and precision, it can be applied to the simultaneous determination of BHA, BHT and TBHQ in edible vegetable oil.
