摘　　要：研究了固相萃取-气质联用测定辣椒油中苏丹红Ⅰ和苏丹红Ⅱ的分析方法。用Strata-X小柱进行辣椒油样品的前处理,用气质联用法对苏丹红Ⅰ和苏丹红Ⅱ进行定性和定量分析。对苏丹红Ⅰ和苏丹红Ⅱ方法的检出限分别为0.5μg/L和0.7μg/L,平均回收率分别为93.8%和95.9%,RSD分别为2.7-6.9%和1.1-4.4%。A novel method for the determination of Sudan Ⅰ and Sudan Ⅱ in Hot Chilli Oil is developed. Solid phase extraction (SPE) is carried out on a Strata-X column. Sample aliquots are analyzed qualitatively and quantitatively with GC/MS. The detection limits , recovery , and precision are 0.5 μg/L,93.8 % ,and 2.7-6.9 % for Sudan Ⅰ respectively ,0.7 μg/L,95.9 %,andl.1-4.4 % for Sudan Ⅱrespectively.
