Objective Clarify and optimize the detection methods for 9antioxidants in oil samples. Methods After dissolving the oil sample in $3\mathrm{\;{mL}}$ of n-hexanesolution saturated with acetonitrile, repeat the extraction 5 times with $3\mathrm{\;{mL}}$ of n-hexanesaturated acetonitrile containing AP, and merge the 5 extractionsolutions. Purify with a C18 solid-phase extraction column, collect andconcentrate all extraction and eluent together to ${0.2}\mathrm{\;{mL}}$ , and finally make upto $2\mathrm{\;{mL}}$ withacetonitrile. Results 9 antioxidants linear relationship is good withinthe range of 1.0 to ${60.0}\mathrm{{\mug}}/\mathrm{{mL}}$ , and the correlation coefficients are allgreater than 0.99 ; the recovery rate ranges from 91.2% to 108.8%, witha relative standard deviation (RSD) of 0.6% to 10.0%; the detectionlimit is within the range of ${0.2}\sim {2.0}\mathrm{{mg}}/\mathrm{{kg}}$ ,and the quantitative limit is within the range of ${0.6}\sim {6.0}\mathrm{{mg}}/\mathrm{{kg}}$ . Conclusion This method optimizes the extraction frequency, purification method, and elution volume, and significantly improves the recovery rates of 9 antioxidants. The extraction frequency has a significant impact on the recovery rate of BHT and DG.

目的 明确和优化油类样品 9 种抗氧化剂的检测方法。方法 油类样品用3 mL 乙腈饱和的正己烷溶液溶解后,用 $3\mathrm{\;{mL}}$ 含 $\mathrm{{AP}}$ 的正己烷饱和的乙腈重复提取5 次,合并 5 次提取液。用 C18固相萃取柱净化,全部提取液和洗脱液一起收集浓缩至 ${0.2}\mathrm{\;{mL}}$ ,最后用乙腈定容至 $2\mathrm{\;{mL}}$ 。结果 9种抗氧化剂在 ${1.0}\sim {60.0}\mathrm{{\mug}}/\mathrm{{mL}}$ 范围内线性关系良好, 相关系数均大于 0.99;回收率 91.2%~108.8% 之间,相对标准偏差 (RSD) 为 0.6%~10.0%;检出限在0.2~2.0 mg/kg 范围, 定量限在 ${0.6}\sim {6.0}\mathrm{{mg}}/\mathrm{{kg}}$ 范围。结论 本方法通过优化提取次数、净化方法和洗脱体积,9种抗氧化剂的回收率均有显著提高,其中提取次数对 BHT、DG的回收率影响较大。
