In recent years, the determination of phenolic compounds in vegetable oil has aroused broad attention because these compounds have beneficial effects on health. In this work, a novel method based on the quick, easy, cheap, effective, rugged, and safe (QuEChERS) method and LC-MS/MS was developed for the analysis of phenolic compounds. A total of 18 mL of acetonitrile, 3 mL of water, and 270 mg of C sorbent were utilized in the optimized QuEChERS procedure. The LC-MS/MS analysis was performed in a C column under gradient-elution conditions with eluent of acetonitrile and water with 0.1% acetic acid. The QuEChERS approach achieved decent extraction recoveries (75.32-103.93%) for most phenolic compounds. The QuEChERS-LC-MS/MS method was validated in terms of accuracy, precision, sensitivity, and linearity. The proposed method was further evaluated using different prepared rapeseed oils. The result demonstrated that QuEChERS-LC-MS/MS is a rapid and reliable method for determining phenolic compounds in rapeseed oils.
近年来,植物油中酚类化合物的测定引起了广泛关注,因为这些化合物对健康有益。本工作建立了一种基于 QuEChERS 方法和 LC-MS/MS 的测定酚类化合物的新方法。在优化的 QuEChERS 方法中,使用了 18 mL 乙腈、3 mL 水和 270 mg C 吸附剂。LC-MS/MS 分析在 C 柱上进行,采用梯度洗脱条件,洗脱剂为乙腈和水,含 0.1%乙酸。QuEChERS 方法对大多数酚类化合物的提取回收率良好(75.32%-103.93%)。对 QuEChERS-LC-MS/MS 方法进行了准确度、精密度、灵敏度和线性度的验证。该方法进一步用于不同制备的菜籽油的评估。结果表明,QuEChERS-LC-MS/MS 是一种快速可靠的测定菜籽油中酚类化合物的方法。
