A rapid analytical approach for the assay of resveratrol in red wines, based on Paper Spray Mass Spectrometry (PS-MS) and Multiple Reaction Monitoring (MRM) is described. The assay involves the use of the stable isotope dilution method. The analytical parameters calculated analyzing fortified samples confirm the reliability of the proposed approach, with accuracy values about 100%, and LOD and LOQ values calculated at 0.5 and 0.8μg/mL, respectively. Furthermore, both the recovery, which was quantitative for the analyte, and the reproducibility (RSD%), checked on different days on the same wine, always below 7%, highlighted the consistency of the methodology.
本文描述了一种基于纸喷雾质谱（PS-MS）和多反应监测（MRM）的快速分析测定红酒中白藜芦醇的方法。该测定方法采用稳定同位素稀释法。对加标样品进行分析计算得出的分析参数，证实了该方法的可靠性，其准确度值约为 100%，LOD 和 LOQ 值分别计算为 0.5 和 0.8μg/mL。此外，对同一样品在不同日期进行的回收率（分析物定量）和重现性（RSD%）的检查，均低于 7%，这突出了该方法的一致性。
