摘要
To establish a method for the determination of rosin in meat and their products by using high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS), the sample was extracted by ultrasonic instrument with acetonitrile. The extracts were then purified through solid-phase extraction (SPE) with C18 cartridges. The target of dehydroabietic acid was analyzed by HPLC-MS/MS, and quantified by internal standard method. The separation was performed on a Waters ACQUITY HSS T3 column (2.1 mm×100 mm, 1.8 μm) with isometric elution using 0.1%(v/v)formic acid aqueous solution-acetonitrile (30:70) as the mobile phase.The analysis of dehydroabietic acid was detected under electrospray positive ionization mode and the multiple reaction monitoring(MRM) mode. The dehydroabietic acid demonstrated good linearity in the range of 5~400 ng/mL, with the correlation coefficient values (r) being higher than 0.99. The limits of detection (LODs) and limits of quantification (LOQs) were found to be 80 and 200 μg/kg. The recoveries at three spiked levels (200, 400 and 2000 μg/kg) in blank matrix were in the range of 96.05%~104.17% with the relative standard deviations between 0.62%~3.68% (n=6). The analysis results of actual samples showed that the number of positive samples of dehydroabietic acid accounted for 16.67% of the total samples, and the residual content was in the range of 390.15~1850.03 μg/kg. The method was convenient, rapid, accurate and efficient. It could be employed for accurate determination of rosin in meat and their products. © 2021 Science and Technology of Food Industry.
