Abstract

Highlights: A novel magnetic sorbent (Fe3 O4 @ANDS) was fabricated via Lewis acid/base reaction. A new method for analysis of trans-resveratrol in peanut oils was developed by HPLC-UV detection. The sensitivity was comparative to the reported methods using LC-MS/MS detection. Fe3 O4 @ANDS possesses great potential for extracting polar analytes from oil matrix. Abstract: In the present study, a rapid and effective method based on alendronate sodium grafted mesoporous magnetic nanoparticle (Fe3 O4 @ANDS) extraction for the determination of trans-resveratrol (TRA) in peanut oils was developed by coupling with HPLC-UV detection. The Fe3 O4 @ANDS was prepared via Lewis acid/base interaction which was simply carried out in mild aqueous condition without the using of organic solvent. The resultant Fe3 O4 @ANDS encompassed amino group on its surface, and it was employed as magnetic solid-phase extraction adsorbent for purification and enrichment of TRA from peanut oils through hydrogen bond interaction. Under the optimized conditions, the whole pretreatment process could be accomplished within 10 min without time-consuming concentrated and reconstituted process. The linearity range of the proposed method was 1–10, 000 ng/g with satisfactory correlation coefficient (R 2 ) of 0.9992. The recoveries in spiked oil samples were in the range of 78.6–118.9% with the RSDs less than 3.3% (intra-day) and 15.2% (inter-day). The limit of detection for TRA in peanut oils was 0.3 ng/g which was comparative to the reported methods by using LC-MS/MS detection. Finally, the established method was successfully applied to the analysis of TRA in several peanut oils with different brands from local market as well as other kinds of vegetable oils.
