ABSTRACT
In the present study, a rapid and effective method based on alendronate sodium grafted mesoporous magnetic nanoparticle (Fe3O4@ANDS) extraction for the determination of trans-resveratrol (TRA) in peanut oils was developed by coupling with HPLC-UV detection. The Fe3O4@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 Fe3O4@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 10â¯min without time-consuming concentrated and reconstituted process. The linearity range of the proposed method was 1-10,000â¯ng/g with satisfactory correlation coefficient (R2) 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 0.3â¯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.
