AB  - In this study, a simple and convenient method for the determination of 
      trans-resveratrol (TRA) in peanut oils based on pollen grain solid-phase 
      extraction (SPE) was developed. Pollen grains were used as normal-phase SPE 
      sorbent to separate TRA from peanut oils for the first time. As a naturally 
      occurring material, pollen grains exhibited an excellent adsorption capacity for 
      polyphenolic compounds due to their particular functional structures such as 
      hydroxyl groups, saturated and unsaturated aliphatic chains with aromatics. Their 
      stable compositions as well as adequate particle size (30-40 mum) also make them 
      suitable for SPE. Several parameters influencing extraction performance were 
      investigated. Coupled with high-performance liquid chromatography-ultraviolet 
      detection (HPLC-UV), a green purification method for fast determination of TRA in 
      peanut oils using pollen grain cartridges as sorbents was established. The 
      linearity range of the proposed method was 10-2500 ng . g(-1) with a satisfactory 
      correlation coefficient (r(2)) of 0.9999. The limit of detection (LOD) for TRA in 
      peanut oils was 2.7 ng . g(-1), and the recoveries in spiked oil samples were 
      from 70.2% to 98.4% with the relative standard deviations (RSDs) less than 4.9% 
      (intraday) and 5.2% (interday). This 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.
