Open publisher page 0 citations

Abstract

The determination of nine antioxidants has been studied by using HPLC. After the sample is resolved in hexane and extracted with acetonitrile, and concentrated, it can be determined by HPLC. The detection limit of PG, THBP, NDGA, OG, DG are 0.5μg/g,TBHQ, BHA, IONOX-100, BHT are 1μg/g with relative standard deviation is 1.01%~6.89%. The recoveries of the nine compositions are from 88.85% to 102.57%. The method is simple, efficient and accurate and suitable for analysis of antioxidants in edible oil .
