摘　　要：以石榴籽粉为原料,利用超声提取石榴籽油(PSO),对石榴籽油进行GC-MS分析,得到6种主要脂肪酸,其中9,12,15-十八三烯酸含量最高(71.538%)。Schaal烘箱法测定石榴籽油的抗氧化性,抗氧化优于VE;DPPH法测定石榴籽油具有清除自由基功能,结果清除率达80.61%;干燥实验测定石榴籽油干燥性能良好,可以作为僵化剂添加到油漆或者涂料中。Pomegranate seed oil （POS） was extracted with petroleum ether oil under the assistance of ultrasonic.Its fatty acid composition was analyzed by GC-MS and its biological and physical properties were also measured.POS was determined to contain 6 fatty acids,among which,the relative content of octadecanoic acid was the highest,71.538%.From the Schaal oven test results,the antioxidant effect of POS was better than that of VE.POS had excellent DPPH scavenging activity and the scavenging rate was up to 80.61%.In addition,PSO might provide a promising rigidity agent for paint production due to its excellent drying performance.
