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。

Abstract:

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.

Key words: pomegranate seed oil, ultrasonic, GC-MS, antioxidation, drying
