黑莓籽油脂肪酸成分及抗氧化活性研究_张东升 . Study on Chemical Components of Blackberry Seed Oil and its Antioxidant Activity

Abstract

In this paper,ultrasonic extraction was applied to extract oil from blackberry seeds,and then the chemical components of the oil was analyzed by GC/MS.Its antioxidant activity was assessed by the DPPH radical scavenging assay.The results showed that in blackberry seed oil,unsaturated fatty acids occupied 68.48 % of the total fatty acids and the antioxidant activity of 1mL blackberry seed oil corresponded to 2.092 mg ascorbic acid.It revealed that the oil had considerable effect on scavenging DPPH free radical.
