| 摘 要： | 采用超声波辅助提取从黑莓籽中提取籽油,用GC/MS方法对籽油脂肪酸成分进行了分析,并通过测定籽油清除DPPH自由基的能力对黑莓籽油的抗氧化能力进行了评价。结果表明:黑莓籽油中不饱和脂肪酸占68.48%,对DPPH自由基清除能力研究表明1 mL黑莓籽油的抗氧化能力相当于2.092 mg抗坏血酸,具有良好的抗氧化能力。 |
| 关 键 词： | 黑莓籽油 气相色谱-质谱法 不饱和脂肪酸 抗氧化活性 |

| 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 radic... |
| Keywords: | blackberry seed oil GC/MS unsaturated fatty acids antioxidant activity |
