摘要
采用超声辅助和加热回流法,以70%乙醇为溶剂,提取了树菠萝壳和榴莲壳中的总黄酮,以芦丁为参照物,通过分光光度法测定了其总黄酮含量,并通过羟自由基清除试验评价了其乙醇提取物的抗氧化活性。结果表明:树菠萝壳和榴莲壳均含有一定量的黄酮类化合物,其含量分别为42.28 mg·g-1和8.31 mg·g-1,并且其乙醇提取液均表现出一定程度的抗氧化活性。
The total flavonoids in the peels of the jackfruit Artocarpus heterophyllus and the durian Durio zibethinus L. were extracted with 70% ethanol by means of ultrasonic and reflux. And the content of the total flavonoids were determined by spectrophotometry with lutin as an indicator, meanwhile the antioxidation activity of their ethanol extracts were also evaluated by the experiment of hydroxyl radical scavenging activity. The results showed that the contents of the total flavonoids in the peels of the jackfruit Artocarpus heterophyllus and the dulian Durio zibethinus L. were 42.28 mg/g and 8.31 mg/g, respectively, and both the ethanol extracts of the peels of the jackfruit Artocarpus heterophyllus and the durian Durio zibethinus L. showed moderate antioxidation activity.
