测定了苹果、石榴、橄榄、芒果、香蕉、菠萝、葡萄和龙眼的壳、肉及核中的多酚含量及其抗氧化性.以70%丙酮(v/v)为提取溶剂,室温下超声波辅助浸提样品后得到提取液.采用普鲁士兰(Prussian blue)法测定了提取液中多酚和单宁的含量,利用FRAP法测定其抗氧化性.结果表明:提取液中多酚和单宁的含量均与其抗氧化性成正相关关系;石榴、橄榄、芒果、葡萄和龙眼等水果的壳与核有望成为天然抗氧化剂的新来源.

The contents of polyphenols of peel,pulp and seed fractions of apple,pomegranate,olive,mango,banana,pineapple,grape and longan and their total antioxidant activities were studied.After ultrasound-assisted extraction with 70%aqueous acetone at room temperature,polyphenols and tannins in the plant ceHs were separated and their contents were determined by Prussian blue assay.Antioxidant activities of the aqueous acetone extracts were evaluated by Ferric Reducing/Antioxidant Power(FRAP)assay.A positive linear correlation between antioxidant activities and phenolic contents was observed.The results showed that the fruit peel and seeds of pomegranate,olive,mango,grape and longan could be considered as potential sources of antioxidants rather than just discarded as waste.
