摘要: 以西番莲果皮为原料,分析西番莲果皮的营养成分和功能性成分,并对西番莲果皮抗氧化活性进行研究。结果表明,西番莲果皮中含有丰富的碳水化合物、多糖、黄酮和多酚类物质。其中果胶和粗纤维含量分别为12.5%和22.1%,多糖含量为20.62±0.21g/100g,总黄酮含量为1180.67±16.73mg/100g,总酚含量为2811.24±22.74mg/100g。西番莲果皮的乙醇、水提取物都具有良好的抗氧化活性,均能有效清除DPPH·和·OH。果皮提取物的自由基清除能力与质量浓度呈明显的量效关系,最高清除率分别达91.62%和81.97%。

Abstract: The Passiflora edulis rind was investigated on its nutritional components,functional components and antioxidant activity.The results showed that the Passiflora edulis rind is rich in carbohydrate,polysaccharides,flavonoids and polyphenols.The contents of pectin and crude fiber are 12.5% and 22.1% respectively,the content of polysaccharide is 20.62±0.21 g/100g,the content of total flavonoids is 1180.67±16.73 mg/100 g,and the content of total polyphenol is 2811.24±22.74 mg/100 g.The crude extracts of the Passiflora edulis rind by ethanol and water have good antioxidant capacit,which can effectively scavenge DPPH· and ·OH.The scavenging capabilities of the crude extracts are obviously related to their concentrations,and the maximum scavenging rates are 91.62% and 81.97% respectively.
