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.

Key words: Passiflora edulis rind, nutritional components, total polyphenol, total flavonoids, antioxidant activity
