The purpose of this study was to obtain and characterize of some fresh pumpkin juices with addition of water, walnuts, honey, cinnamon and fresh peppermint leaves. Total soluble content, vitamin C by titration with a 2,6-dichlorophenolindophenol sodium, antioxidant capacity by FRAP assay and total phenolic content by Folin-Ciocalteu method were analyzed. Vitamin C content ranged from 0.09 to 0.15 mg/mL, with 0.13 mg/mL in individual pumpkin juice; the juice assortment without walnuts has the lower vitamin C content. Among the investigated juices, the pumpkin juice assortment with all ingredients have the higher amount total polyphenol content (4.19 mM GAE/mL) and the total antioxidant capacity (2.53 mM Fe2+/mL). We observed that the fresh pumpkin juice assortments are a real source of bioactive compounds.
