Abstract

The present study aimed to analyze the nutritional properties, phytochemicals content and antioxidant activities of four wild edible fruits such as Ishe (Mimusops kummel Bruce ex A.DC), Kega (Rosa abyssinica R.Br.), Kurkura (Ziziphus spina-christi L. Desf.), and Lenkuata (Grewia ferruginea Hochst. ex A) that are commonly consumed as natural food sources. The physicochemical composition and phytochemical screening analysis were evaluated. Functional groups present in all fruits were identified using FTIR spectroscopy. Polyphenols such as total phenolic content (61 ± 1.02 to 98.3 ± 0.44 mg GE/100g of fruit paste) and total flavonoids content (24.1 ± 0.10 to 87.1 ± 0.44 mg QE/100g of fruit paste) in fruits were analyzed. Free radical scavenging activity (DPPH assay) in terms of half maximal inhibitory concentration, IC50% (108.31 to 401.7 µg/mL of fruits paste) was analyzed. Antioxidant potential, reducing and stabilizing ability were also confirmed via synthesis of silver nanoparticles rationalized by the involvement of phytochemicals. Therefore, fruits of this study showed important nutritional, phytochemical, and antioxidant properties with biological interest, and can be a potential source of functional ingredients and nutraceuticals.
