The present study is aimed at determining the total flavonoid and phenol contents and antioxidant properties of Silver nanoparticles (AgNPs) biosynthesized using unripe pawpaw peel (UPPAE) and banana peel (UBPAE) aqueous extracts. AgNPs of UPPAE and UBPAE were synthesized separately by reducing AgNO3 with UPPAE and UBPAE respectively. Primary characterization was done on the synthesized AgNPs with a UVvisible spectrophotometer, and their antioxidant properties were evaluated using DDPH, ABTS, FRAP assays. The reaction mixtures of AgNO3 solution and the agro-waste extracts turned dark brown for AgNO3 + UPPAE and light brown for AgNO3 + UBPAE and also displayed a UV-visible spectrum of 450 nm and 421 nm respectively which is characteristic of silver nanoparticles. The result of the total flavonoid contents revealed that AgNPs-UPPAE had the highest amount of flavonoid content (499.89 ± 1.96 mgQE/g) and phenol content (85.30 ± 0.57 mgGAE/g).
