                 Abstract: ZnO nanoparticles (Nano ZnO) were synthesized via solution combustion method with flavone
                 from Ampelopsis grossedentata as raw materials and characterized by FTIR, XRD, SEM and EDS. The
                 antioxidant and bacteriostatic  properties of  the greenly  synthesized  Nano  ZnO were evaluated by
                 Brand-Williams method, inhibition zone method and minimum inhibitory concentration method. The results
                 indicated that the greenly synthesized Nano ZnO had a hexagonal wurtzite structure with good crystallinity
                 and its average grain size was about 32.7 nm. Moreover, the Nano ZnO had good antioxidant activity. When
                 the mass concentration of Nano ZnO was 2.5 g/L, the scavenging rate of 1,1-diphenyl-2-picrylhydrazyl free
                 radical (DPPH•) reached 98.24%. Furthermore, the antibacterial activity of greenly synthesized Nano ZnO
                 against Staphylococcus aureus was higher than that of traditional chemically synthesized Nano ZnO. The
                 minimum bacteriostatic concentration of greenly synthesized Nano ZnO was  1.00 g/L, while that of
                 chemically synthesized Nano ZnO was 1.50 g/L.
