Gold nanoparticles (AuNPs) were synthesized by one-step reduction of chloroauric acid using pomelo leaf polyphenol extract as reducing and protective agent. The AuNPs were characterized by UV-Vis absorption spectroscopy. Compared with AuNPs prepared with sodium citrate as reducing agent, AuNPs prepared with pomelo leaf polyphenol extract had better stability. The antioxidant properties of green-synthesized AuNPs were investigated by Bland-Williams method. The antibacterial activity of the green synthesized AuNPs was investigated by the transparent inhibition zone method and the minimum inhibitory concentration method. The results showed that the AuNPs prepared with pomelo leaf polyphenol extract as biological template had good antioxidant activity. The scavenging rate of 1, 1-diphenyl-2-trinitrophenylhydrazide free radical (DPPH•) was 95.65% when the 1.0 g/L AuNPs solution was used. The antibacterial activity of AuNPs synthesized from pomelo leaf polyphenol extract against Staphylococcus aureus was higher than that of AuNPs synthesized chemically. The minimum inhibitory concentration of green synthesized AuNPs was 0.85 g/L, while the minimum inhibitory concentration of chemically synthesized AuNPs was 1.58 g/L.
