外文摘要：This study simultaneously synthesized three plant-derived zinc oxide nanoparticles (ZnO NPs-L, ZnO NPs-P, ZnO NPs-M) using loquat, perilla, and mulberry leaf extracts as reducing and capping agents. The results indicated that all three nanoparticles exhibited the typical hexagonal wurtzite structure with intact crystal lattices and high crystallinity. Characteristic ZnO absorption peaks appeared within the 370-380 nm range in the UV-Vis spectra, confirming successful nanoparticle formation. DLS and zeta potential analyses revealed uniform particle size distributions and negatively charged surfaces, indicating excellent colloidal stability. Antibacterial assays demonstrated inhibitory effects of all three ZnO NPs against Escherichia coli and Staphylococcus aureus, following the activity order ZnO NPs-L>ZnO NPs-P>ZnO NPs-M. DPPH· and ABTS·+ radical scavenging assays revealed antioxidant activity trends consistent with antibacterial performance. Overall, ZnO NPs-L exhibited superior bioactivity, dispersibility, and stability, highlighting their potential as sustainable nanomaterials for food packaging, biomedical applications, and environmental remediation. ? 2026, The Authors.
