Summary: This study investigated the antioxidant and antibacterial capabilities of zinc oxide nanoparticles (ZnONPs) synthesized using methanolic leaf extracts of the medicinal herb Viscum album. The synthesis of ZnONPs was confirmed by TEM and UV-Vis analysis. The green-manufactured ZnONPs showed superior antibacterial activity compared to the wild herbal medicinal extracts, and the aqueous extracts of ZnONPs had higher concentrations of DNA gyrase-B inhibitory components. The methanolic extracts exhibited higher antioxidant capacity compared to the aqueous extracts.

Summary: This study compared ZnONPs prepared by two different green methods - high temperature heating and low temperature method with suspending agents and pH variations. The low temperature method resulted in ZnONPs with high retention rate and size around 200 nm. These improved ZnONPs showed significant hypoglycemic effects at a lower dosage.
