Abstract
Olive (Olea europaea L.) leaf extract (OLE) has a repository of secondary metabolites with a unique potential for anti-inflammatory, anticancer, antidiabetic, antimicrobial, antiviral, hypoglycaemic, hypolipidemic, and antioxidant activity. As Olive leaves are bestowed with all these therapeutic activities, green synthesis of Zinc Oxide Olive leaf extract nanoparticle was attempted, and subsequently, its antimicrobial activity was also assessed in the present study. The Arbequina and Coratina varieties of Olives, showed a marked difference in oleuropein and hydroxytyrosol content. The leaves of both the varieties were assessed for their nanoparticle biosynthesis, characterization, and their antimicrobial activity. The antimicrobial activity of the Olive variety, Coratina was more against both Bacillus subtilis and Staphylococcus aureus in comparison to Olive cultivar Arbequina. Profound bacteriocidal activity was observed by the nanoparticles produced by the Cortina in comparison to the Arbequina variety of Olive. The antimicrobial activity of the Olive and its nanoparticles may be due to the secondary metabolite content. Using olive leaf extracts, the zinc oxide nanoparticle formed can be used, in the future for the synthesis of cosmetic formulations.
