Aim: To evaluate the antibacterial activity of copper nanoparticles using lodhra bark against Staphylococcus aureus and Lactobacillus species. Introduction: Symplocos racemosa also known as Lodhra, is a drug used by Ayurvedic practitioners. Theroot, bark and leaves of this plant is traditionally used for the treatment of diarrhoea, leprosy, uterine and liver disorders. Materials and methods: The plant extract is prepared by mixing 100 ml of distilled water, boiled and filtered using a filter paper. The copper nanoparticles are prepared by mixing copper sulphate powder to 500 ml of distilled water. Readings were taken frequently, and the synthesis of copper nanoparticles were analysed. Agar well diffusion method was used to evaluate the antimicrobial activity of both S.aureus and Lactobacilli species. Results: S.aureus showed a higher inhibition area than Lactobacillus. Conclusion: There is a future potential for these copper nanoparticles for combating pathogenic microorganisms.
