Antibacterial effect of juglans regia l bark extract at different concentrations against human salivary microflora

Objective: To evaluate and assess the anti bacteriogenic effect of the extract of bark of Derum (Juglans regia L.) at different concentrations on the salivary microflora. Materials and Method: This study is an experimental in vitro study designed to collect the salivary samples from the patients. All tests were performed under sterile conditions. Results: The results of the antimicrobial assay of the aqueous and acetone extracts of Derum (J regia L.) at different concentrations of 150 µg, 200 µg, 250 µg, and 300 µg showed that the aqueous extract had significant inhibitory effect on the growth of oral microbial flora compared to the acetone extract. Conclusion: This study supports the use of natural products as medicines and confirms the antibacterial potentials of the plant J Regia L. (Walnut)
