MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202611026944 A) filed by Dr Arun Bhardwaj; Dr. Ranjana Patnaik; and Prof. Dr Niranjan Kaushik, Greater Noida, Uttar Pradesh, on March 7, for 'use of bioactive extract of juglans regia l. bark as an antimicrobial agent against oral pathogens.'
Inventor(s) include Dr Arun Bhardwaj; Dr. Ranjana Patnaik; and Prof. Dr Niranjan Kaushik.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "The current disclosure pertains to the application of bioactive extracts derived from the bark of Juglans regia L. as an antimicrobial agent against oral pathogenic microorganisms. Disc diffusion and agar well diffusion assays are used to test the antibacterial activity of methanolic and ethanolic extracts of Juglans regia bark in vitro. The concentrations range from 5 g/mL to 40 g/mL. The extracts show that they can stop oral pathogens like Pseudomonas aeruginosa, Staphylococcus aureus, and Streptococcus mutans from growing. The inhibition zones we saw show that the antimicrobial activity depends on the concentration and is similar to that of standard antimicrobial agents like chlorhexidine and octenidine. The findings demonstrate that Juglans regia bark extract exhibits considerable antimicrobial efficacy against oral pathogens and may serve as a natural antimicrobial agent for prospective oral healthcare applications."
