MUMBAI, India, March 13 -- Intellectual Property India has published a patent application (202611009619 A) filed by Ashoka Institute Of Technology And Management; Ms. Anshika Singh; Mr. Himanshu Upadhyay; Ms. Krishna Raj Soni; Ms. Shagun Singh; Ms. Srishti Soumya; Er. Arifa Siddiqui; Dr. Sumedha Ojha; and Dr. Sarika Shrivastava, Varanasi, Uttar Pradesh, on Jan. 30, for 'extraction of onion seed oil and its antimicrobial and biological activity against microbial consortia.'

Inventor(s) include Ms. Anshika Singh; Mr. Himanshu Upadhyay; Ms. Krishna Raj Soni; Ms. Shagun Singh; Ms. Srishti Soumya; Er. Arifa Siddiqui; Dr. Sumedha Ojha; and Dr. Sarika Shrivastava.

The application for the patent was published on March 13, under issue no. 11/2026.

According to the abstract released by the Intellectual Property India: "The present invention relates to a reproducible method and system for extraction, characterization, and biological evaluation of onion seed oil derived from Allium cepa. Onion seeds are cleaned, dried, and ground, followed by oil extraction using solvent-based cold maceration and Soxhlet extraction techniques under controlled laboratory conditions. The extracted oil is recovered under reduced pressure and quantitatively evaluated for yield. Chemical characterization is performed using gas chromatography-mass spectrometry to identify and quantify fatty acid constituents. Physicochemical parameters including acid value, iodine value, peroxide value, and saponification value are determined using standard analytical methods. The invention further includes in vitro antimicrobial assessment of the extracted oil against selected microbial consortia using agar diffusion and minimum inhibitory concentration assays. Additionally, in silico molecular docking of identified fatty acids with selected microbial target proteins is carried out, and correlations between in silico and in vitro results are established using statistical analysis. The disclosed method enables systematic extraction and evaluation of onion seed oil using experimentally supported procedures."
