MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202611026920 A) filed by Rashmi Sumbria; Manjit Kaur; Vanshika; Shakshi Thappa; Sumiksha Sharma; Ravneet Kaur; Anand Kumar; Nishan Sarngal; Amisha Devi; and Ansh Mahajan, Pathankot, Punjab, on March 7, for 'a method for phytochemical extraction, evaluation, and anticonvulsant screening of selected leaf extract.'
Inventor(s) include Rashmi Sumbria; Manjit Kaur; Vanshika; Shakshi Thappa; Sumiksha Sharma; Ravneet Kaur; Anand Kumar; Nishan Sarngal; Amisha Devi; and Ansh Mahajan.
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 present invention relates to a method for the preparation, formulation, phytochemical characterization, and evaluation of the anticonvulsant activity of Albizia procera leaf extracts using validated animal seizure models. The method comprises collection and processing of leaf material followed by successive solvent extraction using petroleum ether (60-80 C), ethyl acetate, and ethanol in a Soxhlet apparatus for a defined extraction period. The obtained extracts are concentrated, dried, and subjected to preliminary qualitative phytochemical screening to identify bioactive constituents including alkaloids, flavonoids, saponins, tannins, sterols, carbohydrates, and glycosides. The anticonvulsant potential of the extracts is evaluated using established in vivo models such as Maximum Electroshock (MES)-induced seizures and Pentylenetetrazole (PTZ)-induced seizures. Seizure parameters including onset, duration, tonic hind limb extension, clonic convulsions, and percentage protection are assessed and statistically analyzed. The disclosed method provides a systematic and reproducible approach for investigating plant-derived anticonvulsant agents and supports the development of phytopharmaceutical compositions with potential neuroprotective and therapeutic applications."
