MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202611111802 A) filed by Vijay Kumar on September 17, 2026, for A Rapid Process For Preparing A Limonoid-Rich Active Fraction From Neem Oil Sediment.
Inventor includes Vijay Kumar.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: The invention relates to a rapid process for preparing a neem-derived limonoid-containing solid fraction from neem oil sediment obtained from neem oil processing. The process comprises adding hexane to neem oil sediment in an amount of approximately two times the quantity of neem cake, subjecting the mixture to mild stirring for approximately 5 minutes followed by approximately 5 minutes of standing at about room temperature, decanting the hexane layer and recovering the solid residue, and drying the residue under fume-hood exhaust for approximately 3 hours at about 30–35°C. The resulting material is characterized for nimbin and azadirachtin by HPLC and HPTLC and may additionally be tested for residual hexane by headspace GC or GC-MS. In the documented batch, limonoid-rich dried material (NC-NT) showed 0.26% azadirachtin and 0.66% nimbin by HPLC and 0.28% azadirachtin and 0.69% nimbin by HPTLC. The process provides a rapid and controllable method for the preparation of a chemically characterized neem-derived solid material.
