MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202611024774 A) filed by Prof. Sumita Kachhwaha; Neelam Meena; Dr. Ashutosh Pathak; and Prof. Shanker Lal Kothari, Jaipur, Rajasthan, on March 2, for 'a plant based method of enhancing pharmacologically important secondary metabolites in tagetes erecta l..'
Inventor(s) include Prof. Sumita Kachhwaha; Neelam Meena; Dr. Ashutosh Pathak; and Prof. Shanker Lal Kothari.
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 plant-based method for enhancing the accumulation of pharmacologically important secondary metabolites through seed nano-priming. The method comprises treating seeds with metal oxide nanoparticles, such as zinc oxide nanoparticles (ZnONPs) or silicon dioxide nanoparticles (SiO2NPs), followed by germination under controlled in vitro conditions. Seed-stage nano-priming induces sustained modulation of metabolic pathways during plant development, resulting in enhanced accumulation of secondary metabolites in plant tissues. In particular embodiments, the method increases the accumulation of flavonoids and sterols, including naringenin and stigmasterol, or biosynthetically related derivatives thereof, in Tagetes erecta. The method involves a single seed-stage intervention without subsequent application of phytohormones and elicitors. The invention provides a reproducible, scalable, and sustainable approach for producing bioactive plant metabolites suitable for pharmaceutical, nutraceutical, and other industrial applications."
