In the reported fumigation bioassays, pulegone is a most toxic monoterpene. Therefore, the eco-friendly conversion of pulegone to high value compounds viz. menthone and iso-menthone is commercially important. Now, the present claim is related to an eco-friendly process for the selective conversion of pulegone of this essential oil to menthone and iso-menthone without affecting the other major compounds 10287527 An eco-friendly process for the isolation of biopolymers from agricultural residues PK Rout, AD Nannaware, O Prakash, R Rajasekharan USA/10287527/ Agricultural residues (biomasses) have come-up as potential valuable renewable resources for transformation into many bio-products. To achieve this goal, the isolation of major biopolymers in their purest form through an economical process is demanded for synthesis of the target fine chemicals without impurities. However, the difficulty of fractionating the biomass into cellulose, hemicellulose and lignin by a simple method has greatly limited their isolation from agricultural residues. Also, the lipids and waxes present on the surface of the agricultural residues protect it from external chemical and microbial agents. To overcome this issue, the lipids and waxes have been isolated from the biomass through two step organic solvents extraction. Thereafter lignin, hemicellulose and cellulose are isolated successively from the de-waxed biomass. IN202311001655 Multifunctional decentralized mobile solar distillation unit for essential oil extraction AD Nannaware, PK Rout, CS Chanotiya, MK Gupta, S Singh, AV Deorankar, R Verma India/IN202311001655/ A new design for multifunction decentralized mobile solar hybrid distillation unit with hydraulic trolley that aids in effective trapping of solar energy through solar panel structure fitted over the hydraulic trolley for generation of steam to carry out the distillation of aromatic crops to obtain the essential oils. The solar panel mounted over the mobile tractor hydraulic trolley having foldable hydraulic solar panel structure that can move the solar panel structure in both directions to a position at 24 degree angle to capture solar energy and generates steam. Alternatively, this distillation process can run without solar energy in particular night time using direct biomass burning. Hence this hybrid distillation unit has advantage over the existing process.
