This study involved the synthesis of epigallocatechin-3-gallate-Iron (II, III) oxide (EGCG- Fe3O4) nanocatalysts by reacting Fe2O3 with EGCG extracted from green tea (Camellia sinensis) aqueous extract. environmentally friendly method was used as an alternative to traditional routes. The EGCG- Fe3O4 were characterised using various techniques, including fourier transform infrared spectroscopy (FTIR), ultraviolet-visible (UV), X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission (TEM), thermogravimetric analysis (TGA), BET Surface area analysis, and vibrating sample magnetometer (VSM). results showed that nanocatalyst absorption peak at 363 nm indicated formation nanocatalyst, while shifted slightly 274 nm, indicating nanocatalyst. conversion final product aliphatic aldehyde alcohol in cotton surface via a solvent free aerobic oxidation EGCG-Fe3O4 confirmed 1H 13C NMR. molecular weight determined mass spectral characterisation (EI-MS), which ion m/z 72.06 (M+, 100%), isobutyraldehyde conforming EI-MS analysis. has been for alcohols textile pharmaceutical industries offers several advantages, use reaction conditions, reduced catalyst concentrations, high yields, affordability, absence solvents, recovery reuse

Vitex negundo Linn, belonging to the verbenaceae family and commonly known as 'Nirgundi', is a significant medicinal plant. This woody, aromatic shrub can grow into small tree typically features 3 or 5 leaves on quadrangular branches. It produces bluish-purple flowers arranged in branched tomentose cymes. In addition its various properties, it reputed have anticonvulsant effects. The objective of this study analyze anti-convulsant effects an ethanolic extract (EEVN) with model Maximum Electroshock-induced Seizure (MES) induction. 30 albino rats, each weighing between 120-150 grams, were divided five groups 6 animals each. Group I administered normal saline (0.5 ml p.o), II received Phenobarbitone (10 mg/kg body weight, i.p), Groups III, IV, V given different dosages EEVN (50, 100, 200 p.o respectively). Convulsions induced all by applying maximal electric shock 150 mA for 0.2 seconds using electro-convulsiometer, 1 hour after administering control, standard, test drugs. onset duration tonic hind limb extension (THLE) percentage protection recorded. MES model, EEVNF at doses 50 mg/kg, 100 significantly (p<0.001) reduces reduced THLE compared standard drug. demonstrated properties shock-induced convulsions experimental animals.
