Abstract: The extract of Vicia faba beans is prepared by soaking beans in distilled water overnight and then boiling in a water bath to reduce the volume of aqueous extract, which is then homogenized and filtered. The filtrate is concentrated to a smaller volume, lyophilized, and powdered. The lyophilized powder is extracted with hexane to remove oils and lipids. The oil-free lyophilized powder is dissolved in ethanol solvent and extracted for eight hours under reflux, and filtered. The volume of ethanol is reduced by a rotary evaporator, and a first off-white precipitate (sample A-1) is collected, washed with ethanol, and dried at 80° C. Mass spectrometry shows a molecular weight of 200.16447 g mol?1, and an empirical formula of C9H16N2O3 is assigned. Intraperitoneal injection of mice with 50 mg/kg of A-1 twenty minutes prior to injection with strychnine protected the mice from strychnine-induced convulsions to the same extent as phenobarbitone (phenobarbital).

Abstract: The method for coating a substrate with silver nanoparticles includes reducing a silver nitrate solution with an ethanol extract of the traditional Indian medicinal plant (Curcuma Longa L.), a naturally abundant antioxidant, to form a final solution, and contacting the final solution with the substrate to provide the silver nanoparticle coating. Formation of the silver nanoparticle coating on the substrate can be determined when a mirror in the final solution is observed. The thickness of the coating layer can be less than 125 nm. The coated substrates can be highly conductive.
