Abstract (en)
[origin: US8567412B2] This invention provides for reducing free-radicals from cigarette smoke by using a filter impregnated by an extract of a rosemary plant in oil, containing carnosol, rosmanol, rosmadial, carnosic acid, genkwanin and rosmarinic acid. The extract is obtained by extraction with an alcoholic solvent or an aqueous alcoholic solvent, followed by extraction with a supercritical fluid.
