[Eng., ., emet(ic), and suff. -ine (Chem.) (q. v.).] Chem.: An alkaloid, C30H44N2O4, contained in ipecacuanha, from which it is extracted by cold sulphuric acid and water, precipitating, with exce of lime, and treating the precipitate with ether; the ethereal solution is evaporated to dryne , the residue treated with acidulated water, and the emetine precipitated by the addition of ammonia. Emetine forms a crystalline salt with hydrochloric acid. It decomposes ammonium chloride, and gives a bright orange color when a trace of it is added to chlorinated lime, acidified with weak acid. Emetine is extracted from complicated organic matter by chloroform or benzene in an alkaline solution.
