A method for extracting valuable alkaloid materials from plants containing the same comprising slurrying the comminuted plant material in a mixture of water and a cosolvent at a pH of 8.5, adding a nonpolar, water-insoluble, solvent to dissolve the alkaloid, washing the nonpolar phase with acidulated water to convert the alkaloid to the imminium ion or acid salt form, precipitating the alkaloids, and recovering and drying the alkaloid.

Production of high purity alkaloids

A method of extracting benzo-c-phenanthridine alkaloids from plants of the families Papaveraceae, Fumariaceae, and Berberidaceae, comprising grinding the plant, extracting the ground plant with acidulated methanol or acidulated ethanol, precipitating the extract with an acid salt soluble in the solvent used, redissolving the precipitated salt in water, adding sufficient acid to form a precipitate, and collecting the precipitate so formed.

Production of purity benzo-c-phenanthridine alkaloid salts

A method for extracting benzo-c-phenanthridine alkaloids from plants of the families Papaveracease Fumariaciae, and Berberidacae, comprising extracting ground plant material with acidulated methanol precipitating the extract with an acid salt which is soluble in methanol, redissolving the precipitated salt in water, adding sufficient acid to form a precipitate, and collecting the precipitate so formed. The benzo-c-phenanthridine alkaloids have valuable properties as antimicrobials as well as in treating mouth odors, gingivitis, and periodontitis.
