Abstract
Process for the production of usnic acid, characterized by extracting certain species of moss with acetone, concentrating the acetone extract to precipitate the crude usnic acid, washing the precipitate with a water-soluble alkanol and then with an aliphatic hydrocarbon solvent to dissolve and eliminate the impurities of the same, finally crystallizing the usnic acid from solution in acetone.
