Abstract
271,492. Chemische Fabric auf Actien vorm. E. Schering. May 20, 1926, [Convention date]. Medicines for internal use.-Substances similar to the hormones extracted from animal germ glands, placenta &c., are obtained from vegetable organisms by extraction with an organic solvent, concentrating the extract and treating with water or a water-miscible organic solvent and finally extracting the solution or suspension so obtained, or the residue from its evaporation, with ether. According to examples (1) rhubarb or apples are extracted with ethyl or methyl alcohol and the solution, after repeated concentration and treatment with alcohol to precipitate impurities, is evaporated to dryness and the residue extracted with ether; (2) lily of the valley buds or potatoes are comminuted, dried, and extracted with ether in a Soxhlet apparatus and the residue of the ethereal solution is suspended in water and the suspension extracted with ether. Specifications 6019/08 and 18414/12 are referred to. The Specification, as open to inspection under Sect. 91 (3) (a) describes also the treatment of cherries according to examples (1) above, includes further examples according to which (1) parsley root is extracted with methyl alcohol, the solution is evaporated to dryness and the residue dissolved in water and the aqueous solution extracted with ether; (2) yeast free from albumen, obtained by the process of Buchner and Gruber, is extracted with ether, the solution evaporated, the residue extracted with acetone, and after evaporation of the acetone the residue extracted with ether; (3) and a mixture of moist yeast and water is extracted by pressure and the juice extracted with ether, evaporated and purified by repeated solution in ether and acetone: and relates generally to the treatment of plants by any method similar to those employed for obtaining the hormones from animal organs. This subject-matter does not appear in the Specification as accepted.
