IPC: A61K36/00
Filed: 1986-12-04
Abstract: PURPOSE:To mold a powdered crude drug in a form of ready internal use without losing active ingredients, by pressurizing powdered Japanese or Chinese crude drug into a sheet form without adding water or an organic solvent, crushing and sizing the molded powder to a given size. CONSTITUTION:A Japanese or Chinese crude drug is cut to a size of about 1cm, put in a hermetically sealed container, frozen with injected liquid nitrogen and powdered in a pulverizer to provide a powdered Japanese or Chinese crude drug having 20-50mu size. The powder is then pressurized under 80-100kg/cm<2> pressure using a pressure roller and molded into a sheet form having 1.0-1.5mm thickness. In the process, pressurizing is carried out without using water or an organic solvent. The obtained sheet material is further crushed and sieved into granules having 30-150 mesh size or fine particles of 180-500mu size to afford the aimed substance. Essential oil ingredients or trace amounts of water in cells ooze out simply by pressurizing to provide a binder and molding can be carried out. Since water or organic solvent is not used, drying steps are omitted and crude drugs equal to those of original crude drugs are obtained without deterioration or denaturation.
