Abstract

PURPOSE: To prepare a crude drug extract containing the effective components in high concentrations, easily, by freeze-thickening the crude drug extract in the presence of the extract residue.
CONSTITUTION: One or more crude drugs (e.g. cassia bark, peony root, jujube fruit, ginger root, ricorice root, etc.) are extracted with an aqueous medium (e.g. water, hydrous alcohol, etc.), and the extract is freeze-thickened in the presence of the extract residue to obtain the objective concentrated extract. The freeze-thickening of the extract is carried out without separating the extract residue from the liquid, by cooling the mixture usually at -5W-20°C and separating the easily separable coarse ice crystals from the extract together with the extract residue by centrifugal separation, etc. The remaining liquid contains highly concentrated crude drug components, and also contains volatile components, heat-unstable components, etc.
