PURPOSE:To enable the economical concentrating extraction of a component within a short time by using a small amount of a solvent, by performing the componential extraction of a stock material consisting of a plant and a crude drug by water or an org. solvent after said stock material is comminuted in a pressure reduced container by the rotation of a mixer blade. CONSTITUTION:In extracting the components of a stock material consisting of a plant and a crude drug with water or an org. solvent, said stock material is comminuted by rotating a mixer blade simultaneously with the pressurization or pressure reduction of a container and the extractive concentration of the comminuted stock material is performed. By using thus operated component concentrating extractor, the extractive concentration can be performed within a short time with a small amount of the solvent.
