Abstract
An object of the present invention is to provide aextract containing readily water soluble rottlerin. A further object of the present invention is to improve convenience at production steps in a method for producing such an extract, by avoiding the staining of filters and/or pipes during extraction and filtration to reduce washing costs, or by facilitating the introduction of freeze drying and so on. When a dye extract is extracted with water and alcohol from aplant body, the addition of a base component drastically improves the water solubility of theextract. This improves extraction rates of rottlerin, facilitates washing in the production and the pulverization of the extract, and also improves the water solubility of the obtained extract.
