PROCESS FOR PRODUCING MALLOTUS PHILIPPENSIS COLORANT COMPOSITION AND THE COMPOSITION

摘要

An object of the present invention is to provide a Mallotus philippinensis extract 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 a Mallotus philippinensis plant body, the addition of a base component drastically improves the water solubility of the Mallotus philippinensis extract. 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.
