PROBLEM TO BE SOLVED: To provide a method for extracting Shikon (root of Lithospermum erythrorhizon) extract free from color clouding and having suppressed odor.
SOLUTION: Shikon extract is extracted from Shikon by using liquid carbon dioxide, extracting at a temperature below the critical temperature of carbon dioxide under pressure of &ge1 MPa and giving a Shikon extract having specific absorbance (E
1% 1cm ) of &ge120. The obtained Shikon extract is free from color clouding and has suppressed odor and, accordingly, is suitable as a skin care preparation, especially a preparation containing 0.0001-1 wt.% Shikon extract.COPYRIGHT: (C)2007,JPO&INPIT
