Abstract
A composition including a strawberry-derived polyphenol highly effective for oral administration or external use. A composition for oral administration or external use is obtained by subjecting a hot water extract of strawberry to adsorption chromatography using an aromatic synthetic absorbent, removing the fractions passing through the column and fractions eluted with water, and then eluting with a 5 to 60% aqueous ethanol solution.
