    摘要: The present invention provides a fruit polyphenol obtained by subjecting unripe fruits of Rosaceae to pressing and/or extraction and then purifying the resulting juice or extract. The present invention further provides an antioxidant, a hypotensive agent, an antimutagenic agent, an antiallergic agent and an anticariogenic agent each comprising, as an effective component, a fruit polyphenol obtained by subjecting unripe fruits of Rosaceae to pressing and/or extraction and then purifying the resulting juice or extract. The fruit polyphenol of the present invention has various physiological activities, for example, an antioxidative activity, an ACE-inhibiting activity, an antimutagenic activity, a hyalulonidase-inhibiting activity and a GTase-inhibiting activity.

    摘要: The present invention relates to a process for purifying dimeric to pentameric proanthocyanidin oligomers which comprises extracting the proanthocyanidin oligomers from raw materials containing the proanthocyanidin oligomers or crude purification products therefrom by solid-liquid extraction using methyl acetate as a liquid phase; a process for purifying dimeric to pentameric proanthocyanidin oligomers which comprises pretreating with an enzyme for hydrolysis raw materials containing the proanthocyanidin oligomers, crude purification products therefrom, or a solution containing one of these; and a process for purifying dimeric to pentameric proanthocyanidin oligomers with a uniform polymerization degree which comprises separating and purifying the proanthocyanidin oligomers by polymerization degree from raw materials containing the proanthocyanidin oligomers or crude purification products there from by normal phase silica gel liquid chromatography using as a mobile phase a single solvent or a mixed solvent of two or more solvents selected from the group consisting of an ester solvent, a ketone solvent, a hydrocarbon solvent, an ether solvent and an alcohol solvent.
