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.

[ What is claimed is:] [1.] A process for producing a mixture of unripe Rosaceae fruit polyphenols, which comprises:preparing a juice from unripe Rosaceae fruit by pressing or crushing the fruit;contacting the juice with an adsorbent for the fruit polyphenols capable of selectively adsorbing the fruit polyphenol contained in the juice or extract and also capable of releasing the adsorbed polyphenol by the use of an elutant,the adsorbent being selected from the group consisting of a styrene-divinylbenzene type synthetic resin, anion exchange resin, and octadecyl groupchemically bonded silica gel; and eluting the mixture of fruit polyphenols from the adsorbent with anhydrous ethanol.
