Granted: 1999-06-15
Abstract: alpha -Glycosyl naringin, a novel naringin derivative wherein equimolar or more D-glucose residues are bound to naringin via the alpha -bond, is formed by a saccharide-transferring enzyme in a liquid containing naringin and  alpha -glucosyl saccharide. The alpha -glycosyl naringin is easily recovered from the reaction mixture with a synthetic macroporous resin.  alpha -Glycosyl naringin, which retains the bitterness inherent to naringin, is superior in water-solubility, free of toxicity, and readily hydrolyzable in vivo into naringin and D-glucose to exhibit the physiological activity inherent to naringin. Thus,  alpha -glycosyl naringin is favorably usable in vitamin P-enriching agents, foods, beverages, tobaccos, foods, pet foods, pharmaceuticals for susceptive diseases, cosmetics and plastics. <IMAGE>
