| 摘要 |
alpha -Glycosyl hesperidin, a novel hesperidin derivative wherein equimolar or more D-glucose residues are bound to hesperidin via the d-bond, is formed by a saccharide-transferring enzyme in a liquid containing hesperidin and alpha -glucosyl saccharide. The alpha -glycosyl hesperidin is easily recovered from the reaction mixture with a synthetic macroporous resin. alpha -Glycosyl hesperidin is superior in water-solubility, substantially tasteless and odorless, free of toxicity, and readily hydrolyzable in vivo into hesperidin and D-glucose to exhibit the physiological activity inherent to hesperidin. Thus, alpha -glycosyl hesperidin is favorably usable in vitamin P-enriching agents, foods, beverages, tobaccos, foods, pet foods, pharmaceuticals for susceptive diseases, cosmetics and plastics. |
