Abstract
Disclosed are (1) a novel galactosyl-cyclodextrin having a galactosyl group as bonded to the hydroxyl group of the glucosyl group of a cyclodextrin via an .alpha.-bond and a method of producing said galactosyl-cyclodextrin; (2) a novel galactosyl-cyclodextrin having a galactosyl group as bonded to the hydroxyl group of the glucosyl group of a cyclodextrin via a .beta.-bond and a method of producing said galactosyl-cyclodextrin; and (3) a novel mannosyl-cyclodextrin having a mannosyl group as bonded to the hydroxyl group of the glucosyl group of a cyclodextrin via an .alpha.-bond and a method of producing said mannosyl-cyclodextrin. The new branched cyclodextrins are expected to be widely useful in various fields of drug industry, food industry and cosmetic industry.
