Abstract
Abstract PURPOSE:To obtain diglucosyl-beta-cyclodextrin nearly comparable in an inclusion power to well-known beta-cyclodextrin and markedly excellent in solubility, by allowing glucoamylase to act upon dimaltosyl-beta-cyclodextrin. CONSTITUTION:The titled compound is obtained by allowing glucoamylase to act upon dimaltosyl-beta-cyclodextrin. This reaction is preferably carried out at 30-60 deg.C and a pH in the range of 3.5-6.5. The obtained diglucosyl-beta- cyclodextrin is a white powder having a molecular formula of C54H90O45, a MW of 1,459 (mass spectrometry), a m.p. of 277.5 deg.C and easy solubility in water.
