Formation of Di-D-fructose Anhydride III from Inulin by the Root of Lycoris radiata Herbert

Abstract

Di-D-fructose anhydride III has been isolated from inulin digested by a root-homogenate of Lycoris radiata. Identification of the compound was based on crystallization, mp, mixed mp, specific rotation and IR spectrum. The results strongly suggested the existence of inulin fructotransferase activity in the root of Lycoris radiata.
