An object of the present invention is to provide a carbohydrate-derived energy supplying agent having slow digestibility and sustained digestibility functions. According to the present invention, there is provided a slowly digestible, sustained-type energy supplying agent comprising a saccharide composition which satisfies the following (A), (B), (C), and (D): (A) a percentage of &#x3b1;-1,6 bonds relative to all glycosidic bonds is 60% or more; (B) a content of saccharides having a degree of polymerization of 1 and 2 relative to all saccharides is 9 mass % or less; (C) a content of saccharides having a degree of polymerization within a range of 3 to 30 relative to all saccharides is 41 mass % or more; and (D) a content of saccharides having a degree of polymerization of 31 or more relative to all saccharides is 50 mass % or less.

Slowly digestible, sustained-type energy supplying agent

There are disclosed a compound represented by the following general formula I wherein R represents a cyclic hydrocarbon group, and n represents 0 (zero) or an integer not less than 1, as well as &bgr;-glucosidase inhibitor, aromatic substance formation inhibitor, plant life lengthening agent, each of which contains at least one of compound represented by the aforementioned general formula I as an active ingredient, and plant or a part thereof in which formation of aromatic substance is inhibited by the aforementioned aromatic substance formation inhibitor. The present invention provides a novel compound that has &bgr;-glucosidase inhibition activity and can easily be produced in an industrial process, as well as a &bgr;-glucosidase inhibitor and aromatic substance formation inhibitor each containing such a novel compound as an active ingredient, and plant or part thereof in which the formation of aromatic substances is inhibited by the aforementioned aromatic substance formation inhibitor.

Cycolalkylated B-glucoside

Cycloalkylated beta-glucoside

Galactosyl maltooligosaccharide derivatives represented by formula (1): ##STR1## wherein at least one of X.sub.1 and X.sub.2 represents a galactosyl group and the other represents a hydrogen atom, R represents a hydrogen atom or a substituted or unsubstituted phenyl group, and n is an integer of from 2 to 5. The derivatives are prepared by reacting a sugar with a galactosyl group with a maltooligosaccharide represented by formula (2): ##STR2## R represents a hydrogen atom or a substituted or unsubstituted phenyl group, and n is an integer of from 2 to 5; in the presence of .alpha.-galactosidase or .beta.-galactosidase. The derivatives are used for measurement of .alpha.-amylase activity.
