AGENT FOR IMPROVING GLUCOSE TOLERANCE DISORDER

摘要

An agent for improving glucose tolerance disorder that comprises, as an active ingredient, partition chromatography peak components of an alcoholic extract of gramineous plant seeds, said peak components preferably comprising an alkyl resorcinol (AR) mixture containing multiple kinds of alkyl resorcinols. This mixture preferably contains an AR of general formula (I) wherein R1 is a saturated or unsaturated alkyl group having 15 carbon atoms, an AR of general formula (I) wherein R1 is a saturated or unsaturated alkyl group having 17 carbon atoms, an AR of general formula (I) wherein R1 is a saturated or unsaturated alkyl group having 19 carbon atoms, an AR of general formula (I) wherein R1 is a saturated or unsaturated alkyl group having 21 carbon atoms, an AR of general formula (I) wherein R1 is a saturated or unsaturated alkyl group having 23 carbon atoms, and an AR of general formula (I) wherein R1 is a saturated or unsaturated alkyl group having 25 carbon atoms, each in a specific amount. In general formula (I): R1 represents a saturated or unsaturated alkyl group having 15-25 carbon atoms; and R2 represents a hydrogen atom or a methyl group.
