 note = {Dahlia tuber extract are a good source of inulin, a soluble dietary  fiber, comparable to other inulin-rich foods such as Jerusalem artichoke, chicory and edible burdock. In the present study, the effect of a dahlia tuber extract on sugar tolerance was examined. The dahlia tuber extract showed weak inhibition against α-glucosidases, inhibiting the activity of maltase in hog intestinal mucosa with an IC50 of 73mM vs 1.7 mM for acarbose. Kinetic analysis revealed that the dahlia tuber extract behaved like a mixed non-competitive type inhibitor with a Ki value of 108mM.Oral sugar tolerance tests in healthy rats showed that administration of the dahlia tuber extract along with maltodextrin
suppressed the postprandial increase in blood glucose. The ameliorating effect of the dahlia tuber extract on sugar intolerance in the normal rats was considered to be mainly due to its α-glucosidases inhibitory activity.},
