Fourteen kinds of amylase inhibitor (AI) were obtained by active carbon column chromatography and other procedures. The molecular weights of the AIs were estimated to be 310-1300 by gel filtration. They seem to have 1-4 glucose residues and one nitrogen per molecule. All the AIs have almost the same inhibitory activity against glucoamylase. High molecular weight AIs have much stronger activity toward α-amylase and phosphorylase α than low molecular weight AIs, but the latter have much stronger inhibitory activity toward sucrase and α-glucosidase than the former. Four kinds of AI were hydrolyzed by β-amylase which changed their inhibitory activities.
