The invention discloses a method for extracting an alpha-amylase inhibitor from lotus seed dregs. The lotus seed processing by-product, namely, lotus seed dregs, is taken as the raw material for preparing the alpha-amylase inhibitor; the alpha-amylase inhibitor finished product is obtained by carrying out digestion on the lotus seed dregs, as well as carrying out crushing, hydrolyzing, centrifuging, enzyme deactivation, salting out, dissolution and freeze-drying. The process has the main advantages that the processing by-product of lotus seeds is effectively utilized, the extraction process is simple, the product is non-toxic and safe, as well as high in purity, and strong in inhibitory activity, the extraction yield is improved to 2.36% from the previous 1.45% (the extraction yield is the percentage of the dry weight of the product obtained by extraction accounting for the total weight of the raw materials), through the measurement by adopting the 3,5-dinitrosalicylic acid method, the highest inhibition rati
