(57) [Problem] To provide a new use of a specific component derived from banaba, specifically, a new use based on the inhibitory activity of α-amylase. SOLUTION: The present inventors have found excellent α-amylase inhibitory activity of baroneic acid obtained by separating a banaba extract by liquid-liquid partitioning and column chromatography, etc., and based on such knowledge, a sugar containing baroneic acid as an active ingredient. We propose a quality digestive enzyme inhibitor. Since α-amylase is an enzyme that cleaves α-1,4 bonds of starch and glycogen in particular, by inhibiting their digestion and absorption, It can suppress the rapid rise of postprandial blood sugar level and suppress the secretion of insulin, and is effective in preventing and treating diabetes and obesity. |
