Beschreibung
Zusammenfassung:	An .alpha.-amylase activity inhibitor containing as the active ingredient polyphenols which are obtained by extracting guava leaves and/or fruits with one or more solvents selected from among water and hydrophilic solvents, eliminating materials having molecular weight less than 5,000 by ultrafiltration, using hydrophobic chromatography with the use of a packing carrying butyl as the solid phase, eluting under stepwise concentration gradient of a 0.02 mol/L aqueous solution of monosodium dihydrogenphosphate and a 0.02 mol/L aqueous solution of trisodium phosphate at a flow rate of 1 mL/min, and then collecting a fraction recognized as the third single peak in case of measuring the absorbance at 260 nm; an .alpha.-amylase activity inhibitor containing as the active ingredient polyphenols having specific physicochemical properties; and foods and drinks, etc. containing the same.
