Effects of polyphenolics, anthocyanin dyes and caffeic aid-derivatives prepared from sweetpotato on sweetpotato b-amylase were investigated for its industrial utilization. Crude extract of anthocyanin dyes did not inhibit b-amylase activity at a concentration of 2.0 mg/ml reaction mixture. In caffeoyl acid-derivatives, 3,4-dicaffeoyl-quinic acid had no inhibitory effect at a concentration of 2.0 mg/ml. Caffeic acid, chlorogenic acid, and 3,5-dicaffeoyl-quinic acid showed the inhibitory activity of about 20% against b-amylase at the same concentration.}, pages = {7--12}, title = {サツマイモβ-アミラーゼに及ぼすポリフェノール類の影響}, volume = {30}, year = {2014}, yomi = {キド, メグミ and サンタンダ, シオリ and クラタ, リエ and テラハラ, ノリヒコ and ヨシモト, マコト} }
