Abstract

The methanol extract of kiwifruit leaf suppressed the postprandial blood glucose level after an oral administration of soluble starch or sucrose in mice. The mechanism of action is proposed to be due to the α-amylase-inhibiting activity in the 90% aqueous methanol fraction and α-glucosidase-inhibiting activity in the n-buthanol fraction, based on the results of in vitro experiments.
