The aim of this study was to determine the inhibitory effect of powdered Morus australis leaves on postprandial elevation of blood glucose. First, we evaluated the functionality of the powdered leaves. Second, we examined the inhibitory effect of the powdered leaves on blood glucose elevation in healthy volunteers after administrating sucrose. Although 1-deoxynojirimycin content was lower and the median inhibitory concentration against sucrase was higher for the powdered leaves than for the raw leaves, the powdered leaves retained sucrase inhibitory activity. In addition, ingestion of the powdered leaves suppressed sucrose-induced elevation of blood glucose and insulin levels. Thus, we conclude that powdered M. australis leaves have an inhibitory effect on postprandial elevation of blood glucose.
