Background : The hypoglycemic effects of mulberry leaves extract were evaluated by comparing the abilities on glucose uptake in C2C12 myotubes and 3T3-L1 adipocyte. Glucose uptake of the extracts were identified to be enhanced by bio-conversion using cellulolytic enzyme like Viscozyme. Methods and Results : The mulberry (Morus alba L) leaves were extracted with 30% ethanol or hot water. The hypoglycemic compounds such as Moracin C and, Quercetin and 1-Deoxynojirimycin were identified from the extracts of mulberry leaves. The extracts were fermented using kinds of celluolytic enzymes, which were vicozyme, pectinase, β-glucosidase and xylanase, in order to increase the contents of hypoglycemic constituents in the extracts. The hypoglycemic effects of the fermented extracts were evaluated by comparing the abilities on glucose uptake in C2C12 myotubes and 3T3-L1 adipocyte. The extracts of mulberry leaves fermented with only Viscozyme were identified to increase glucose uptake in C2C12 myotubes and 3T3-L1 adipocyte by supplement of the concentration of 10 μM extracts, compared to insulin as control. However, bio-conversion effects by other enzymes were not shown in the treatments, suggesting hypoglycemic constituents in the extracts of mulberry leaves can be conversed to more active compounds by cellulolytic enzyme treatment like viscozyme. Conclusion : From the above results, we may suggest that the hypoglycemic constituents in mulberry leaves extracts can be conversed to more active compounds by cellulolytic enzymes.
