Zusammenfassung: | The anti-hyperglycaemic effects of the leaves of Acer pycnanthum K. Koch, and the purification and identification of the active compounds were investigated. Extracts of the leaves showed a potent inhibitory effect on the α-glucosidase in both in vivo and in vitro experiments. The fractionation of the crude extract gave two active compounds, ginnalin B (6-O-galloyl-1,5-anhydro-D-glucitol) and ginnalin C (2-O-galloyl-1,5-anhydro-D-glucitol), by spectroscopic analysis. This is the first report that A. pycnanthum and its constituents may be useful for the prevention or treatment of diabetes mellitus. |
