Abstract
From the methanol extract of the wood of Mangifera gedebe (Anacardiaceae), we had isolated a new secondary metabolite named gedebic acid (1) and six known compounds (2–7). Their chemical structures were determined by spectroscopic methods as well as comparing with data in the literature. All compounds were tested for α-glucosidase inhibitory activity. Compounds 4–7 showed more potent inhibitory activity, with IC50 values ranging from 45.3 to 142.6 μM, than that of a positive control acarbose (IC50, 214.5 μM).
