Abstract
A new C-benzylated flavone, uvariaruflavone (1), along with 13 known compounds (2-14) were isolated from the twig and leaf extracts of Uvaria rufa Blume. Their structures were established by extensive spectroscopic methods. Flavones (5-8) and cyclohexene (10) were isolated from U. rufa for the first time. Most of the isolated compounds were evaluated for their α-glucosidase and α-amylase inhibitory activities. Of these, uvariaruflavone (1) showed the highest α-glucosidase inhibitory activity with an IC50 value of 44.3 µM, while ferrudiol (12) displayed the highest α-amylase inhibitory activity with an IC50 value of 73.5 µM.
