Two previously unreported rotenoids, berectones A and B (1 and 2), along with four known compounds, 3,3',4'-tri-O-methylellagic acid (3), kaempferol (4), 7,4'-dihydroxy-8-methoxyisoflavone (5), and trans-N-caffeoyltyramine (6) were isolated from the… Click to show full abstract
Two previously unreported rotenoids, berectones A and B (1 and 2), along with four known compounds, 3,3',4'-tri-O-methylellagic acid (3), kaempferol (4), 7,4'-dihydroxy-8-methoxyisoflavone (5), and trans-N-caffeoyltyramine (6) were isolated from the aerial parts of Boerhavia erecta. The structures of all isolated compounds were fully characterized using spectroscopic data, as well as comparison with the previous literature. Compound 6 exhibited the strongest inhibitory activity toward α-glucosidase with IC50 value of 4.74 µM.
