Highly Oxygenated Flavonoids from Polygonum orientale

Nine highly oxygenated flavonoids, having eight oxygen functional groups at C-3, 3', 4', 5, 5', 6, 7 and 8, were isolated from Polygonum orientale.Of these compounds, seven (1, 2a, 3a, 4, 5a, 6 and 7) are new compounds and the structures were determined on the basis of spectral evidence as 3,3',5,6,7,8-hexamethoxy-4',5'-methylenedioxy-(1), 5-hydroxy-3,3',6,7,8-pentamethoxy-4',5'-methylenedioxy-(2a), 3'-hydroxy-3,4',5,5',6,7,8-heptamethoxy-(3a), 3,3',5,8-tetramethoxy-4',5',6,7-bis(methylenedioxy)-(4), 3'-hydroxy-3,4',5,5',8-pentamethoxy-6,7-methylenedioxy-(5a), 3,3',4',5,5',8-hexamethoxy-6,7-methylenedioxy-(6) and 3',5-dihydroxy-3,4',5',8-tetramethoxy-6,7-methylenedioxyflavone(7a).Keywords---Polygonum orientale; highly oxygenated flavonoids; solvent shift in (1)H-NMR; MS
