[New homoisoflavanones from Polygonatum odoratum (Mill.) Druce].
To study chemical constituents of Polygonatum odoratum (Mill.) Druce, the compounds were separated with column chromatography and HPLC. On the basis of physicochemical properties and spectral data, their structures were confirmed. Nine compounds were isolated and identified as 5,7-dihydroxy-6-methoxyl-8-methyl-3-(2',4'-dihydroxybenzyl)chroman-4-one (1), 5,7-dihydroxy-6-methyl-3-(2',4'-dihydroxybenzyl)chroman-4-one (2), 5,7-dihydroxy-6-methoxyl-8-methyl-3-(4'-methoxybenzyl)chroman-4-one (3), disporopsin (4), chrysoeriol (5), 5,4'-dihydroxy-7-methoxy-6-methylflavone (6), N-trans-feruloyltyramine (7), N-trans-feruloyloctopamine (8), and (+)-syringaresinol (9). Compounds 1-3 are new homoisoflavanones. Compounds 4-9 are isolated from this plant for the first time.
