Chemical constituents with antisepsis activity from the rhizomes of Polygonatum odoratum

Chemical Constituents of the Genus Polygonatum and their Role in Medicinal Treatment

“…The structures of some of the isolated flavonoids (32-43) are shown in Figure 6. The homoisoflavones, 5,7-dihydroxy-4′-methoxy-6,8-dimethylhomoisoflavone (44), 4′,5,7-tri-hydroxy-6,8-dimethylhomoisoflavone (45), 4′,5,7-trihydroxy-6-methyl-8-dimethoxyhomoisoflavone (46), 4′,5,7-trihydroxy-6-methylhomoisoflavone (47) and 5,7-dihydroxy-4′,8-dimethoxy-6-methylhomoisoflavone (48) were also isolated from the root of P. odoratum and their structures determined by IR, EI-MS and NMR ( Figure 7) [35,37]. These compounds were tested for their antimicrobial activity against four bacterial and six plant pathogenic species [37].…”

“…Homoisoflavones and flavonoid glycosides have been isolated from Polygonatum species, including 4′, 7-dihydroxy-3′-methoxyisoflavone and isoliquiritigenin from the root of P. kingianum [7,35,36]. The structures of some of the isolated flavonoids (32)(33)(34)(35)(36)(37)(38)(39)(40)(41)(42)(43) are shown in Figure 6.…”
