[Studies on flavonoid glycosides of Sarcandra glabra].


PMID 18841770

Abstract

To in vestigate the chemical constituents of Sarcandra glabra and obtain a more comprehensive understanding on its effective components. The constituents were isolated by various column chromatographic method and their structures were elucidated by physico-chemical properties and spectroscopic analysis. Five flavonoid glycosides were isolated and identified as kaempferol-3-O-beta-D-glucuronide (1), quercetin-3-O-alpha-D-glucuronide (2), quercetin-3-O-beta-D-glucuronopyranoside methyl ester (3), 5, 7, 4'-trihydroxy-8-C-beta-D-glucopyranosyl flavanone (4), neoastilbin (5), 5-O-caffeoylquinic acid methyl ester (6), 3, 4-dihydroxybenzoic acid (7), isofraxidin (8). Compounds 1-6 were isolated from the genus Sarcandra for the first time. The glucuroide compounds compounds 1-3, were first isolated from the genus Sarcandra.
