A new flavone glycoside from Selaginella moellendorffii Hieron.

From the ethanol extract of Selaginella moellendorffii Hieron., a new flavone O-glycoside and three known flavone C-glycosides have been isolated and identified as 5-carboxymethyl-4'-hydroxyflavone-7-O-beta-D-glucopyranoside1,6,8-di-C-beta-D-glucopyranosylapigenin 2, 6-C-beta-D-glucopyranosyl-8-C-beta-D-xylopyranosyl apigenin 3, 6-C-beta-D-xylopyranosyl-8-C-beta-D-glucopyranosylapigenin 4, respectively. Their structures were elucidated by spectroscopic methods. (c) 2008 Ke Li Chen. Published by Elsevier B.V. on behalf of Chinese Chemical Society. All rights reserved.
