Flavonoids from Goodyera schlechtendaliana

A flavonol glycoside, 3-[[6-O-(6-deoxy-alpha-L-mannopyranosyl)-beta-D-gluco pyranosyl]oxi]-5-7- dihydroxy-8-[(4-hyddroxy-3,5-dimethoxyphenyl)methyl]-2- (3,4-dihydroxypheny)4H-1-benzopyran-4-one, trivially named goodyerin, was i solated from the whole plant of Goodyera schlechtendaliana, along with thre e known flavonoids, rutin, kaempferol-3-O-rutinoside and isorhamnetin-3-O-r utinoside. The structures were established by spectroscopic analysis. (C) 2 000 Elsevier Science Ltd. All rights reserved.
