title: Flavonoids from Goodyera schlechtendaliana.
abstract: A flavonol glycoside, 3-[[6-O-(6-deoxy-alpha-L-mannopyranosyl)-beta-D- glucopyranosyl]oxi]-5,7-dihydroxy-8-[(4-hydroxy-3,5-dimethoxyphenyl)meth yl]- 2-(3,4-dihydroxypheny)-4H-1-benzopyran-4-one, trivially named goodyerin, was isolated from the whole plant of Goodyera schlechtendaliana, along with three known flavonoids, rutin, kaempferol-3-O-rutinoside and isorhamnetin-3-O-rutinoside. The structures were established by spectroscopic analysis.
