摘要

Previous investigations on the flavonoids of the genus Dryopteris have led to the identification of ten flavonol glycosides based on kaempferol and quercetin, two flavanone O-glycosides (based on naringenin and eriodictyol) and three C-glycosylflavones (vitexin, vitexin 7-O-glucoside and orientin) by Hiraoka (Biochem. Syst. Ecol. 6:171-175. 1978) in eighteen Dryopteris species and to the identification of 3-desoxyanthocianins (mainly as apigenidin and luteolinidin 5-O-glucosides] in red sori of Dryopteris erythrosora (Eat.) Kuntze by Harborne (Phytochemistry 5:589-600. 1966). In addition, kaempferol 7-O-(6"-succinylglucoside) was found in four Dryopteris species and an unusual flavonoid (3,7,3',4'-tetrahydroxy-5-acetoxyflavan having the methyl group of acetoxyl further bounded to C-4 of C-ring) was isolated from Dryopteris filix-mas (L.) Schott as shown in a review by Markham (pp. 427-468, in J.B. Harborne ed., The Flavonoids, Advances in Research since 1980. Chapman and Hall, London and New York. 1988). Ten flavonoids (seven flavonol glycosides based on kaempferol and quercetin including a new compound identified as kaempferol 3-O-(acetylrutinoside) and three flavonoid aglycones (apigenin, kaempferol and quercetin)) have been found recently in Dryopteris villarii (Bell.) Woynar by Imperato (Amer. Fern J. 96:93-95. 2006).
