Flavonoid Pattern in the Pteridaceae II

Flavonoid Constituents in the Fronds of Adiantum capillus-veneris and A. cuneatum

抄録

Flavonoid glycosides in Adiantum capillus-veneris and A. cuneatum were investigated to see if any relation exists among the flavonoid patterns in the genus Adiantum. Identified flavonoids in A. capillus-veneris fronds were astragalin (kaempferol 3-glucoside), isoquercitrin (quercetin 3-glucoside), kaempferol 3-glucuronide, querciturone (quercetin 3-glucuronide), nicotiflorin (kaempferol 3-rhamnoglucoside) and rutin (quercetin 3-rhamno glucoside), but a flavanone and two flavonols were not identified. Astragalin, kaempferol 3-glucuronide and querciturone were found in A. cuneatum. Therefore these two species have three common flavonoid glycosides.
