Abstract
Five kaempferol glycosides in the fronds of Asplenium scolopendrium were isolated . The structures of three novel flavonol glycosides were determined to be kaempferol 3-O -β-D -glucopyranosyl-( 1→3 )-β -D -(2 -O -caffeoyl)glucopyranoside 7 -O -α -L -rhamnopyranoside , kaempferol 3 -O -β -D -glucopyranosyl-(1→3 )-β -D -glucopyranoside 7 -O -α -L -rhamnopyranoside and kaempferol 3 -O -(2 -O -caffeoyl)-β -D -glucopyranoside 7 -O -α -L -rhamnopyranosideby means of spectral data (FAB-M S, 1H-1H, 1H -13C COSY and 1H-13C long range COSY), respectively.
