Flavonoids from Camptosorus sibiricus Rupr.
Three new flavonol glycosides, kaempferol-3-O-(6-trans-caffeoyl)-beta-D-glucopyranosyl-(1 --> 2)-beta-D-glucopyranoside (1), kaempferol-3-O-(6-trans-caffeoyl)-beta-D-glucopyranosyl-(1 --> 2)-beta-D-glucopyranoside-7-O-beta-D-glucopyranoside (2), and kaempferol-3-O-(6-trans-p-coumaroyl)-beta-D-glucopyranosyl-(1 --> 2)-beta-D-glucopyranoside-7-O-beta-D-glucopyranoside (3), were isolated from the aerial part of Camptosorus sibiricus. Their structures were elucidated by spectroscopic methods, including 2D NMR spectral techniques.
