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