Three flavonol glycosides quercetin 7-O-(6-trans-caffeoyl)-β-glucopyranosyl-(1→3)-α-rhamnopyranoside-3-O-β-glucopyranoside (1), kaempferol 7-O-(6-trans-caffeoyl)-β-glucopyranosyl-(1→3)-α-rhamnopyranoside-3-O-β-glucopyranoside (2), and kaempferol 7-O-(6-trans-p-coumaroyl)-β-glucopyranosyl-(1→3)-α-rhamnopyranoside-3-O-β-glucopyranoside (3), together with the known β-3,4-dihydroxyphenethyl β-glucopyranoside, were isolated from the flowers of Aconitumnapellus subsp.
