Phytochemistry. 2001 Jun;57(4):543-6. doi: 10.1016/s0031-9422(01)00102-9.

Abstract

Three flavonol glycosides quercetin 7-O-(6-trans-caffeoyl)-beta-glucopyranosyl-(1-->3)-alpha-rhamnopyranoside-3-O-beta-glucopyranoside (1), kaempferol 7-O-(6-trans-caffeoyl)-beta-glucopyranosyl-(1-->3)-alpha-rhamnopyranoside-3-O-beta-glucopyranoside (2), and kaempferol 7-O-(6-trans-p-coumaroyl)-beta-glucopyranosyl-(1-->3)-alpha-rhamnopyranoside-3-O-beta-glucopyranoside (3), together with the known beta-3,4-dihydroxyphenethyl beta-glucopyranoside, were isolated from the flowers of Aconitum napellus subsp. neomontanum. Their structures were elucidated by spectroscopic methods, including 2D NMR spectral techniques.
