title: New flavonol glycosides from the flowers of Aconitum napellus ssp. tauricum.
abstract: From the methanolic extract of the flowers of A. napellus spp. tauricum four new flavonol glycosides: quercetin 3-O-(6-trans-caffeoyl)-beta-glucopyranosyl-(1-->2)-beta-glucopyranoside-7- O-alpha-rhamnopyranoside (1), kaempferol 3-O-(6-trans-caffeoyl)-beta-glucopyranosyl-(1-->2)-beta- glucopyranoside-7-O-alpha-rhamnopyranoside (2), quercetin 3-O-(6-trans-p-coumaroyl)-beta-glucopyranosyl-(1-->2)-beta- glucopyranoside-7-O-alpha-rhamnopyranoside (3), and kaempferol 3-O-(6-trans-p-coumaroyl)-beta-glucopyranosyl-(1-->2)-beta- glucopyranoside-7-O-alpha-rhamnopyranoside (4), together with the known beta-3,4-dihydroxyphenethyl beta-glucopyranoside were isolated. The structural elucidation of all compounds was deduced on the basis of 1H- and 13C-NMR spectral data, including those derived from 2D-NMR, as well as on HPLC-MS results.
