New flavonol glycosides from Aconitum burnatii Gáyer and Aconitum variegatum L.

From Aconitum burnatii Gáyer and A. variegatum L. three new flavonol glycosides, quercetin 3-O-β-Dglucopyranoside-7-O-(6-E-p-coumaroyl)-β-D-glucopyranosyl-(1→3)-α-L-rhamnopyranoside (1), quercetin 3-O-β-Dglucopyranoside-7-O-β-D-glucopyranosyl-(1→3)-α-L-rhamnopyranoside (2), kaempferol 3-O-β-D-galactopyranoside-7-O-α-L-arabinopyranoside (4), and three known compounds were isolated. Their antioxidant potential was tested.
