Six flavonol glycosides, compds. 1-3 from A. burnatii Gayer and 4-6 from A. variegatum L., were obtained from their methanol exts. of aerial parts. The identified structures were quercetin 3-O-β-D-glucopyranoside-7-O-(6-E-p-coumaroyl)-β-D-glucopyranosyl-(1 → 3)-α-D-rhamnopyranoside (1), quercetin 3-O-β-D-glucopyranoside-7-O-β-L-glucopyranosyl-(1 → 3)-α-L-rhamnopyranoside (2), quercetin 3-O-β-D-glucopyranoside-7-O-(6-E-caffeoyl)-β-D-glucopyranosyl-(1 → 3)-α-L-rhamnopyranoside (3), kaempferol 3-O-β-D-galactopyranoside-7-O-α-L-arabinopyranoside (4), quercetin 3-O-β-D-glucopyranoside (5), and kaempferol 3-O-β-D-glucopyranoside (6). Compds. 1, 2 and 4 were isolated for the first time. The antioxidant potential of the methanol exts. and pure compds. was tested with different assays.
