Abstract

Six flavonol glycosides, compounds 1-3 from A. burnatii Gáyer and 4-6 from A. variegatum L., were obtained from their aerial parts methanol extracts. The identified structures were quercetin 3- O--D-glucopyranoside-7-O-(6-E-p-coumaroyl)--D-glucopyranosyl-(13)--L-rhamnopyranoside (1), quercetin 3-O--D-glucopyranoside-7-O--D-glucopyranosyl-(13)--L-rhamnopyranoside (2), quercetin 3-O--D-glucopyranoside-7-O-(6-E-caffeoyl)--D-glucopyranosyl-(13)--Lrhamnopyranoside (3), kaempferol 3-O--D-galactopyranoside-7-O--L-arabinopyranoside (4), quercetin 3-O--D-glucopyranoside (5), and kaempferol 3-O--D-glucopyranoside (6). Compounds 1, 2 and 4 were isolated for the first time. The antioxidant potential of the methanol extracts and pure compounds was tested with different assays.
