New flavonol glycosides from Aconitum burnatii Gayer and Aconitum variegatum L / S. Vitalini, A. Braca, D. Passarella, G. Fico. - In: FITOTERAPIA. - ISSN 1971-551X. - 81:7(2010), pp. 940-947. [10.1016/j.fitote.2010.06.012]
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-(13)--L-rhamnopyranoside
(1), quercetin 3-O--D-glucopyranoside-7-O--D-glucopyranosyl-(13)--L-rhamnopyranoside
(2), quercetin 3-O--D-glucopyranoside-7-O-(6-E-caffeoyl)--D-glucopyranosyl-(13)--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.
