Abstract: | In this paper, we report studies on morphological, phytochemical, and biological aspects of a population belonging to Aconitum anthora L. Two compounds, quercetin 3-O-((beta-D-glucopyranosyl-(1-->3)-(4-O-(E-p-coumaroyl))-alpha-L-rhamnopyranosyl-(1-->6)-beta-D-galactopyranoside))-7-O-alpha-L-rhamnopyranoside (1) and kaempferol 3-O-((beta-D-glucopyranosyl-(1-->3)-(4-O-(E-p-coumaroyl))-alpha-L-rhamnopyranosyl-(1-->6)-beta-D-galactopyranoside))-7-O-alpha-L-rhamnopyranoside (2), together with two known flavonol glycosides (3-4) were isolated and identified from A. anthora. The antioxidant activity of the four identified flavonoids was screened by three in vitro tests. |
