Abstract
From aerial parts of Lactuca quercina L. and Lactuca tatarica C. A. Meyer six flavonoids were isolated using different chromatographic techniques. Of these, three compounds, apigenin, luteolin and quercetin-3-O-β-glucopyranoside, were found in both species, two compounds, apigenin-7-O-β-glucopyranoside and kaempferol-3-O-β-glucopyranoside, originated from the latter, and one compound, luteolin-7-O-β-glucopyranoside, from the former.
