Flavonoids from Lactuca quercina and L. tatarica

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.
