Polyphenolic compounds in Scopolia caucasica Kolesn. ex Kreyer (Solanaceae)

The qualitative and quantitative determinations of coumarins, phenolic acids and flavonoids in the leaves and underground parts of Scopolia caucasica using paper chromatography and HPLC methods were described. From the leaves of this plant, kaempferol 3-O-(2-glucosyl)-galactoside-7-O-glucoside, kaempferol 3-O-(2-glucosyl)-galactoside and quercetin 3-O-glucoside were isolated and identified by spectroscopic methods (UV, 1H- and 13C-NMR).
