DIE FLAVONOLGLYCOSIDE VON EUPHORBIA HELIOSCOPIA, E. STRICTA, E. VERRUCOSA und E. DULCIS

Abstract

Five different flavonoid glycosides were isolated and identified from four species of the Euphorbiaceae. Quercetin–3–β-glucoside, quercetin–3–β-galactoside and quercetin–3–β-galactoside–6"-gallate from Euphorbia dulcis; quercetin–3–β-galactoside and quercetin–3–β–galactoside–2"–gallate from E. verrucosa; quercetin–3–β–glucoside, quercetin–3–β–galactoside and quercetin–3–β–galactoside–2"-gallate front E. helioscopia; quercetin–3–β–galactoside and quercetin–3–β–arabinoside from E. stricta.
