Abstract

Four flavonoids were isolated from the aerial parts of Euphorbia ebracteolata. On the basis of chemical and spectroscopic evidence, the structures of these compounds were established as $quercetin-3-O-{\beta}-D-glucoside$(isoquercitrin)(I), quercetin-3-O-rutinoside(rutin)(II), kaempferol-3-O-rutinoside(III) and $quercetin-3-O-(2'-O-galloyl)-{\beta}-D-glucoside$(IV) which was the main flavonoidal component in this plant. The isolation of flavonoids from E. ebracteolata is the first example.
