Abstract
From the chloroformic fraction of the ethanolic extract of the aerial parts of Asteriscus pygmaeus (DC.) Coss & DR (Syn. Odontospermum Pygmaeum) five flavonoids were isolated and identified as apigenin, luteolin-7-O-methylether, luteolin, quercetin-3-O-methylether and quercetin. Apigenin 7-O-glucoside, luteolin 7-O-glucoside and luteolin 7,4'-di-O-glucoside were isolated from the ethyl acetate and butanol fractions. Their structures were established by physical, chemical and spectral methods.
