Contribution à l’étude structurale des composés de Centaurea dimorpha

Written by sctunisie no comments

Three extracts from flowers and stems of Centaurea dimorpha showed anti-Giardia, anti-oxydant, anti-inflammatory and anti H.I.V. activities. Two lignans, one alcane and four triterpens have been isolated from flowers and leaves of Centaurea dimorpha (Asteraceae). By means of spectroscopic methods (MS, IR, UV, 1H and 13C NMR and NOE difference sequence), their structures were established as arctigenin, arctigenin-4'-glucoside, tricosane, (β-amyrin, taraxasterol, sitosterol-3-O-β-D-glucoside and poriferasterol.
