The volatile compounds from various parts of Echinops ilicifolius (Compositae) such as flowers, leaves and roots obtained by hydrodistillation (HD) and headspace solid-phase microextraction (HS-SPME) methods were subsequently analysed by GC and GC/MS and compared. Thirty-seven and 20 components of the flower of E. ilicifolius were characterized, representing 99.7% and 100.0% of the total compos...

Echinops L., es un género de Asteraceae y contiene ca. 76 especies en Irán. La investigación actual se basa seis nueve poblaciones, incluidas E. cephalotus, chorassanicus, elebursessis, leiopolycerus, ritroides robustus. frecuencia distribución quiasmas, la asociación cromosómica segregación han sido analizadas para caracteres meióticos. En las estudiadas observado irregularidades meióticas, cr...

From flora of North West of Iran, four contrasting species in term of frequency and coverage on heavy metal rich soils were selected to study physiological mechanisms for different tolerance of Zn and Cu toxicity in a hydroponic culture experiment. For study of Zn toxicity, Dactylis glomerata and Secale monatum and for Cu, Cichorium intybus and Astragalus echinops were selected. A clear differe...

Phytochemical investigation of the flowering aerial parts of Echinops galalensis (Asteraceae) led to the isolation of a new taraxasteryl triterpene, 3b-acetoxy-taraxast-12, 20(30)-diene-11a-21a-diol (1), together with nine known metabolites, a-amyrin (2), b-sitosterol (3), erythrodiol (4), lup-20(29)-ene1,3-diol (5), 1,5-dicaffeoylquinic acid (6), 3,5-dicaffeoylquinic acid (7), 3,4-dicaffeoylqu...
