Echinops wakhanicus Rech.f. (Compositae: Cardueae: Echinopsinae) is described and illustrated, its taxonomic position discussed. Field observations seed collection of the species are mentioned. The genus discussed, comments made on infrageneric classification, placement E. in sect. Oligolepis. terminology used describing flowering structure discussed; term synflorescence preferred. Tribal subtr...

Echinopines A (1) and B (2), novel sesquiterpenoids with an unprecedented rearranged skeleton named echinopane, were isolated from the roots of Echinops spinosus. The structures were elucidated by extensive spectroscopic analysis. The relative configuration of 1 was assigned by a combination of NOESY correlations and a simulation analysis. A plausible biosynthetic pathway for echinopane was dis...

extract of echinops persicus is traditionally used for a long time in iran for treatment of cough and constipation. this extract is produced by activity of bug (situphilus spp.) on the plant. we documented its anti-tussive effect in rats in our previous study.the aim of this study was to assess the anti-ulcer effect of echinops persicus in an animal model. in this study we evaluated anti-ulcer ...

A natural alkynol group-substituted thiophene, 2-(penta-1,3-diynyl)-5-(3,4-dihydroxybut-1-ynyl)-thiophene (PDDYT), was isolated from the roots of Echinops grijsii Hance. It possessed potent NAD(P)H: quinone oxidoreductase1 (NQO1) inducing activity and could activate Keap1-Nrf2 pathway effectively in murine hepatoma Hepa 1c1c7 cells. Further investigations indicated that the activation of Keap1-...

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...

The species of Asteraceae were used traditionally in treatment of inflammatory disorders. The present study aimed to assess the anti-inflammatory effect of methanolic extract of aerial parts of Rhanterium epapposum Oliv. (R.epapposum), Achillea fragrantissima (Forssk.) Sch.Bip (A. fragrantissima), Artemisia herba-alba Asso. (A.herba-alba), Echinops spinosus L. (E. spinosus) and Echinops hussoni...

A new thiophene, echinothiophenegenol (1), together with seven known thiophenes was isolated from the crude ethanol extract of roots of Echinops grijisii Hance. The structure of 1 was elucidated on the basis of spectroscopic data. Compounds 2 and 5, isolated from the plant for the first time, and compounds 1-7 were tested for their cytotoxicity against two human cancer cell lines, HL60 and K562...
