This work is based on a phytochemical and biological study of two species of the genus Verbascum namely the endemic species to Algeria Verbascum atlanticum Batt. and the species Verbascum creticum Cav. which has not been the subject of any phytochemical study before. This investigation allowed the isolation and the purification of 20 products by using of several chromatographic techniques (CC, TLC, HPLC), the structures were identified by the different spectral methods (NMR1D and 2D), by the spectrometry of high resolution mass (HR-ESI-MS, LC-UV-MS,) and by comparing literature data. The biological activity is tested by the antioxidant activity on seven tests in vitro namely the DPPH inhibition, ABTS, CUPRAC, reducing power, metal chelating effect, anti-bleaching effect of β-carotene, superoxide alkaline. The effect of the acetylcholinesterase inhibition and butrylcholinesterase, the effect of protection against UVB rays and the antibacterial sensitivity test on the different extracts of the plants studied showed that these species have biological efficacy.

Munby Screening Flavonoïdes Flavonoids.Index. décimale : 540 Chimie et sciences connexes Résumé : This work is a part of our research program on the Algerian plants of the family Fabaceae.
Flavonoids are natural substances that play a protective role, due to their biological activities.
Therefore, our work is oriented to the extraction, the separation, the purification and the
structure determination of the flavonoid compounds of two species of the kind Genista :
G. aspalathoides Lamk. ssp. erinaceoides (Lois) And G. quadriflora Munby. The
phytochemical screening performed on these two species allowed to the identification of
several chemical groups in particular flavonoids and isoflavonoids. The fulfillment of this
work required the use all liquid-phase chromatography battery and the use of the most
successful modern methods of phsiycal and chemical analysis, in particular, the mono and
bidimensional spectroscopy of nuclear magnetic resonance (RMN 1H, RMN 13C, COSY,
HSQC, HMBC), the spectroscopy of ultraviolet absorption and the high resolution mass
spectroscopy. All these methods allowed us to establish the isolated structures of the ethyl
acetate phase and the chloroform phase of the hydro alcoholic extract of the two studied
species. Finally, the results of biological tests performed on both species G. quadriflora
Munby and G. aspalathoides Lamk. ssp. erinaceoides, in particular the test on the antioxidant
activity (DPPH test) were satisfactory. The originality of this work is crowned by several
publications in international reviews.Diplôme : Doctorat en sciences En ligne : ../theses/chimie/BOU6771.pdf Format de la ressource électronique : Permalink : index.php?lvl=notice_display&id=9820 Recherche et détermination des métabolites secondaires de plantes issues de la famille des fabacées [texte imprimé] / Rabia Boukaabache, Auteur ; Ouahiba Boumaza, Directeur de thèse . - Constantine : Université Mentouri Constantine, 2015 . - 221 f. ; 30 cm.
