    Extraction and GC/MS Analysis of major Alkaloids found in the Family of Fabaceae
    (UNIVERSITE MOHAMED BOUDIAF - M’SILA, 2007-07-04) BENAICHE, Ghania
    Pendantl’étudeparGC/MSdel’extraitméthanoliquedupartiesaériennesduplante Cytisus purgans (Famille de Fabaceae) du Flore Algérienne , douze (12) alcaloïdes lupiniques (de type Lupin) ont été identifiées, dont onze (11) sont de type Sparteine (Sparteine-type) et un (1) est un alcaloïde piperidinique ( Ammodendrine ) . Ainsi que, 13α-Hydroxylupanine a été isolé en utilisant la TLC préparative. L'étude de l'activité antimicrobienne a montré que Cytisus purgans a une activité antibactérienne contre toutes les souches bactériennes testées.

    Extraction, separation and biological activities of some secondary metabolites from the plant Cytisus purgans
    (Université de m'sila, 2016-06-26) BENAICHE, Ghania
    In the present study the plant Cytisus purgans was investigated for its contents of secondary metabolites. Cytisus is a genus of the Leguminosae family, with six species endemic to Algeria. Cytisus balansae Boiss. (Cytisus purgans) is a rare species of Algeria (Aures, Mahdids, and Lella Khadidja). Phytochemical study revealed the presence of two known quinolizidine alkaloids which are : sparteine and lupanine which were isolated from methanolic extract of crude mixture of alkaloids using open column chromatography and identified by their spectroscopic data (IR, MS, 1H and 13C NMR) and comparing with literature. In the other side, two known flavonoids were isolated from crude mixture of polyphenols which are: quercetin and sarotanoside, using open column chromatography and identified by their spectroscopic data (UV, IR, MS, 1H and 13C NMR) and comparing with literature. Biological study mentioned that Cytisus purgans not show a significant antitumor activity against human breast cancer and human lung cancer but it shows a power antioxidant activity and a moderate antimicrobial activity.
