of the septentrional Sahara from the Cistaceae family: Helianthemum ruficomum and
Helianthemum confertum. To our best knowledge, no studies are reported so far for these
species. The purpose of this work was to investigate the chemical composition and the
radical scavenging capacity of these species and their isolated components.
The ethyl acetate and «-butanol soluble parts of the aqueous-ethanol extracts of the
aerial parts of these species were evaluated for their free radical scavenging capacity by
ABTS'+ assay. The obtained data which showed important antioxidant powers were
confirmed by TEAC and ORAC assays. On-line HPLC- ABTS'+ assays were then applied to
screen the extracts. The results which revealed remarcable wealth in antioxidants allowed
guiding the fractionation of the extracts by column chromatography on silica gel 60. The
obtained fractions were purified by chromatography on preparative plates of silica
gel 60 and/or by semi-preparative reverse phase HPLC leading to the isolation and the
identification of 14 compounds from H. ruficomum and 6 compounds from H confertum. The
compounds were identified by spectral analyses, mainly ESI-HRMS (+), UV, ID NMR (*H,
13C, DEPT) and 2D NMR (DOSY, COSY, NOESY, HSQC and HMBC) and comparison of
their spectroscopic data with those reported in the literature.
The antioxidant power of the isolated compounds was also evaluated by on-line
HPLC-ABTS'+, TEAC and ORAC. The results clearly indicate high antioxidant potential
of the extracts and tested compounds isolated from these two species.
This work was the object of a published paper and two other in progress.Diplôme : Doctorat En ligne : ../theses/chimie/CHE7110.pdf Format de la ressource électronique : Permalink : https://bu.umc.edu.dz/md/index.php?lvl=notice_display&id=10491 Valorisation genre helianthemum- de plantes sahariennes activité antioxydante endémiques du genre Helianthemum -activité antioxydante [texte imprimé] / Yasmine Chemam, Auteur ; Fadila Benayache, Directeur de thèse ; Eric Marchioni, Directeur de thèse . - [S.l.] : جامعة الإخوة منتوري قسنطينة, 2017 . - 270 f. ; 30 cm.

The present work concerns of photochemistry study of flavonoids isolated from Thymus serpyllum, Thymus algeriensis, and Salvia officinalis, and an evaluation of their antioxidant and antibacterial activities.
The rate of total phenols ranged from 16, 64 to 25,47 mg GAE / g extract, whereas the rate of flavonoids is 1,7 to 2,4 mg QE/ g extract. The antioxidant activity is seems very important, whose the results vary from 88% to 92% for T. algeriensis, 81% to 92% for T .serpyllum, and 87% to 92% for S. officinalis.
The results of antibacterial activity showed that luteolin and its derivatives have significant inhibitory effect against the bacterial species tested.Diplôme : Magistère En ligne : ../theses/biologie/MAD5582.pdf Permalink : https://bu.umc.edu.dz/md/index.php?lvl=notice_display&id=1818 Caractérisation et comparaison du contenu polyphénolique de deux plantes médicinales (Thym et Sauge) et la mise en évidence de leurs activités biologiques [texte imprimé] / Aicha Madi, Auteur ; Université Mentouri, Editeur scientifique ; R Merghem, Directeur de thèse . - 2009 . - 106 f.

Q. et S. and Serratula cichoracea. The works carried out on Centaurea solstitialis ssp. schouwii (CD.) Q. et S.began with the maceration in 70% ethanol of the aerial parts collected in the flowering stage from the area of El Kala. After filtration,concentration and dilution in distilled water,theremaining solution was successively extracted with petroleum ether, CHCl3, EtOAcand n-BuOH to give the corresponding extracts.The antioxidant abilities of CHCl3, EtOAc and n-BuOH extracts were assessed using DPPH radical scavenging, and cupric ion reducing antioxidant capacity (CUPRAC).Butylhydroxyanisole (BHA), Butylhydroxytoluene (BHT) and α –Tocopherol were used as controls. The total phenolic and total flavonoid contents of the extracts were also determined. Concerning the antioxidant activity, the EtOAc extract was the most active followed by the n-BuOH extract in the two methods.
However, none of the extracts exhibited higher activity than those of the antioxidant standards.
The n-BuOH extract had the highest phenolic and flavonoid contents followed by EtOAc extract.
These data allowed guiding the fractionation of EtOAc and n-BuOH extracts which was carried out by chromatography on silica gel60column. The obtained fractions, purified bychromatography on preparative normal silica gel plates led to the isolation of twosesquiterpene lactones with guaianolide skeleton-type one of which was new, we describe it for the first time in the literature. We also isolated 5 flavonoid glycosides.The structures of all the isolated compounds were established by the analyses of: the high resolution mass spectra recorded in ESI positive mode [HRESI-MS(+)], the results of UV-Vis spectral series , the 1D NMR (1H, 13C and DEPT) and 2D NMR (COSY, NOESY, HSQC and HMBC) spectra, the results of the acidic hydrolysis of the glycosylated compoundsand finallywith comparison of their spectroscopic data with those reported in the literature. Concerning the species Serratula cichoracea, the carried out work represents continuity
of a study that we previously realized on the ethyl acetate extract obtained by a protocol
similarto that indicated higher forCentaurea solstitialis ssp. schouwii (CD.) Q. et S., after
fractionation of this extract on silica gel column, the study of one of the obtained fractionsallowed the isolation and the structural determination of two ecdysteroid iastereoisomers.
One of these two compounds was new, we reported it for the first time in the literature.
These works were the object of two international publications.

Index. décimale : 540 Chimie et sciences connexes Résumé : This work presents the electrochemical behavior of three types of molecules: synthetic, biosynthetic and natural.
Heterocyclic compounds from nitrophenyl acetic acid were synthetized and evaluated for their electroactivities and cytotoxic properties.
The electrochemical oxidation of native and denatured BEVA was investigated in solution over a wide pH range and using BEVA-thin film voltammetry on a glassy carbon electrode.
For native BEVA, only one pH-dependent oxidation peak, corresponding to tyrosine and tryptophan amino acid residues oxidation, was observed. On the other hand, the electrochemical oxidation of denatured BEVA thin film on GCE showed additional cysteine and histidine residues oxidation peaks.
Flavonoids present in the extracts of Mediterranean freeze-dried fruits: apricot, cherry, plum, pomegranate, date, prickly pear and nectarine were detected by high-performance liquidphase chromatography with inverse phase (RP-HPLC) coupled with photodiode array (PDA) and electrochemical detection (ED).
The total antioxidant activity of these extracts was investigated by differential pulse voltammetry (electrochemical index-EI and peak area-Parea) and chronoamperometry (peak intensity-Ia). A comparative study was carried out by free radical scavenger efficient concentration (EC50), using 2, 2-diphenyl-1-picrylhydrazyl (DPPH) assay.Diplôme : Doctorat en sciences En ligne : ../theses/chimie/ISS7183.pdf Format de la ressource électronique : Permalink : https://bu.umc.edu.dz/md/index.php?lvl=notice_display&id=10737 Comportement électrochimiques des hétérocycles azotés et des biomolécules biologiquement actifs.

This study led to the isolation and identification of fifteen compounds of Cotula anthemoides and eight compounds of Pentzia monodiana including five phenolic acids, nine flavonoids from which one is new, three lignans, one sesquiterpene lactone, two glycosyl phenolics, a glycosyl acid, a diterpene and an nucleoside. The structural determination of the isolated compounds was established by the use of 1D and 2D NMR spectroscopic techniques (1H, 13C, COSY, HSQC, HMBC and ROESY), by mass spectrometry (ESI-MS and HRESI-MS) and by comparison with the literature data. The evaluation of the antioxidant activity by 4 methods (DPPH, ABTS, CUPRAC and chelating by ferrous ions) of the various extracts, showed a good activity of extracts from P. monodiana compared to those of C. anthemoides. Furthermore, extracts of C. anthemoides showed an interesting anticholinesterase activity. However, both of lignanes, flavonol and flavones substituted in C-3, exhibited better antityrosinase and antiradical activities than some flavones only.
