Analysis of flavonoid diglycosides in leaves of Mentha piperita L by MALDI-MS/MS and LC-MS
Ousmane Ilboudo, Issa Tapsoba, Igor W Ouedraogo, Pascal Gerbaux Yvonne L. Bonzi-Coulibaly
Flavonoids represent a large group of natural compounds with an impressive variety of biological activities, such as antioxidant [1], anti-inflammatory [2], antiallergic [3], antiplasmodial [4], anti-cancer [5], antimicrobial [6], antifungal [7], and neuroprotective [8] properties. Many biological properties of Mentha piperitaex-tracts are att(...)

CYCLIC VOLTAMMETRY AND REDUCTION MECHANISTIC STUDIES OF STYRYLPYRYLIUM PERCHLORATES
Jean Claude W. Ouédraogo1, Issa Tapsoba1, Boubié Guel2, Faustin Sié Sib1 and Yvonne Libona Bonzi-Coulibaly1*
The reduction and oxidation potentials of methylated 4-styrylpyrylium and 6-styrylpyrylium perchlorates have been evaluated using cyclic voltammetry, in comparison to their non-methylated derivatives values. The reduction peak of all studied compounds remained chemically irreversible. The presence of the electron-donating methyl group on pyryl(...)

Targeting Structural Motifs of Flavonoid Diglycosides Using Collision-Induced Dissociation Experiments on Flavonoid/Pb2+ Complexes
Ousmane Ilboudo, Issa Tapsoba, Yvonne L. Bonzi-Coulibaly, Pascal Gerbaux
Differentiation of flavonoid congeners remains a challenging analytical problem and confirming the structures of the different isomers is difficult, even when they can be adequately separated from mixtures. In the present report, in order to overcome the limits of our recently proposed method that relies on the distinctive CID behaviors of [(f(...)

Adsorptive removal of α-endosulfan from water by hydrophobic zeolites. An isothermal study
Arsène H. Yonli, Isabelle Batonneau-Gener, Jean Koulidiati
This paper deals with the removal of α-endosulfan from water over HY and steamed HBEA zeolites. Experiments were performed to understand the adsorption mechanisms of α-endosulfan on zeolites and to determine the most efficient adsorbent for the purification of water contaminated by this pesticide. The experiments exhibit that α-endosulfan was(...)

Collision-induced dissociation of flavonoid 7-O-diglycoside cations: elucidation of important structural motifs by selection of the cationizing reaction
Ousmane Ilboudo, Issa Tapsoba, Yvonne L Bonzi-Coulibaly, Pascal Gerbaux
Flavonoids are ubiquitous molecules in nature and are found in almost all plants, including fruits and vegetables. Although flavonoids are structurally similar, subtle differences in their structures lead to important changes in their biological activities. Over years, mass spectrometry has become an ideal tool for the characterization of thos(...)

Calcium behaves as a chemical messenger in a wide variety of cells, and local variations in its
concentration play a key role in many biological processes. 1,2 The understanding of how calcium
affects cellular functions necessitates the precise modulation of calcium concentration with high
spatial and temporal resolution. Tremendou(...)

Antioxidant potential of 4-acyl isochroman-1, 3-diones
Djandé Abdoulaye, Kiendrébéogo Martin, Compaoré Moussa, Kaboré Léopold, Nacoulma G. Odile, Aycard Jean-Pierre and Saba Adama
A new family of compounds (4-acyl isochroman-1,3-diones), demonstrating antioxidant properties, have been
synthesized and described. Their antioxidant properties are studied herein. These antioxidant characters increased with
the electronic withdrawing character of the acyl substituent. So, 4-p-Cyanobenzoyl isochroman-1,3-dione and 4-pNitrob(...)

Des études sur la qualité des eaux souterraines et de surfaces au Burkina Faso ont révélé un niveau élevé de contamination de ces ressources par les métaux lourds, notamment dans le milieu urbain et aux alentours des mines. La présence de ces métaux est principalement due aux activités anthropiques liées à l’industrie, l’agriculture ou encore(...)

Solvent induced aggregation of protoporphyrin and octacarboxylphthalocyanine of zinc deposited on gold surface.
Virginie Gadenne, Mabinty Bayo-Bangoura, Louis Porte, Lionel Patrone.
In this paper, we studied the influence of solvent on the morphology of zinc protoporphyrin and zinc
octacarboxylphthalocyanine films transferred onto gold surface by dipping. In these films, carboxylic acid
groups borne in periphery of macrocycles allow anchoring to gold via ionic interaction. First, we followed
by UV–Visible absorption sp(...)

Antipassivating electrochemical process of glassy carbon electrode (GCE) dedicated to the oxidation of nitrophenol compounds
M. Pontié, G. Thouand, F. De Nardi, I. Tapsoba, S. Lherbette
We report for the first time a novel electrochemical treatment applied to a glassy carbon electrode (GCE) during p‐nitrophenol (PNP) oxidation and dedicated to the limitation of electrode passivation by nitrophenol compounds oxidation. We propose an electrochemical process of direct phenol oxidation by starting the electrolysis at a very low p(...)
