Antioxidant and antibacterial activities of polyphenols from ethnomedicinal plants of Burkina Faso
KAROU, D., Mamoudou H. DICKO, SIMPORE, J., and Traoré, A. S
Polyphenols from four medicinal plants of Burkina Faso, Combretum micranthum, Khaya senegalensis, Pterocarpus erinaceus and Sida acuta, were screened for their antioxidant and antimicrobial activities against pathogenic bacteria. The medicinal plants displayed different polyphenols contents and antioxidant activities. The bark of P. erinaceus(...)

Evaluation of the Effect of Germination on Phenolic Compounds and Antioxidant Activities in Sorghum Varieties
DICKO, Mamoudou. H., GRUPPEN, H., TRAORE, A. S.; van BERKEL, W. J. H. and VORAGEN, A. G. J.
The screening of 50 sorghum varieties showed that, on average, germination did not affect the content in total phenolic compounds but decreased the content of proanthocyanidins, 3-deoxyanthocyanidins, and flavan-4-ols. Independent of germination, there are intervarietal differences in antioxidant activities among sorghum varieties. Phenolic co(...)

Voltammetric assay of Guaifenesin in pharmaceutical formulation
I. TAPSOBA
The electrochemical oxidation of Guaifenesin in a pharmaceutical formulation containing Guaifenesin has been carried out in Britton–Robinson buffer (BRB)(0.04 mol L− 1) on platinum electrode. Guaifenesin exhibits a well-defined irreversible oxidation peak at 0.924 V/ref. The influence of pH on the oxidation of Guaifenesin was studied in BRB (p(...)

Photoacoustic Approach to Direct Determination of the Total Phenolic Content in Red Sorghum Flours
DOKA, O.; BICANIC, D. D.; Mamoudou H. DICKO and Slingerland, M. A.
Photoacoustic (PA) spectroscopy in the ultraviolet and visible was demonstrated to be a suitable tool for direct determination of total phenolic content in red sorghum flours. The PA spectra obtained feature two characteristic peaks: the first centered at 285 nm is due to the aromatic amino acids, while the second one at 335 nm is associated w(...)

Using Habitat and Assets as Household Wealth Indexes: Methods and Policy Implications
Kobiané, Jean-François
La disponibilité des informations sur les caractéristiques de l'habitat et les biens possédés par les ménages dans les enquêtes démographiques, permet de plus en plus une étude des interrelations entre pauvreté et comportements socio-démographiques. Toutefois, les méthodologies de construction de ces proxys de niveau de vie sont diverses, sans(...)

Field evaluation of the efficacy and persistence of insect repellents DEET, IR3535, and KBR 3023 against Anopheles gambiae complex and other Afrotropical …
A. BADOLO
Synthetic insect repellents, IR3535 and KBR 3023 (also known as picaridin, or by the trade name Bayrepel®), were tested in Burkina Faso against mosquito vectors of disease to compare their relative efficacy and persistence profiles to those of the 'gold standard'DEET. Collection of> 49 000 mosquitoes (∼ 95% belonging to the Anopheles gambiae c(...)

Validation of gentamicin congeners using HPLC with electrochemical detection: Comparison with fluorimetric detection
Touridomon Issa Some, Rasmané Semdé, Moustapha Ouedraogo, Karim Amighi, Pierre I. Guissou, Pierre Duez and Jacques Dubois
OPA is often used as an off-line derivatisation agent for fluorimetric detection in gentamicin analysis. As, in general, electrochemical detection is more sensitive than fluorimetric detection, the analysis of gentamicin as its OPA derivatives by high-performance liquid chromatography and electrochemical detection is proposed. The derivatisati(...)

Résumé La carence en vitamine A (CVA) concerne plus de 250 millions d'enfants âgés de moins de cinq ans dans le monde. Cette carence et ses conséquences sanitaires sont surtout ressenties dans les pays en voie de développement. Trois approches complémentaires sont préconisées pour remédier aux conséquences de la carence en vitamine A: la suppl(...)

Electroxidation of ortho-substituted aromatic amines mechanistic investigation
I. TAPSOBA
The anodic oxidation of ortho-substituted aromatic amines has been investigated at a platinum electrode in aprotic solvent by cyclic voltammetry and controlled potential coulometry. In neutral medium, the radical cation stemming from the electron transfer undergoes deprotonation and a head-to-head coupling reaction leading to a dimer, which ev(...)

Electrochemical reduction of N-thioamidoimidates: application to the synthesis of thiazolo[5,4-d]thiazoles
I. TAPSOBA
The reduction of N-thioamidoimidates (1) has been examined in aprotic media at a mercury electrode. As shown by cyclic voltammetry at fast scan rates and controlled potential electrolysis, an overall irreversible one electron transfer is followed by a rapid second order chemical reaction leading to a dimer which involves to thiazolo [5, 4-d] t(...)

Perception paysanne de la dégradation de l'environnement sur le pourtour du lac du barrage de la Kompienga (Burkina Faso)
DIPAMA Jean-Marie
L'implantation du barrage hydroélectrique sur le cours de la Kompienga a engendré une dégradation de l'environnement sur l'ensemble du bassin versant. Par ailleurs, la présence d'un important plan d'eau et les potentialités agro-écologiques sont à l'origine d'important flux migratoires vers la zone de la Kompienga. La plupart des migrants, don(...)
