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(...)

Endogenous phenolics and starch modifying enzymes as determinants of sorghum for food use in Burkina Faso
Mamoudou Hama DICKO
The objective of this thesis is to screen for biochemical determinants in sorghum varieties cultivated in Burkina Faso to identify the best sorghum varieties to be used as source of bioactive components or for specific local foods, e.g. "tô", thin porridges for infants, granulated foods "couscous", and local beers "dolo". The results revealed(...)

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(...)

Utilisations, état des peuplements et régénération de cinq espèces ligneuses utilitaires dans l’est du Burkina Faso
Amadé Ouédraogo, Adjima Thiombiano, Sita Guinko
La raréfaction des espèces à importance économique et les besoins croissants en produits végétaux constituent de nos jours des facteurs d'aggravation de la pression sur les espèces utilitaires. L'exploitation abusive est la cause majeure de la destruction de nombreuses espèces végétales (Ozenda 1982). Dans les conditions climatiques précaires(...)

IMPACT DES TRAITEMENTS INSECTICIDES SUR LES ENNEMIS NATURELS DE BEMISIA TABACI (HOMOPTERA : ALEYRODIDAE) EN CULTURE COTONNIERE AU BURKINA FASO
O. GNANKINÉ 1,2, D. TRAORÉ 1, A. SANON∗ 2, P. A. OUEDRAOGO 2
La “mouche blanche ” du cotonnier, Bemisia tabaci (Gennadius),
longtemps considérée comme un nuisible secondaire, est devenue
depuis quelques années un ravageur d’importance économique du
cotonnier au Burkina Faso. Ce changement de statut pourrait résulter
d’une élimination massive des ennemis naturels de B. tabaci par les
nombreux traite(...)

The chemical composition of the essential oils of Lippia chevalieri and Lippia multiflora obtained from the air-dried leaves by hydrodistillation were analysed using GC and GC–MS. L. chevalieri and L. multiflora belonged to thymol/p-cymene/2-phenyl ethylpropionate and thymol/p-cymene/thymyl acetate chemotypes, respectively. The essential oils we(...)

Antimalarial activity of Sida acuta Burm. f. (Malvaceae) and Pterocarpus erinaceus Poir. (Fabaceae)
KAROU, D., Mamoudou H. DICKO, Sanon, S., Jacques, SIMPORE, Traoré, A. S
Among strategies to combat malaria, the search for new antimalarial drugs appears to be a priority. Sheering for new antimalarial activities, four plants of the traditional medicine of Burkina Faso: Combretum micranthum, Khaya senegalensis, Pterocarpus erinaceus and Sida acuta, were tested in vitro on fresh clinical isolates of Plasmodium falc(...)

RIA systems were developed and used to measure pregnancy-associated Glycoprotein (PAG) concentrations during gestation and the postpartum period in Azawak Zebu cows. Twelve females were palpated per rectum and diagnosed as pregnant. Blood samples were taken at 5±10-day intervals from approximately Week 8 of gestation until Week 10 postpartum ((...)

Bosea minatitlanensis sp. nov., a strictly aerobic bacterium isolated from an anaerobic digester
Aboubakar S. Ouattara, Essokazi A. Assih, Sebastien Thierry, Jean-Luc Cayol, Marc Labat, Oscar Monroy and Herve´ Macarie
A strictly aerobic, mesophilic bacterium, strain AMX 51T, was isolated from anaerobic digester sludge. Cells were Gram-negative, motile, non-sporulating, straight to curved rods with one polar flagellum. The isolate had phenotypic traits of the genus Bosea, including cellular fatty acid and substrate utilization profiles. Physiological charact(...)

The effect of age on male Glossina fuscipes fuscipes, Newstead, and Glossina palpalis palpalis, Austin (Diptera: Glossinidae) competiveness were investigated with a view to estimate optimal age for sterile male release. Sterile insect technique involves the mass production, sterilization and sequential release of males of the target species to(...)

Analysis of fifty sorghum [Sorghum bicolor (L.) Moench] varieties used in Burkina
Faso showed that they have different contents of phenolic compounds, peroxidase (POX),
and polyphenol oxidase (PPO). Most of the varieties (82%) had a tannin content less than
0.25% (w/w). POX specific activity was higher than the monophenolase and o-diphenola(...)

Zymography of Monophenolase and o-Diphenolase Activities of Polyphenol Oxidase
DICKO Mamoudou. H., HILHORST, R., GRUPPEN, H., LAANE, C., van BERKEL, W. J. H. and VORAGEN, A. G. J
A new procedure for the zymography of monophenolase and o-diphenolase activities of polyphenol oxidase (PPO), and peroxidase (POX) is proposed using a highly sensitive, chromogenic nucleophile 3-methyl-2-benzothiazolinone hydrazone (MBTH), which traps quinones. The procedure allowed the distinction between PPO isoenzymes from sorghum and mushr(...)
