Phenolic Compounds and Related Enzymes as Determinants of Sorghum for Food Use

DICKO Mamoudou. H., GRUPPEN, H., TRAORE, A. S.; van BERKEL, W. J. H. and VORAGEN, A. G. J.

Phenolic compounds and related enzymes such as phenol biosynthesizing enzymes (phenylalanine ammonia lyase) and phenol catabolizing enzymes (polyphenol oxidase and peroxidase) are determinants for sorghum utilization as human food because they influence product properties during and after sorghum processing. Phenolic compounds are quality-grad(...)

Régénération sexuée de Boswellia dalzielii Hutch., un arbre médicinal de grande valeur au Burkina Faso

Amadé Ouedraogo, Adjima Thiombiano, Karen Hahn-Hadjali, Sita Guinko

Résumé Boswellia dalzielii Hutch. est une plante principalement utilisée en pharmacopée traditionnelle. Elle compte parmi les espèces les plus menacées à l'est du Burkina Faso. L'espèce subit un écorçage intensif, qui la met en péril, et sa régénération est faible. Une collecte de fruits a été réalisée dans plusieurs peuplements pour étudier l(...)

Adaptative response of two varieties of cowpeas to water stress

HAMIDOU, F., Mamoudou H. DICKO ZOMBRE, G., TRAORE, A. S., and GUINKO, S

This study examined the adaptive response of the cowpea (Vigna unguiculata (L.) Walp.) to water stress at the beginning of pod formation. The regulation of carbohydrate levels, sucrose and starch in particular, was monitored in two varieties: local Gorom and KN1. In addition, the specific leaf mass and components of yield were studied. When th(...)

Impact of Phenolic Compounds and Related Enzymes in Sorghum Varieties for Resistance and Susceptibility to Biotic and Abiotic Stresses

DICKO Mamoudou. H., GRUPPEN, H., Barro, C.; TRAORE, A. S.; van BERKEL, W. J. H. and VORAGEN, A. G. J

Contents of phenolic compounds and related enzymes before and after sorghum grain germination were compared between varieties either resistant or susceptible to biotic (sooty stripe, sorghum midge, leaf anthracnose, striga, and grain molds) and abiotic lodging, drought resistance, and photoperiod sensitivity) stresses. Independent of grain ger(...)

Composition and antimicrobial activities of the leaf and flower essential oils of Lippia chevalieri and Ocimum canum from Burkina Faso

Bassole IHN , Nebie R , Savadogo A , Ouattara CT , Barro N , Traore SA

The essential oils of the air dried leaves and flowers of Lippia chevalieri Moldenke and Ocimum canum Sims from Burkina Faso were analysed by GC-MS. Essential oil of the leaves of L. chevalieri is composed mainly of thymol (27.4%), p-cymene (21.1%), and 2-phenyl-ethyl-propionate (12.6%), while the oils from flower is compo(...)

Indigenous West African plants as novel sources of polysaccharide degrading enzymes: application in the reduction of the viscosity of cereal porridges

144. DICKO Mamoudou. H., Searle-van LEEUWEN, M. J. F., BELDMAN, G., OUEDRAOGO, O. G., HILHORST, R. and TRAORE, A. S

Ethnobotanical and biochemical surveys revealed that some local plants from West Africa are novel sources of polysaccharide degrading enzymes such as amylases and glucanases. The study shows that these enzymes could be used for various biotechnological applications. In a crude extract of Curculigo pilosa, ß-amylase was the main starch hydrolyz(...)

Acute toxicity and antioxydant property of Striga hermonthica (Del.) Benth (Scrophulariaceae)

Martin Kiendrebeogo, Marie-Geneviève Dijoux-Franca, Charles Euloge Lamien, Aline Meda, Denis Wouessidjewe

Plants containing flavonoids have been reported to possess strong antioxidant properties. The aqueous acetone extract of Striga hermonthica was further separated into aqueous and ethyl acetate fractions and assayed for their in vitro antioxidant properties using 2,2-diphenyl-1-picrylhydrazyl (DPPH). The crude extract exhibits a weak antioxidan(...)

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(...)

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(...)
