Sorghum Grain as Human Food in Africa: Relevance of Starch Content and Amylase Activities
132. DICKO Mamoudou. H., GRUPPEN, H., TRAORE, A. S.; van BERKEL, W. J. H. and VORAGEN, A. G. J
Sorghum is a staple food grain in many semi-arid and tropic areas of the world, notably in Sub-Saharan Africa because of its good adaptation to hard environments and its good yield of production. Among important biochemical components for sorghum processing are levels of starch (amylose and amylopectin) and starch depolymerizing enzymes. Curre(...)

Evaluation of the Effect of Germination on Phenolic Compounds and Antioxidant Activities in Sorghum Varieties
DICKO Mamoudou. H.,, GRUPPEN, H.; ZOUZOUHO O.C.; 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(...)

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(...)

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(...)

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(...)

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(...)
