Antiplasmodial Flavonoids from Erythrina sacleuxii
(Planta Med, 2006)The acetone extracts of the root bark and stem of Erythrina sacleuxii showed antiplasmodial activities against the chloroquine-sensitive (D6) and chloroquine-resistant (W2) strains of Plasmodium falciparum. Chromatographic ... -
Effect of fermentation on protein digestibility of soybean and sweet potato blends: aspergillus oryzae vs. Lactobacillus plantarum
(2009)The improvement of nutritional quality of foods through fermentation has been practiced for long.Fermentation imparts desirable characteristics to products and makes them more utilizable nutrient sources than the unfermented ... -
A New Sterol Diglycoside from Conyza floribunda
(The South African Journal of Chemistry, 2009)Chemical investigation of CH2Cl2 and MeOH extracts of Conyza floribunda have led to the isolation of (24S)-ethylcholesta-5, 22E, 25-trien-3-O-glucosyl (1” 4’)-rhamnoside (1), (24S)-ethylcholesta-5,25-dien-3-O- -glucoside ... -
Triterpenes of Commiphora holtziana oleo-gum resin
(NRC Research Press, 2009-07)Chemical analysis of the acetone extract of Commiphoraholtziana gum resin has led to the isolation of triterpenes characterized as methyl 3-oxo-1α,19α,28-trihydroxyurs-12-en-24-oate (1), methyl 3β-acetyl-2α,11α,19α,28-te ... -
Effects of Fermentation on the Total Carotenoids, Fat, Free Fatty Acids and Minera ls in Soybean and Sweetp otato Flour Blends
(Egerton Journal Of Science And Technology, 2010)Soybeans and sweetpotatoes are high in micronutrients and convertible carotenoids, respectively. Utilization of micronutrients is hampered by anti-nutritional factors intrinsic to nutrient sources. Carotenoids must first ... -
A new species of Tarabulida (Solifugae: Daesiidae) from Kenya, with the first complete description of a male of the genus
(Bio One, 2010)We describe a new species of Tarabulida Roewer 1933 from Kenya. This genus was previously known from only two species (Tarabulida ephippiata Roewer 1933 and Tarabulida fumigata Roewer 1933) from Libya, which were described ... -
Survey of sweet potato viruses in Western Kenya and detection of cucumber mosaic virus
(Journal of Plant Pathology, 2010)Sweet potato is an important food crop worldwide, but several pests and diseases limit its production. In eastern Africa, virus-induced diseases rank second to weevils in causing yield reduction. Symptomatic sweet potato ... -
Development of a multiplex PCR technique for simultaneous detection of sweet potato feathery mottle virus and sweet potato chlorotic stunt virus
(Edizioni ETS Pisa, 2010)Virus diseases, especially those caused by mixed infections, are among the economically most devastating diseases of sweet potato. Sweet potato virus disease (SPVD), which is caused by mixed infection of Sweet potato ... -
Nutritional quality and physicochemical properties of Mucuna bean (Mucuna pruriens L.) protein isolates
(2010)The potential for mucuna bean protein isolate (MBPI) application as functional ingredient in foods is unknown. In this study nutritional quality and physicochemical properties of MBPI were investigated. Bean samples were ... -
Bioactive Constituents of Conyza floribunda
(Medwell Journals, 2010)The study describes the antibacterial and antifungal effects of both CH2Cl2 and MeOH crude extracts, collected fractions and pure isolates of Conzya floribunda. The antimicrobial activity tests were carried out using agar ... -
Effects of processing technique on the nutritional composition and anti-nutrient content of mucuna bean (Mucuna pruriens L.)
(Academic Journals, 2010-04)Mucuna bean (Mucuna pruriens) is an indigenous legume promoted in Kenya as a green manure cover crop. It contains high protein but it is under - utilized due to the presence of 3, ... -
EFFECTS OF PROCESSING METHODS ON THE PROTEIN QUALITY OF MUCUNA BEAN (MUCUNA PRURIENS L.)
(2010-04)Mucuna bean (Mucuna pruriens L.) is grown in many parts of Kenya as a green manure/cover crop. The bean contains a high content of crude protein. However, it remains a minor food crop due to the presence of anti-nutritional ... -
