Performance of some quinoa (Chenopodium quinoa Willd.) genotypes in Kenya
(Taylor & Francis, 2010-01-01)
Quinoa (Chenopdium quinoa Willd.) has been cultivated for thousands of years in South America for its nutritious grain and leaves. Demand for the crop has risen in the recent past. In order to satisfy the demand, there is ...
Biofortified sorghum in Africa: using problem formulation to inform risk assessment
(Nat. Biotechnol., 2010)
Most of the genetically modified (GM) crops approved to date (eg, corn, cotton and soybean improved for insect resistance or herbicide tolerance) do not have compatible wild relatives near their intended area of cultivation, ...
Molecular diversity, geographic distribution and host range of monocot-infecting mastreviruses in Africa and surrounding islands
(Elsevier, 2017)
Maize streak virus (MSV), an important pathogen of maize in Africa, is the most extensively studied member of the Mastrevirus genus in the family Geminiviridae. Comparatively little is known about other monocot-infecting ...
Influence of Climatic Factors on the Δ13c Values of the C3, C4 And CAM Dicot Species (Vegetation) of the Centrospermeaealong Altitudinal Gradient in western Region of Kenya
(Research Gate, 2017)
Species of the Centrospermeae occurring at different altitudes were analyzed for δ13C values and assigned for graphical representation. The aridity of the study area was evident as defined using the Klimadiagramm. Climatic ...
Ecological implications of the ẟ13C values of plant species growing in natural environment, greenhouse and plant respired carbon dioxide (captured as carbonate).
(Research Gate, 2017)
ẟ13C values have been used to differentiate the C3 plant species from the C4 species. Light isotope (12C) is favoured against the heavier isotope (13C) during the carbon fractionation in plant species. The ẟ13C valuesof ...
Assessment of anti-proliferative activities of selected medicinal plant extracts used for Management of Diseases around Lake Victoria Basin
(ResearchGate, 2017)
The devastating effect of cancer is a worldwide concern. Unfortunately current chemotherapeutic and radio therapeutic modalities have been found to possess side effects coupled with the emergence of drug resistance. This ...
In Vitro Permeation of Mesembrine Alkaloids from Sceletium tortuosum across Porcine Buccal, Sublingual, and Intestinal Mucosa
(Planta Medica, 2012)
Sceletium tortuosum is an indigenous South African plant that has traditionally been used for its mood-enhancing properties. Recently, products containing S. tortuosum have become increasingly popular and are commonly ...
The chemotypic variation of Sceletium tortuosum alkaloids and commercial product formulations
(Elservier, 2012)
Commercial production and trade in Sceletium tortuosum and its products is on the rise due to an increase in consumer demand. Mesembrine-type alkaloids are the main active compounds responsible for the therapeutic properties ...
The chemotypic variation of Sceletium tortuosum alkaloids and commercial product formulations
(Pergamon, 2012)
Commercial production and trade in Sceletium tortuosum and its products is on the rise due to an increase in consumer demand. Mesembrine-type alkaloids are the main active compounds responsible for the therapeutic properties ...
An HPTLC-densitometry method for the quantification of pharmacologically active alkaloids in Sceletium tortuosum raw material and products
(Akadémiai Kiadó, 2012)
Mesembrine-type alkaloids are reported to be responsible for the psychoactive properties of Sceletium tortuosum. The aim of the study was to develop a simple, rapid, and precise high-performance thin-layer chromatography ...
