Abstract:

The study sought to assess the impact of unfermented and fermented Afzelia africana seed flour on alloxan-induced diabetic rats on their triglyceride and cholesterol levels. 50 rats were involved in this research, and they were placed in five groups, ten rats per group. One group was kept normal, and four groups were made diabetic by injecting a freshly prepared 5% aqueous solution of alloxan monohydrate, given in a single dose of 130 to 170 mg/kg body weight. The composition of the experimental diet was formulated on the basis of 10g dietary fiber obtained from the seeds. Lipid profile levels

Abstract:

Afzelia Africana (African mahogany), commonly known as African oak, is a tropical African tree. It is valued for its high-grade timber but has good potential to provide fodder for livestock and food. The objective of this work there is to conduct a preliminary assessment on the effects of organic manure on early growth performance of African mahogany (Afzelia africana Sm. ex Pers.)

Abstract:

Mohagany bean seed (Afzelia africana) locally known as “akparata” in Nigeria among the Igbos is a food thickening agent with some nutritional values. However, the availability of these nutrients is dependent on the processing method used on the seeds. Fermentation as one of the methods of processing was used in the processing of Afzelia africana seeds. The seeds were bought, sorted and roasted for 20 – 25 minutes on gas cooker at 145oC. Then dehulled, cracked into smaller pieces and divided into four portions. One portion was not soaked while three others were fermented for 24hrs, 48hrs and 72

This study, the first of its kind reports an in vitro shoot regeneration protocol in Afzelia africana. A. africana is a medicinal and multipurpose tree that is under permanent pressure from its continuous exploitation for medicine, food and timber products. Adding to its being under threat of extinction, the seeds are dormant and recalcitrant with a low rate of seed germination thus posing a challenge on its propagation through conventional planting. In vitro propagation method is appropriate for propagating A. africana since it can boycott the use of seeds. Leaf, nodal, cotyledonary node, sho

Abstract:

The use of renewable plant resources for the formulation of adhesives is increasingly promising, thanks to their availability at an affordable price and their high content of biomolecules such as polyphenols. The study of tannins therefore remains an active and ongoing area of research. This article presents a recent characterization of tannins extracted from the barks of four types of tropical trees (Entandophragma candolei, Entandophragma cylindricum, Afzelia africana and Dacryodes klaineana) and their application in the development of bioresins. Tannin extraction with hot water yielded betw

<strong>Abstract:</strong> This research explores the possibility of synthesizing surfactant using vegetable oil from <em>Afzelia africana</em> seeds through a two-step transesterification and sulfonation processes. The oil was extracted by Soxhlet using n-hexane as the solvent. Characterization in terms of physicochemical parameters gave the following results: 24.72 % oil yield, a value that compares favourably with other fatty acids used for similar applications, specific gravity of 0.93, refractive index of 1.48, saponification value of 204.03 (mgKOH/g), an acid value of 5.6 (mgKOH/g), and

Abstract:

This study investigated the ethnobotanical uses of Afzelia africana Sm. ex Pers., a threatened tree species in Nigeria to determine the impact of uses of this species on the risk of its extinction. Ethnobotanical surveys were conducted by means of semi-structured questionnaires with the local community called Ijebu Igbo in Ogun state of Nigeria and a total of 60 respondents were interviewed from this community. Herbalists, artisans, Islamic scholars, traders, and retirees were interviewed to document their knowledge of the uses of A. africana. This study revealed that there are different uses

The loading orientations were horizontal, vertical and edge-to-edge loading positions at four different moisture content levels of 10.6%, 12.8%, 15.2% and 18.4% wet basis (wb). Slight variations were observed in the means of the physical characteristics at varying moisture content in the range of 10.6% to 18.4%. Loading position was shown to have significant effect on all the mechanical properties studied. The rupture force increased with increase in moisture content in horizontal
