Extractives from Khaya senegalensis(Desr.) A. Juss

Journal of the Chemical Society C: Organic, 1968
The timber, bark, root bark, roots, leaves, and seeds of Khaya senegalensis have been extracted with light petroleum. The known compounds 7-deacetoxy-7-oxokhivorin, khayasin, khivorin, methyl angolensate, mexicanolide, and 7-deacetoxy-7-oxogedunin have been isolated, together with a number of new compounds.

Khayanolides, rearranged phragmalin limonoid antifeedants from Khaya senegalensis

Tetrahedron, 2001
Abstract Three new rearranged phragmalin-type limonoids, named khayanolides A, B and C, were isolated as insect antifeedant together with four known rings B,D-seco compounds, seneganolide, methyl angolensate and its 6-hydroxy and 6-acetoxy derivatives from the ether extract of the stem bark of Khaya senegalensis.

New Structurally Diverse Limonoids from the Seeds of Khaya senegalensis

Planta Medica, 2016
Twelve new limonoids (khasenegasins O-Z; 1-12) with three different kinds of skeletons, including eight mexicanolides, two gedunins, and two andirobins, together with four known limonoids (13-16) were isolated from the seeds of Khaya senegalensis. Their structures were determined by extensive spectroscopic analyses (HR-ESI-MS, 1D/2D NMR), and the ...

Plant gums of the genus Khaya. Part V. Further studies on Khaya senegalensis gum

Journal of the Chemical Society C: Organic, 1970
The fractionation of deacetylated Khaya senegalensis gum has been re-examined. The main component of the gum, polysaccharide A, has been converted into the carboxy-reduced derivative, and oligosaccharides formed on acetolysis of the modified polysaccharide have been shown to include 4-O-rhamnopyranosylgalactose (I), 4-O-galactopyranosylgalactose (II ...

In vitro propagation of the African mahogany Khaya senegalensis

New Forests, 2010
A protocol was developed for shoot proliferation and plantlet formation of Khaya senegalensis, an important medicinal and timber plantation species introduced to Australia and southern Asia from western and central Africa. We assessed effects of the plant growth regulators, benzyladenine, kinetin, naphthalene acetic acid and gibberellic acid, on shoot ...

EQUAÇÕES HIPSOMÉTRICAS PARA KHAYA SENEGALENSIS (DESR.) A. JUSS

ARACÊ
A altura é importante para entender o comportamento de uma espécie ao longo do tempo e avaliar a qualidade da área para produção de madeira, podendo ser medida ou estimada. Os modelos hipsométricos permitem estimar a altura a partir do diâmetro da árvore, reduzindo custos do inventário florestal. A presente pesquisa teve como objetivo ajustar um modelo

Machining characteristics of khaya senegalensis and anogeisus leiocarpus

Ghana Journal of Forestry, 2012
Khaya senegalensis (Kuntunkuri) and Anogeisus leiocarpus (Kane) have been found to be in abundance in the Savannah Zone of Ghana where other Ghanaian primary species are scarcely available. In contribution to the promotion of these species, the turning, shaping, boring and sanding properties were studied.

Khaya Senegalensis inhibitory activity against α-glucosidase

Caliphate Journal of Science and Technology
α-glucosidase is an enzyme responsible for the hydrolysis of oligosaccharides to simple absorbable sugars. The inhibition of the enzyme is implicated in the management of postprandial hyperglycaemia. The current study evaluates the α-glucosidase inhibitory potentials of Khaya senegalensis stem bark.
