Khayanolides from African mahogany Khaya senegalensis (Meliaceae): A revision

Phytochemistry, 2009
Five khayanolides (1-O-acetylkhayanolide B 1, khayanolide B 2, khayanolide E 3, 1-O-deacetylkhayanolide E 4, 6-dehydroxylkhayanolide E 5) were isolated from the stem bark of African mahogany Khaya senegalensis (Meliaceae). Their structures and absolute configurations were determined through extensive spectroscopic analyses including MS, NMR, and single-

Three New Modified Limonoids from Khaya senegalensis

Journal of Natural Products, 2002
Three new rings B/D opened limonoids, two rearranged phragmalin limonoids named khayanolides D and E (1 and 2), and one limonoid glucoside named khayanoside (3) were isolated as insect antifeedants from the stem bark of Egyptian Khaya senegalensis. The structures of these compounds were established by spectroscopic methods, including 2D NMR and CD.

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 ...

Fatty acid composition of the seed oil of Khaya senegalensis

Bioresource Technology, 1999
Abstract The oil from Khaya senegalensis seeds, a dry-zone mahogany plant, was soxhlet extracted with petroleum ether (40–60°C) and characterized by gas chromatograph and infra-red spectroscopy. The fatty acid constituents of the oil were stearic acid (10.41%), palmitic acid (21.39%), oleic acid (64.62%) and unidentifiable acid (3.58%).

Effect of Khaya senegalensis on uterine contractility in rats

2007
In a bid to establish a scientific rationale for the folkloric use of Khaya senegalensis the aim of this study was to determine the effect of the methanolic root bark extract of the plant on the rat uterus. With respect to uterine effects, the rat is the most appropriate animal model which can be extrapolated to man.

Machining characteristics of khaya senegalensis and anogeisus leiocarpus

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.
