Anticancer activity of limonoid from Khaya senegalensis

Phytotherapy Research, 2007
AbstractTwo limonoids were isolated from the methanol extract of Khaya senegalensis (Meliaceae), and their structures were identified as 3α,7α‐dideacetylkhivorin (1) and 1‐O‐acetylkhayanolide B (2) on the basis of MS and NMR spectral data. Complete assignments of 1H and 13C chemical shifts for compounds 1 and 2 were achieved by means of 1D and 2D NMR ...

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.

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.

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%).
