Plant gums of the genus Khaya. Part V. Further studies on Khaya senegalensis gum
Journal of the Chemical Society C: Organic, 1970The 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 ...

Tetranortriterpenoids from Khaya senegalensis
Phytochemistry, 1998Preparative HPLC of an ethanol extract of seeds of Khaya senegalensis yielded three new tetranortriterpenoids of the mexicanolide type. These compounds were identified as 2-hydroxymexicanolide, 6-deoxydestigloylswietenine and 2,3-dihydroxy-3-deoxymexicanolide.

Phytotaxa, 2023
Khaya senegalensis is a tropical plant native to Africa and grown as an ornamental plant in Southern China. During our sample collection in Guangdong Province, China, a saprobic Dothideomycetes was collected from a dead stem of K. senegalensis. The collection was identified as a neomassaria-like species based on the morphology.

Antifungal limonoids from the fruits of Khaya senegalensis
Fitoterapia, 2004Investigation of the fruits of Khaya senegalensis resulted in the isolation of three new mexicanolide limonoids containing a rare conjugated diene lactone system named seneganolide A (1), 2-hydroxyseneganolide A (2) and 2-acetoxyseneganolide A (3). Two known limonoids, 3-deacetyl-7-deacetoxy-7-oxokhivorin (4) and methyl 6-hydroxyangolensate (5), were ...

Limonoids from the stem bark of Khaya grandifoliola
Phytochemistry, 2008Three limonoids, deacetylkhayanolide E (1), 6S-hydroxykhayalactone (2), and grandifolide A (3), along with three known ones, were isolated from stem bark of the Nigerian medicinal plant Khaya grandifoliola. Their structures were characterized on the basis of the application of spectroscopic methods.

Limonoids and Triterpenoids from Khaya senegalensis
Journal of Natural Products, 2010Seven new limonoids (1-7), named khayalenoids C-I, three new triterpenoids (8-10), named senegalenes A-C, and eight known limonoids have been isolated from stems of Khaya senegalensis. The structures of these compounds were elucidated on the basis of spectroscopic analyses.

Limonoids from leaves of Khaya senegalensis
Phytochemistry, 1997Abstract The leaves of Khaya senegalensis yielded two new limonoids. These compounds were identified on the basis of spectroscopic analysis as methyl 1α-acetoxy-3β,6,8α-trihydroxy-2α-methoxy-2β,14β-epoxy-[4.2.1 10,30 .1 1,4 ]-tricyclomeliac-7-oate and methyl 1α-acetoxy-6,8α,14β,30β-tetrahydroxy-3-oxo [3.3.1 10,2 .1 1,4 ]-tricyclomeliac-7-oate ...

Mechanische Eigenschaften von Khaya-Mahagoni
Holz als Roh- und Werkstoff, 1992Bei Biege und Zugbelastung sowie bei Druck belastung parallel und quer zur Faserrichtung wurden die Elastizitatsmoduln und die Festigkeiten von Khaya sp. bestimmt. Der Druck- und der Zug-Elastizitatsmodul: dies gilt auch fur andere Holzarten, wie herangezogene Literaturwerte zeigen. Nach einem Vorschlag von Bechtel, Norris (1952) wird die Zugfestigkeit
