limonoids from Khaya senegalensis

Phytochemistry, 1998
A new limonoid was isolated from the bark of Khaya senegalensis and identified as 2,6-dihydroxyfissinolide. The assignments of some signals in the (13)C NMR spectrum of fissinolide have been reversed and the signals of the (1)H NMR spectrum of methyl 3beta-acetoxy-6-hydroxy-1-oxomeliac-14-enoate have been assigned.

Tetranortriterpenoids from Khaya senegalensis

Phytochemistry, 1998
Preparative 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.

Antifungal limonoids from the fruits of Khaya senegalensis

Fitoterapia, 2004
Investigation 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 and Triterpenoids from Khaya senegalensis

Journal of Natural Products, 2010
Seven 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.

Extractives from the seed of Khaya senegalensis

Journal of the Chemical Society C: Organic, 1967
An examination of the seed of Khaya senegalensis A. Juss has given the known compounds khivorin and 7-deacetoxy-7-oxokhivorin, together with 3-deacetylkhivorin and a compound which is probably 7-deacetoxy-3-deacetyl-7-oxokhivorin. Examination of the nuclear magnetic resonance spectrum of 3-deacetylkhivorin shows that it is a 1α-7α-diacetoxy-3α-hydroxy ...
