An insect antifeedant limonoid from seed of khaya ivorensis [PDF]

Phytochemistry, 1992
Abstract A novel limonoid which is an insect antifeedant has been isolated from a methanolic extract of seeds of Khaya ivorensis . Its structure was determined on the basis of one and two-dimensional NMR. spectroscopy and chemical evidence.

Limonoid Extractives from Khaya ivorensis

Journal of the Chemical Society C, Organic, 1970
The timber of Khaya ivorensis contains khivorin, small amounts of swietenolide esters and other limonoids; the seed contains mainly methyl angolensate, and the root bark contains a complex mixture of limonoids. One of the new compounds from the timber, methyl ivorensate, has been found to contain a ring A lactone system, similar to that in nomilin, and

Mexicanolide limonoids from the seeds of Khaya ivorensis with antimicrobial activity

Journal of Asian Natural Products Research, 2022
The methanol extract of the seeds of Khaya ivorensis afforded two new mexicanolide limonoids, ivorensines A and B (1 and 2), together with one known compound, ruageanin D (3). The structures of the isolated compounds were established based on 1 D and 2 D (1H-1H COSY, HMQC, and HMBC) NMR spectroscopy, in addition to high resolution mass spectrometry ...

Antifungal activity of limonoids from Khaya ivorensis

Pest Management Science, 2004
AbstractChemical investigation of the diethyl ether extract of the stem bark of Khaya ivorensis A Chev (Meliaceae) afforded ten limonoids of angolensates, ring D‐opened limonoids and mexicanolides. The structures of the limonoids isolated were determined by comparison of their 1H and 13C NMR data with those reported in the literature.
