Mexicanolide limonoids from the seeds of Khaya ivorensis with antimicrobial activity
Journal of Asian Natural Products Research, 2022The 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

Phytoremediation potential of Khaya ivorensis and Cedrela fissilis in copper contaminated soil.
Journal of Environmental Management, 2020Mineral exploration of copper (Cu) in the Amazon has significantly impacted the environment, leading to contamination of large areas that require remediation. Tropical tree species that can immobilize metals and restore plant cover should be selected for

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.

Methyl angolensate changes in Khaya ivorensis after fungal infection
Phytochemistry, 2009 Khaya ivorensis with and without symptoms of stem and branch cankers, caused by Botryosphaeria rhodina were examined in order to determine whether the secondary metabolites in this plant were associated with a chemical defense response. This study provides evidence that the limonoid methyl angolensate (MA) is present at higher concentrations in K ...

Limonoid Extractives from Khaya ivorensis
Journal of the Chemical Society C, Organic, 1970The 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

Ivorenoids A–F: limonoids from Khaya ivorensis
Tetrahedron, 2014Abstract Six new limonoids, ivorenoids A–F ( 1 – 6 ), along with ten known analogues, were isolated from an ethanolic extract of the stems of Khaya ivorensis . Their structures were elucidated on the basis of spectroscopic analyses. Compounds 1 and 2 possessed a rare rearranged skeleton of khayanolides and a unique γ-lactone (C-16/C-8) replacing

Khaya ivorensis A. Chev. (Meliaceae) is a common feature in anti-malarial recipe prescribed by African traditional medical practitioners. Investigations have proved that Khaya species possesses some level of anti-plasmodial activity. Anti-inflammatory and toxicity studies were carried out on this plant using the Ugo Basile model 7140 and routine ...

Response of shooting hormones on the stem cuttings of Khaya ivorensis A. Chev.
Journal of Research in Forestry, Wildlife and Environment, 2019 The study investigated the effect of different hormones on the stem cuttings of Khaya ivorensis. The experiment was made up of five treatments which are (treatment one) Benzyl Amino Purine at 0.01gm/m level of concentration, (treatment two) kinetin at 0.01gm/m level of concentration, (treatment three) combination of both kinetin and benzyl amino purine,
