Ivorenoids A–F: limonoids from Khaya ivorensis

Tetrahedron, 2014
Abstract 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

Phytoremediation potential of Khaya ivorensis and Cedrela fissilis in copper contaminated soil

Journal of Environmental Management, 2020
Mineral 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 phytoremediation programs.

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 ...

Plant gums of the genus Khaya. Part IV. Major component of Khaya ivorensis gum

Journal of the Chemical Society C: Organic, 1970
Fractionation of deacetylated Khaya ivorensis gum affords a major polysaccharide component in essentially homogeneous form. Partial acid hydrolysis of this gives a degraded galacturonan and the following oligosaccharides, 2-O-(α-D-galactopyranosyluronic acid)-L-rhamnose (I), 4-O-(4-O-methylglucopyranosyluronic acid)galactose (II), 4-O ...

Elementology, fastness and fungicidal performance of Khaya ivorensis stem bark extracts

Journal of the Indian Academy of Wood Science, 2019
Khaya ivorensis (KI) represents one of the mostly used medicinal/pesticidal plants in Nigeria. While investigations into its chemical compositions and biological activity have been severally reported, little is known about the elementology, fastness and fungicidal performance of KI parts on wood.

Mexicanolide limonoids from Khaya ivorensis with anti-hyaluronidase activities

Journal of Asian Natural Products Research
Phytochemical study on 80% methanol extract from the seeds of Khaya ivorensis resulted into the isolation of three undescribed mexicanolide limonoids, ivorensisines A-C (1-3). Structural elucidation of all the compounds were performed by spectral methods such as 1D and 2D (1H-1H COSY, HMQC, and HMBC) NMR spectroscopy, in addition to high resolution ...

Studies on the anti-inflammatory and toxic effects of the stem bark of Khaya ivorensis (Meliaceae) on rats

Phytomedicine, 2004
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 ...

Khaya ivorensis A. Chev -Early Response to Nutrient Deficiencies in Forest Plantation Nursery

The Planter, 2008
Macronutrients are essential elements for the growth and development of forest tree species. The lack of sufficient nutrients may adversely affect the growth and quality of the plants. The objective of this study was to observe and determine the initial macronutrient deficiency symptoms on the growth and vigour of Khaya ivorensis seedlings.
