Compounds
Khaya senegalensis is a plant species characterized by a diverse profile of bioactive secondary metabolites. Chemical analyses of its stem bark and roots have identified the presence of chromones, which are believed to contribute to its antioxidant and enzyme-inhibitory properties. The species also produces specific limonoids, including the mexicanolide-type compounds khayanone and 2-hydroxyseneganolide. Furthermore, research has isolated the limonoid glucoside known as khayanoside from the plant's tissues. Together, these various chemical constituents highlight the complex phytochemical makeup of Khaya senegalensis.
Conditions
Khaya senegalensis exhibits significant antileishmanial activity against Leishmania donovani, demonstrating potent inhibitory effects in various screening studies. The plant also serves as an effective treatment for Plasmodium falciparum, with its extracts showing promise in combating both sensitive and multidrug-resistant strains of malaria. In the management of infectious diarrhea, its aqueous and hydroethanolic extracts demonstrate the ability to destabilize the outer membranes of responsible bacterial strains. Furthermore, Khaya senegalensis has been shown to be effective in treating animal African trypanosomosis, particularly when used in combination therapies. Finally, the plant's extract has been found to potently inhibit Agrobacterium tumefaciens-induced genetic transformation in carrot disk assays.
Preparations
Khaya senegalensis is prepared as aqueous and hydroethanolic extracts for studies evaluating antibacterial activity and toxicological safety. The plant is also prepared as barks, which are used in traditional medicine to treat animal African trypanosomosis and are traded heavily in herbal markets. Furthermore, Khaya senegalensis is prepared as stem bark for the isolation of various limonoids, such as khaysenelide and khayanolide. As an extract, the plant has demonstrated antimetastatic properties against HepG2 cell lines and strong anti-MTB activity. These diverse preparations of Khaya senegalensis highlights its significant role in both traditional treatments and pharmacological research.
Parts used
Khaya senegalensis is a medicinal plant that offers various therapeutic benefits through its distinct anatomical parts. Scientific research highlights that the stem, specifically the bark, contains bioactive compounds with cytoprotective and antifeedant properties. Additionally, the leaf extracts have demonstrated significant antimycobacterial activity and antioxidant potential. The root of the plant is also highly valued, as ethanolic extracts from this part exhibit exceptional antioxidative activity and enzyme inhibitory effects. However, traditional practitioners in Mali caution that the bitter stem and root bark should be avoided during pregnancy.
