Evaluation of antimycobacterial activity of medicinal plants used by Malian traditional medicine practitioners to treat tuberculosis
International Journal of Biological and Chemical Sciences(2021)
摘要
Global Tuberculosis (TB) control is facing major challenges such as occurrence of multidrug-resistant (MDR) and extensively drug-resistant tuberculosis (XDR). The current TB drugs are getting less effective and associated with side effects limiting their use, especially with MDR and XDR infected patients. In Mali, many medicinal plants are used against various diseases including bacterial infections. The study aimed at studying the antimycobacterial activities of 60 extracts from 22 Malian medicinal. The antibacterial activity against Mycobacterium tuberculosis H37Rv was assessed employing micro-broth dilution method. Out of 60 extracts evaluated, eleven from nine different plants were found to be active against H37Rv strain. The minimal inhibitory concentrations (MICs) ranked from 125 μg/mL to 1250 μg/mL. The most active extracts (125 μg/mL) were represented by ethanolic extract of Saba senegalensis and Vitellaria paradoxa leaves, dichloromethane extract of Cola cordifolia leaves, Strychnos spinosa and Ximenia Americana roots. Ethanolic extract of Zizyphus mauritiana, Guiera senegalensis and methanolic extract of Anthocleista djalonensis also prevented the growth of H37Rv at 250 μg/mL. The results suggest that Saba senegalensis, Vitellaria paradoxa, Cola cordifolia, Strychnos spinosa and Ximenia Americana could be potential sources of antimycobacterial molecules
