| dc.description.abstract | The phytochemical analysis, proximate and mineral analysis, extraction of active principles and antimicrobial susceptibility tests were carried out on Corchorus olitorius Linn. The phytochemical analysis of the plant extracts (aqueous and ethanol) revealed the presence of alkaloids (53.50±0.05 mg), flavonoids (81.38±0.07 mg), tannins (71.00±0.02 mg), saponins (54.70±0.03 mg) and phenols (200.03±16.07 mg). The proximate analysis of whole plant showed that the plant contains moisture (29.69 ±0.01 mg), ash (4.20±0.03 mg), crude fat (7.14±0.01 mg), protein (28.20±0.27 mg), fiber (23.86 ±0.02 mg) and carbohydrate (74.30±0.70 mg). The mineral analysis also showed varied quantities of calcium (616.33±4.73 mg), magnesium (157.50±42.50 mg), iron (1.21±0.01 mg), sodium (306.00 ±6.00) and potassium (233.17±1.61 mg) in the different parts (root, stem, seed and leaves) respectively. Escherichia coli, Staphylococcus aureus, Klebsiella pneumoniae, Salmonella typhi, Microsporum canis, Candida albicans, Aspergillus niger, and Penicillium chrysogenum were the organisms used as challenge organisms in the antimicrobial susceptibility tests. The results of the antimicrobial susceptibility tests showed that the extracts and active principle exhibited inhibitory and bactericidal but not fungicidal activities against the challenge organisms in various degrees. The zones of inhibition of the extracts and active principles on the test bacteria ranged from 4.50±0.1 mm – 10.00±0.07 mm while those of the test fungi were 10.00±0.1 mm. The minimum inhibitory concentrations of the extracts and active principles on the challenge organisms ranged from 100 mg/ml – 250 mg/l while the minimum bactericidal concentration of the extracts and active principles on the test bacteria was 250 mg/ml. This study has justified the traditional use of this plant for the treatment of many bacterial and fungal infections and also as an agent for wound healing whose causative agents are some of these organisms. It also lends credence to the need for further research on this plant so as to fully explore its pharmacological benefits | |
