Abstract
BACKGROUND
Tuberculosis is a leading cause of death in the world. A new alternative for the treatment of tuberculosis is urgently required, due to the emergence of multidrug resistant Mycobacterium tuberculosis.
AIM
There is currently considerable interest in developing potential drugs from medicinal plants for treating tuberculosis. To evaluate anti-tubercular activity in the leaves of Kingiodendron pinnatum Rox. Hams., Humboldtia brunonis Wall., Indigofera cassioides Rottl.ex DC., Derris scandens Benth. and Ceasalpinia mimosoides Lamk.
MATERIALS AND METHODS
Non-polar and polar solvent extracts of leaves of these medicinal legumes were tested against M. tuberculosis H37RV and minimum inhibitory concentrations (MICs) were determined by the agar based proportion assay.
RESULTS
Phytochemical screening for secondary metabolites revealed the presence of saponins, steroids, anthro-quinones, terpinods, flavonoids and phlabotanins. Crude leaf extracts of these plants have shown MIC value of 50 μg/ml as against the standard drug Isoniazid value of 0.025 μg/ml.
CONCLUSION
Results showed that crude extracts of legume leaves screened exhibited potential anti-tubercular activity against M. tuberculosis and further work is required to identify the active molecule of these legumes, to get a novel anti-tubercular drug. This is the maiden finding on anti-tubercular activity of these medicinal legumes.
