Fig. 5From: Alkaloid extracts from Combretum zeyheri inhibit the growth of Mycobacterium smegmatis The effects of C. platypetalum alkaloid extracts on mycobacterium in broth. M. smegmatis were grown in broth and exposed to increasing concentrations of C. platypetalum leaf alkaloid extracts in a 96-well microplate. Values are the mean of ± SD for n = 4. *P < 0.05; ** P < 0.01 in comparison with the cells exposed to the zero concentration of extractBack to article page
