Antimicrobial activity of Tinospora crispa root extracts

The aim of this study was to determine the in vitro antimicrobial activity of ethanol, distilled water, methanol and chloroform crude extracts of the roots of Tinospora crispa. Antimicrobial activity was examined by disc diffusion method against gram positive bacterial strains of Streptococcus pneumonia, gram negative bacterial strains of Escherichia coli and fungal strains of Candida albicans. The maximum zone of inhibition was obtained with ethanol extract against Escherichia coli and Streptococcus pneumonia followed by chloroform extract against the same organisms. Whilst distilled water extract showed a minimal zone of inhibition, methanol extract showed a moderate zone of inhibition against the bacterial strains used. The values were compared with a standard antibiotic. The ethanol extract also showed the maximum zone of inhibition against the growth of Candida albicans, whereas the lowest activity was shown with distilled water crude extract. Methanol and chloroform crude extracts showed considerably moderate activities against the fungal strain, as compared to the standard antibiotic used.
