Abstract
Traditionally, Camellia sinensis and Terminalia arjuna are being used widely to cure various diseases like cardiovascular diseases, cancer etc. In the present study, extracts of these plants were evaluated for their antimicrobial activities against some human pathogenic bacteria viz. E. coli, P. aeruginosa, S. aureus and fungus C. albicans. In-vitro inhibition of these pathogenic microorganisms produced inhibition zone ranging from 9 to 18 mm. MIC values of these plant extracts ranged from 6.25 to 12.5 mg/ml. MBC of C. sinensis for E. coli, P. aeruginosa and S. aureus was found to be 50 and 12.5 mg/ml, respectively. In case of T. arjuna, the MBC of all the tested microorganisms was found to be 25 mg/ml. The MFC of C. sinensis and T. arjuna against C. albicans was observed to be 50 and 25 mg/ml, respectively. GC-MS analysis of C. sinensis and T. arjuna extract identified 13 and 21 compounds, respectively.
