Comparative in vitro antibacterial evaluation of different extracts of Camellia sinensis leaves form different geographical locations in India
Abstract:
Introduction: The present study was conducted to assess and compare the in vitro antibacterial property of four different solvent extracts from Camellia sinensis> (tea) leaves collected form five different geographical regions of India. Methods: All the extracts at the concentration of 4 mg/ml was tested for their in vitro antibacterial potential by cup plate method against Bacillus subtilis, Staphylococcus aureus, Escherichia coli and Staphylococcus epidermidis. Results: All the test tea extracts were found to exhibit remarkable antibacterial effect except against S. aureus. The tea sample form Assam was found to be the most active. Conclusion: The marked and differential antibacterial effect of C. sinensis leaf from different Indian locations was plausibly due to geographical variations in chemical constituents especially polyphenol contents of C. sinensis leaf.
