Abstract
IntroductionThe 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. MethodsAll 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. ResultsAll 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. ConclusionThe 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.
