Abstract:

The aim of the present investigation is to study the antibacterial activity of different green tea leaves subjected for solvent extraction against seven clinically isolated antibiotic resistant bacteria. Different types of tea leaves such as mother, scale (cataphyll), first, second and third and buds of tea plant were extracted successfully with petroleum ether, ethyl acetate and chloroform and tested for their antibacterial activity by well diffusion method. The results showed that a remarkable antibacterial activity of green tea samples of first and second leaves followed by leaf bud against the tested organisms was recorded.  However zone of inhibition is moderate in third leaf and mother leaf which may be due to several factors including origin of tea leaves, vegetation habits, age of the leaves and extract preparation. Ethyl acetate extract of tea leaves was found to be the most effective against human pathogenic organisms in terms of growth inhibition.


Keywords: Tea leaves, Camellia sinensis, Antibacterial activity, Antibiotic resistant bacteria.
