Analysis of Phytochemical and Antibacterial Activity of Green Tea (Camellia sinensis) Extracts

Abstract

Green tea is a plant with a high concentration of bioactive compounds based on polyphenols. The major polyphenols in green tea are flavonoids and have four major divisions: epicatechin, epigallocatechin, epicatechin gallate, and epigallocatechin gallate. Humans can easily get infections from bacteria, particularly from contaminated food. Foodborne bacteria such as Salmonella sp., E. coli, Staphylococcus, and Bacillus cereus pose health risks. This study aims to identify the bioactive compounds and effectiveness of Camellia sinensis against E. coli, P. aeruginosa, S. aureus, and B. cereus.
