Abstract

The objective of this study was to conduct phytochemical characterization and antioxidant evaluation of black tea extract (BTE) obtained from Camelia sinensis. Fermented extract from leaves were obtained for phytochemical screening and evaluation of In-vitro antioxidant potential. Phytochemical data revealed the presence of several metabolites, notably from the flavonoid and phenolic class. In the antioxidant activity using the DPPH method, nitric oxide method, superoxide method, hydroxyl radical method and reductive method the enriched extract presented significant IC50 values when compared with ascorbic acid as a standard. These results contribute to the continuity of studies on the chemical and biological composition of the species.
