Abstract

Green tea (Camellia sinensis (L.) Kuntze) is believed to have efficacy as a powerful antioxidant since it contains polyphenols that can reduce free radicals. The aim of this study was to determine the class of chemical compounds of the green tea leaf powder, to characterize the green tea ethanolic extract and to evaluate the antioxidant activity of the green tea ethanolic extract with DPPH method. Green tea was extracted by maceration method using 96% of ethanol and followed by the phytochemical screening, characterization and the antioxidant activity test by DPPH method. The ethanol extract of green tea contained flavonoids, saponins, tannins and steroids / triterpenoids. The moisture content of green tea extract was 14.25%; the total ash was 1.06% and the acid insoluble ash content was 0.099%.The antioxidant activity assay gave 11.83 ± 0.005 µg/ml of IC50. It can be concluded that the ethanol extract of green tea has a very strong antioxidant activity.
