  • The purpose of this study was to determine the antioxidant activity of fermented tea (black tea) with Ketapang leaves (Terminalia catappa) using two variations of leaf age, namely leaflets 1-3 and 4-5. The parameters observed were water content, pH, antioxidant activity (IC 50) and total phenol content of tea. Results showed that the antioxidant activity of young leaves (shoots 1-3) significantly higher than old leaves (shoots 4-5) but had lower total phenol and pH. In general, the character of Ketapang leaf tea products at shoots 1-5 has water content ranging from 5.55-5.58%, total phenol content of 22.63-28.97 mg / g EAG, and antioxidant activity (IC 50) of 6.27-6 .71 μg/ml and the pH of steeping water from 5.9 to 6.1.
