method and Fe3+ reduction capacity test. On the DPPH model with the best EC50 values of Ethyl
acetate and n-butanol, the EC50 values were 63.73µg/mL and 87.21µg/mL. On the Fe3+ reduction test
model with the best EC50 being Ethyl acetate, the EC50 value was 72.02µg/mL. Bitter leaf is a plant with
the potential for antioxidant capacity and hepatoprotective bioactivity..
