Effect of S. jambos and T. citrina extracts on the intracellular ROS generation in S. cerevisiae (wild-type and antioxidant mutants, tsa1Δ and sod1Δ) as observed under fluorescent microscope using DCF-DA. (1st row) Untreated wild-type and antioxidant mutants, tsa1Δ and sod1Δ; (2nd row) wild-type and antioxidant mutants, tsa1Δ and sod1Δ treated with H₂O₂; (3rd row) wild-type and antioxidant mutants, tsa1Δ and sod1Δ treated with H₂O₂ and S. jambos; (4th row) wild-type and antioxidant mutants, tsa1Δ and sod1Δ treated with H₂O₂ and T. citrina
