Data with different letters (superscript) within the same column are significantly different (p < 0.05).

DPPH = α,α-diphenyl-β-picrylhydrazyl; ETL = ethanol extract of T. triangulare leaves; ETS = ethanol extract of T. triangulare stems; SD = standard deviation; TEAC = Trolox equivalent antioxidant capacity; WTL = water extract of T. triangulare leaves; WTS = ethanol extract of T. triangulare stems.
