Table 3.

Comparison (mean ± SD, n = 3) among total phenolic content (TPC) by HPLC-DAD-ESI-QTOF-MS, Trolox Equivalent Antioxidant Capacity (TEAC) and Ferric Reducing Antioxidant Power (FRAP) of Psidium guajava L. leaves at different oxidative states.

Oxidation State	TPC (mg/g leaf d.w.)	TEAC (mM eq Trolox/mg leaf d.w.)	FRAP (mM FeSO₄/mg leaf d.w.)
High	87.91 ± 0.05 ^c	2.2 ± 0.2 ^c	3.69 ± 0.03 ^c
Medium	92.0 ± 0.4 ^b	2.44 ± 0.05 ^b	4.20 ± 0.06 ^b
Low	103 ± 2 ^a	3.1 ± 0.1 ^a	5.4 ± 0.1 ^a

Means in the same column with different letter (^a,b,c) are significantly different (p < 0.05).
