Samples	DPPH assay (%)^1	FRAP assay^2	ABTS assay^3
80% methanol
Flesh	31.82 ± 1.29^a	1.95 ± 0.46^c	39.14 ± 2.23^a
Peel	23.94 ± 0.88^c	9.33 ± 0.54^a	40.14 ± 1.76^a
Aqueous
Flesh	29.04 ± 0.73^b	0.67 ± 0.30^c	19.71 ± 1.38^c
Peel	21.76 ± 0.81^c	6.04 ± 1.23^b	27.18 ± 2.29^b

Values are presented as mean ± SD (𝑛=3) which, with different letters (within column), are significantly different at 𝑃<0.05.
¹DPPH free radical scavenging activity was expressed as % of scavenging (𝜇g/mL).
²FRAP was expressed as mM ferric reduction to ferrous in 1 g of dry sample.
³ABTS free radical scavenging activity was expressed as mg ascorbic acid equivalent antioxidant capacity (AEAC) in 1 g of dry sample.
