DPPH | 1.58 ± 0.00a | 7.27 ± 0.05d | 5.43 ± 0.02b | 7.01 ± 0.03c | P < 0.001 |
ABTS | 1.14 ± 0.00a | 4.14 ± 0.00c | 2.26 ± 0.00b | 5.71 ± 0.00d | P < 0.001 |
FRAP | 0.84 ± 0.00a | 6.74 ± 0.02d | 1.67 ± 0.00b | 5.77 ± 0.02c | P < 0.001 |
Note: All the values are mean ± SEM. Mean values with the same superscript letters in the given row are not significantly different whereas those with different superscript letters are significantly (P < 0.001) different as judged by Duncan’s multiple range test. ABTS—2,2′-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid; DPPH—2,2-diphenylpicrylhydrazyl; FRAP—ferric reducing/antioxidant power; LPe–methanol–methanol extract of the lyophilized peel; LPu–methanol–methanol extract of the lyophilized pulp; SDR–ethanol–ethanol extract of the sun-dried rind; and SDS–methanol–methanol extract of the sun-dried seed.
