Fig. 4.
Oxygen radical absorbance capacity (ORAC) values (A) at 1, 2, 5, and 10 μg/mL of different solvent extracts from orange fruit (OF) and orange peel (OP) and at 10 μg/mL of each extracts. E, ethanol; M, methanol; A, acetone. Values are mean with standard deviation. Values not sharing the same letter within OF or OP are significantly different from one another (P<0.05) by Duncan’s multiple range test. ***P<0.001 significantly different between fruit and peel extract by Student t-test.
