Abstract

This study investigated the effects of different percentages of ethanol (0 - 100) extraction times (1 - 5 h) and temperatures (25 - 60C) on total phenolic content (TPC) and antioxidant activity (AA) of sapodilla pulp and peel. TPC was determined by Folin-Ciocalteu reagent method while AA was evaluated using 2 2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay 2 2-azino-bis-(3-ethyl-benzothiazoline-6-sulfonic acid) (ABTS) radical scavenging assay ferric reducing antioxidant power (FRAP) assay and -carotene bleaching (BCB) assay. Based on the optimal extraction conditions used sapodilla pulp extract had TPC of 3.89 mg GAE/g 63.20 of DPPH scavenging activity 4.30 of ABTS scavenging activity 19.17 of BCB activity and FRAP value of 15.24 mg TE/g; while its peel extract had TPC of 9.23 mg GAE/g 92.95 of DPPH scavenging activity 5.36 of ABTS scavenging activity 8.14 of BCB activity and 27.85 mg TE/g (FRAP value). Using the optimal extraction conditions for sapodilla pulp (40 ethanol as extraction solvent that extracted at 60C for 4 h) and sapodilla peel (80 ethanol and 2 h extraction time at 40C) highest antioxidants can be extracted from the pulp and peel.
