Antioxidant Efficacy of Selected Underutilized Fruit Species Grown in Sri Lanka

The present study was carried out to determine the vitamin C content, total phenolic content (TPC), antioxidant efficacy and monomeric anthocyanin (TMAC) of twenty-one underutilized fruit species grown in Sri Lanka. Approximately 5g homogenates used while lyophilized aqueous extracts were perform in-vitro assays. Folin-Ciocalteu’s colorimetric assay TPC. 2,2-diphenyl-1-pycrylehydrazyl (DPPH) radical scavenging, 2,2’- azinobis- 3- ethylbenzothiazoline-6-sulphonic acid (ABTS) activity ferric reducing power (FRAP) assays extracts, pH differential method TMAC. highest TPC (104 mg gallic equivalents/g on dry weight (DW) basis), (155?mol ferrous sulphate DW), lowest IC50 (0.0004 g DW/mL) recorded Phyllanthus emblica obtained first rank overall antioxidative properties among tested species. Fruits with Flacourtia indica, Morus alba, Syzygium caryophyllatum. TMAC found S. caryophyllatum (79 cyanidin-3-glucoside (C3G)/g DW) Elaeocarpus. serratus (0.29 C3G/g DW).
