ABSTRACT: Natural antioxidants are beneficial for health promoting properties due to its ability to neutralize oxygen contain harmful, DNA-damaging radicals. Fruits and vegetables are good sources of antioxidants. In this study, Bangladeshi seasonal fruits wood apple, jujube, hog plum and elephant apple juice were analyzed for total phenolic content (TPC), total flavonoid content (TFC) and DPPH assay, which are the parameters for determining antioxidant capacity. The study suggests wood apple is a rich source of antioxidants whereas hog plum is a poor source. In addition, jujube and elephant apple were found to have the antioxidant amount equivalent to apple. Moreover, wood apple can be used commercially as a stored antioxidant source.

KEYWORDS: Antioxidant, wood apple, jujube, elephant apple, hog plum, total phenolic content (TPC), total flavonoid content (TFC), DPPH assay, IC50.
