Abstract: Bunchosia armenica being a member of family “Malpighiaceae” is an edible red-coloured fruit and a source of bioactive compounds. In this study, fruit of Bunchosia armenica was analysed to investigate antioxidant properties and total polyphenol content. DPPH assay (IC₅₀ value) and Folin-Ciacalteu method calculated as Gallic acid equivalents (GAE) were carried out. Reducing power of peanut butter fruit extract was checked as a qualitative test to confirm presence of antioxidant substances in peanut butter fruit extract.Total phenol content of flesh of peanut butter fruit was obtained as a mean of 33.27mg Gallic acid equivalents per L of fruit extract. In DPPH radical scavenging assay, the IC₅₀ value in peanut butter fruit variety was obtained as 13.44±0.29mg/ml. In the analysis of reducing power in peanut butter fruit extract, colour changed into green by confirming the presence of antioxidant substances.
