ABSTRACT The present study was aimed to evaluate the antioxidant potential of the methanol extracts of Carica papaya fruits using thermal and non thermal methods of extraction . Preliminary phytochemical studies , determination of total phenolic and flavonoid contents and DPPH radical scavenging assay were performed . Preliminary phytochemical screening of the extracts showed presence of alkaloids , flavonoids , tannins and phenolic compounds . The total phenolic and flavonoid contents revealed higher concentration in the extract prepared by cold maceration process than its counterpart , with higher percentage of scavenging DPPH radical . Thus , it may be concluded that application of higher temperature during extraction process affects the phytoconstituents of C . papaya fruits .
