Chart 4: FRAP assay of fruit extracts of Zanonia indica L.

CONCLUSION: Phytochemical analysis of fruit extracts of Zanonia indica L. assured the
presence of Alkaloids, Flavonoids, terpenoids and Phenols. These were rich in acetone extract

and Methanol extract. Extracts showed the best antioxidant property in all three assays.

Among all extracts fruit acetone extract and fruit methanol extract was very active and
showed positive results for antioxidant assay.
