ANTIOXIDANT POTENTIAL OF GARCINIA SPECIES FROM SONITPUR DISTRICT, ASSAM, NORTH EAST INDIA
AbstractThe fruits of Garcinia pedunculata Roxb. ex Buch.-Ham., G. xanthochymus Hook. f. and G. morella (Gaertn.) Desr. collected from Sonitpur district of Assam, India were evaluated for the antioxidant potential and total phenolic content. The methanolic extract of these fruits were subjected to DPPH (2,2-Diphenyl-1-picrylhydrazyl) assay for determining the free radical inhibition property and Folin Ciocalteu’s method for quantification of total phenolic content (TPC). G. pedunculata Roxb. ex Buch.-Ham. showed highest antioxidant potential with IC50 value 47.03±13.48 µg/ml. All species contains low phenolic content ranging between 1.83±0.62 to 88.2±2.19 mg GAE/g dry extract. No significant correlation between total phenolic content and antioxidant potential was found.
