IN-VITRO ANTIOXIDANT PROPERTIES OF DELONIX ELATA WHOLE PLANT EXTRACTS
AbstractDelonix elata (D. elata) whole plant was chosen to evaluate in-vitro anti-oxidant activities. The total polyphenols and flavonoids were determined after the extraction. DPPH (2, 2′-diphenyl-1-picrylhydrazy), H2O2 (Hydrogen peroxide), NO (Nitric oxide) and TBARS (Thiobarbituric acid) methods were used to evaluate antioxidant activities of D. elata whole plant. The results showed that the highest levels of polyphenols were recorded in DEM (15.32 ± 0.32 mg of GA/g of extract). Total flavonoid contents of extracts/fractions showed that DEM (15.57 ± 0.69 mg of Qu/g of extract) contains the highest level. The DEM extract shows more inhibition of DPPH (92.56), NO (143.88), H2O2 (182.28) and TBARS (121.94 µg/ml), respectively when compared with other extracts. These findings suggest that the extracts obtained from D. elata stem have active substances contributing to the increase in natural antioxidant potential. It can be concluded from the findings that D. elata extracts have potent antioxidant potential.
