STUDY ON THE ANTIOXIDANT ACTIVITIES OF THE AERIAL PARTS AND SOME COMPOUNDS ISOLATED FROM Archidendron clypearia ((Jack) I. Niels Part 1. THE ANTIOXIDANT ACTIVITIES OF EXTRACTS FROM Archidendron clyperia (Jack) I. Niels
Abstract
The antioxidant activity of Archidendron clypearia was evaluated by different methods, including in vitro biological tests on liver cells of rats, total antioxidant activity and DPPH assay for free radical scavenging capacity. The curcumin standard, a typical antioxidant compound, was also compared. The extract and fractions of Achidendron clypearia had significant antioxidant properties with absorbance value, ED50 and IC50 value. Among five fractions, the ethyl acetate fraction brought the highest activity with the lowest ED50 value of 0.63 µg/mL (about 6 times lower compare to the ED50 of curcumin (4.43 µg/mL)) and IC50 value of 1.81 (20 times lower compare to the IC50 of curcumin).References
