Abstract

The antioxidant properties of the synthetic compound (C1)-(C8), which comprised 7 curcuminoids and a chalcone, were evaluated by two complementary assays, DPPH and beta-carotene/linoleic acid. It was found that, in general, the free radical scavenging ability of (C1)-(C8) was concentration-dependent. Compounds (C1) and (C4), which contained (4-OH) phenolic groups, were found to be highly potent antioxidants with higher antioxidant values than BHT suggesting that synthetic curcuminoids are more potent antioxidants than standard antioxidants like BHT. Using beta-carotene-linoleic acid assay, only the water-soluble 2, 4,6-trihydroxyphenolic chalcone (C5) showed 85.2 % inhibition of the formation of conjugated dienes reflecting on its potent antioxidant activity.
