A novel antioxidative compound, namely 1,1-di-(2′,5′-dihydroxy- 4′-tert-butylphenyl)ethane (DHPE) was synthesized by condensation reaction between tert-butylhydroquinone (TBHQ) and acetaldehyde. The antioxidant and free-radical scavenging activities of this compound were compared to other common antioxidants, namely butylated hydroxyanisole, butylated hydroxytoluene, TBHQ and propyl gallate by 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical assay and oil stability index experiment, deep-fat frying and Schaal oven test. DHPE was the most potent antioxidant among all antioxidants tested using 10% emulsion and deep-fat frying at 180C. It was also a very good antioxidant at room temperature in lard and soybean oil, DPPH radical scavenging assay showed that DHPE was a strong free-radical scavenger. Journal compilation
