Antioxidant Activity of Forsythin and Forsythiaside A from Forsythia suspensa Leaves on Edible Oils
This study was focused on the antioxidant activity of forsythin and forsythiaside A isolated and purified from leaves of Forsythia suspensa,and the synergistic effect of the two compounds with vitamin C and citric acid as evaluated by acid value and peroxide value (POV) of lard.The results showed that forsythin with purity of 93％ and forsythiaside A with purity of 92％ were obtained and that both of these compounds had concentration-dependent inhibitory effects on lipid oxidation in lard.The inhibitory effect of forsythiaside A was close to that of the positive control 2,6-di-tert-butyl-4-methylphenol (BHT) but the inhibitory effect of forsythin on lipid oxidation was far weaker than that of forsythoside A.Both vitamin C and citric acid exhibited remarkable synergistic antioxidant activity with forsythin and forsythiaside A.
