Abstract

|
Free phenolic acid, soluble ester and insoluble phenolic acid were extracted from defatted Crataegus pinnatifida and Terminalia chebula. Their antioxidative effectiveness was compared with BHA and BHT for soybeen oils by measuring peroxide and thiobarbituric acid values at 45℃ for 25 days. The patterns of these extracts were compared by using high performance liquid chromatography. Ether extracts from Crataegus and Terminalia showed a higher antioxidative effectiveness than BHA and BHT, and the latter was more effective than the former. Among phenolic extracts, free phenolic acid and soluble phendic acid ester were found most effective in Crataegus and Terminalia, respectively, Each phenolic extract was confirmed to be composed of two or three individual compounds.
