Abstract: Extracts of oxidation resistant were got from the leaves of Eucommia ulmoides and Acer truncatum respectively. The extracting rates by different methods were compared. Oxidation resistance of the Leaf Extracts was tested on edible oil. It was found that the extracts of E. ulmoides by using water with room temperature and ethyl acetate as solvents, and the extracts of A. trucatum by using hot water and ethyl acetate as solvents showed high oxidation resistance and extracting yields. A preliminary study was also carried out on the conservation of fresh meat.
