Acornic powder was extracted with methanol and ethylacetate to obtain a crude acornic compounds. And they were examined concerning their antioxidant activities for linoleic acid. The results were as follows: 1. Hydrogen donating activity for DPPH was higher in 100ppm acornic compound than 100ppm BHT and 100ppm ${\alpha}$-tocopherol. 2. When the 100ppm acornic compound was added to linoleic acid, which was heated at $50^{\circ}C$ for 48 hours, antioxidant activities by POV and TBA was higher than that of 100ppm ${\alpha}$-tocopherol, but the effect was almost the same as the 100ppm BHT. 3. Antioxiodant activity of acornic compound showed synergistic effect along with malic acid, citric acid, tartaric acid, alanine, arginine, histidine, lysine-HCl, galactose, maltose, glucose and sucrose. 4. Acornic compound inhibited peroxidation of linoleic acid induced by heavy metals.
