Abstract: In the article, oxidization-inhibited constituents obtained from the seed-shell of korean pine by the supercritical CO₂ extraction method was studied, and the relationship, between the oxidization-inhibited constituents and the processing parameters including the pressure, the time and the temperature was also analyzed. It was concluded that the optimial conditions were as follows: the pressure 40 MPa, the temperature 35℃ and time 120 min,by which gave a yield of 2.4%. And there were 42.1% of the extract were constituents,with anti-oxidation ability stronger than others. In addition,the constituents extracted from the seed-shell of korean pine had the obvious anti-oxidation to the edible soybean oil and a dose-effect relationship between the adding arnount and anti-oxdation effect was found. As the addition of 0.6%, the oxidation resistance was the best.

Key words: korean pine, the seed-shell, supercritical CO₂ extraction, anti-oxidation
