摘要： 对超临界CO2萃取红松种壳中的抗氧化成分进行了研究。分析了其抗氧化成分与超临界CO2提取的压力、时间、温度之间的关系,得出超临界CO2萃取红松种壳中抗氧化性物质的最佳条件为压力40 MPa 、温度35℃ 、时间120 min,萃取物得率为2.4%,抗氧化性较强部分占其中的42.1%。并且发现红松种壳提取物对豆油具有明显的抗氧化作用,并具有剂量效应的关系,在添加量为0.6%时抗氧化效果最好。

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
