【摘要】 苍耳 (XanthiumSibiricum)是一种很有开发价值的野生油源 ,苍耳籽仁含油量高达 4 5.4 6% ,经气相色谱分析苍耳籽油中脂肪酸以亚油酸为主 ,含量为 65.9% ,油酸含量为 2 0 .8% ,而饱和脂肪酸含量较低。经两次脲包结晶法进行分离分析脂肪酸 ,大部分饱和脂肪酸被包合析出。OSI法测定其氧化稳定性 ,结果显示苍耳籽带壳烘烤后提取的油脂氧化稳定性显著升高。更多还原

【Abstract】 There is 45.46% of oil in xanthium sibiricum seed.Analysis by gas chromatography (GC) showed that xanthium oil contained 65.9% of limoleate,20.8% of oleate and a small amount of saturate fatty acid.Most of the saturate fatty acid was seperated by means of applying urea compleses twice.The result by OSI method showed that the oxidative stability of xanthium oil was obviously raised when unshelled seed had been baked.更多还原
