摘要: 采用CO2超临界萃取分别对柚子籽、桔子籽、樟树籽、哈密瓜籽、西红柿籽和茶叶树籽等6种果仁提取它们的油脂,并用气相色谱法分析它们各自脂肪酸组成。萃取结果表明,上述各油料均有较高的出油率,出油率在22%以上。脂肪酸含量分析结果表明,它们的亚油酸含量较高(大于25%),其中哈密瓜籽仁的亚油酸含量高达64.19%。根据测定结果对它们的开发前景作了讨论。

Abstract: The oils of teak seeds, citrus seeds, camphore tree seeds, Hami melon seeds, tomato seeds and tea tree seeds were extracted by supercritical CO2 fluid . The components of fatty acids were analysied by GS. The results of extraction show these seeds had higher oil contents which were about 35% and the analysis show higher linolic acid content which of Hami melon seeds was as high as 64.19%. Their exploitable prospect were discussed according to the testing result.
