中文摘要:
      为了研究引种的6个长林系列油茶在温州地区的品质情况，对6个长林系列引种油茶种仁含油率及脂肪酸组成进行检测。结果表明：6个长林系列油茶种仁含油率由高到低分别为45.2%、45.1%、42.7%、42.0%、38.4%、33.8%；总饱和脂肪酸含量最低的为长林4和长林166（均为104%），最高的为长林53（12.9%），平均含量11.3%；单不饱和脂肪酸中油酸含量最高的为长林4（823%），最低的为长林40（73.2%），平均含量为78.0%；同时还检测到少量的对人体有益的角鲨烯和β-谷甾醇。从含油率高、单不饱和脂肪酸含量高、多不饱和脂肪酸含量低来看，长林4的品质最优。
英文摘要:
      In order to study the quality of six Changlin series of Camellia oleifera in Wenzhou region, the oil content and fatty acid composition of six Changlin series of Camellia oleifera kernel were tested. The results showed that the oil contents of Camellia oleifera kernel in six Changlin series from high to low were 45.2%, 45.1%, 42.7%, 42.0%, 38.4% and 33.8%, respectively. The lowest total saturated fatty acid content was 10.4% for Changlin 4 and 166, and the highest content was 12.9% for Changlin 53, and the average content was 11.3%. The highest oleic acid content was 82.3% for Changlin 4,and the lowest content was 73.2% for Changlin 40,and the average content was 78.0%. A small amounts of squalene and β- sitosterol were detected,which were beneficial to human body. Changlin 4 had the best quality according to the high oil content, high monounsaturated fatty acid and low polyunsaturated acid.
