Composition variation of fatty acids in seed oil of Camellia vietnamensis seedling tree
摘要
Abstract
To explore the composition variation of the main fatty acids,seeds which were collected from adult high-yielding Camellia vietnamensis seedling trees were used to extract oil by soxhlet method,and then GC was used to determinate the content of the main fatty acids of the seed oil.The results showed that the content of unsaturated fatty acid reached 86.52％,and the important component was oleic acid whose content accounted for 77.6％,and the variance coefficients of the content of oleic and palmitoleic acids were less than 10％,thus,suggesting goodgenetic stability.The unitary linear regression equations of the content of oleic and linoleic acid,the content of oleic and palmitic acid,and the content of inoleic and palmitic acid were extremely significant,and the unitary linear correlations among the three both showed extremely significantly negative,negative and positive,respectively.The analysis of cluster based on the content of the major fatty acids indicated that 35 high-yielding seedling trees could be clustered into 8 classes(r2＝0.885),meanwhile,the classes were clustered by the interblock differences and the interclass similarity of oleic and linoleic acids.In conclusion,the oleic acid content could be an important indicator in the classification of germplasm and the selection of C.vietnamensis breeding based on the nutritional quality.关键词
