| 中文摘要: |
| 为探明不同种源地香叶树作为油料树种的开发价值，采集了全国6省20县市的香叶树果实，对香叶树全果、果肉及籽的油脂含量及脂肪酸组成进行了分析，并采用ward法对不同种源地香叶树籽油脂肪酸进行了聚类分析。结果表明：香叶树全果、果肉以及籽的平均油脂含量分别为43.31%、42.38%及46.12%；全果油脂肪酸组成以月桂酸、油酸和癸酸为主；果肉油以油酸和棕榈酸为主；而籽油则以月桂酸和癸酸为主，月桂酸含量为53.20%~70.30%，月桂酸和癸酸总含量达76.40%~90.10%；聚类分析将不同种源地香叶树分为3大类，云南省、贵州省及广西省的香叶树属低月桂酸类型，福建省、江西省及湖南省的香叶树属中高月桂酸型。香叶树可作为生产中碳链脂肪酸的新晋树种，福建省的香叶树籽油脂含量高，且籽油中月桂酸含量高，作为中碳链脂肪酸的原料地具有明显的开发优势。 |

| In order to investigate the development value as oil tree species of Lindera communis Hemsl.from different provenances, the fruits of Lindera communis Hemsl. were collected from 20 counties and cities in 6 provinces across China, and the oil content and fatty acid composition of the whole fruit, pulp and seed were analyzed. In addition, the ward method was used for cluster analysis on the fatty acid composition of the seed oil. The results showed that the average oil contents of the whole fruit, pulp and seed of Lindera communis Hemsl. were 43.31%, 42.38% and 46.12%, respectively. The fatty acid composition of the whole fruit oil was dominated by lauric acid, oleic acid and capric acid; the pulp oil was mainly composed of oleic acid and palmitic acid; while the seed oil was dominated by lauric acid and capric acid, with the content of lauric acid ranging from 53.20% to 70.30% and the total content of lauric acid and capric acid reaching 7640%-90.10%. The cluster analysis divided the Lindera communis Hemsl. into three categories, with those in Yunnan, Guizhou and Guangxi provinces being of the low lauric acid type, and those in Fujian, Jiangxi and Hunan provinces being of the medium-high lauric acid type. Lindera communis Hemsl. could be used as a new tree species for the production of medium-carbon chain fatty acids. The Lindera communis Hemsl. in Fujian province had obvious development advantages for medium-carbon chain fatty acids for its high oil content in seed and high lauric acid content in the seed oil. |
