| Abstract: |
| 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. |
