摘　　要：采用压榨法提取不同树龄的山柚油,以GC-MS分析鉴定其化学成分。从不同树龄山柚油中共鉴定出31个化学成分,其中饱和脂肪酸以软脂酸和硬脂酸计其相对含量随着采样树龄的增加从39.3→36.7→37.2→ 29.6而逐渐降低;不饱和脂肪酸以油酸和亚油酸计其相对含量随着采样树龄的增加从56.5→58.7→59.1→ 67.1而逐渐增加。说明山柚树的生长周期对山柚油的化学成分变化产生趋势性贡献,本研究为山柚油合理开发利用提供了数据支撑。The Camellia oleifera oil is extracted by mechanical pressing and then analyzed by GC-MS. 31 compounds are identified from Camellia oleifera oil of different aged trees. The relative content of saturated fatty acids, calculated by palmitic acid and stearic acid, decreased gradually with the increase of sampling tree age from 39.3→36.7→37.2→29.6;the relative content of unsaturated fatty acids, calculated by oleic acid and linoleic acid, increased gradually with the increase of sampling tree age from 56.5→58.7→59.1→67.1. These results demonstrate that tree ages affect the chemical constituents of Camellia oleifera oil. It provides experimental basis for the development of Camellia oleifera oil.
