| 摘要: |
| 采用水蒸气蒸馏法提取龙脑型阴香叶片精油，并用气质联用法检测分析 2018 全年各月含油率
及主要化学成分的含量变化。研究结果发现，全年各月精油所含化学成分主要为次生代谢产物，有 30-40
种，主要为萜烯类、萜醇类和酯类化合物；不同月份精油及右旋龙脑含量分别达极显著和显著差异；而
不同季度中精油含量达极显著差异，右旋龙脑含量无显著差异，表明选择合适的月份 / 季节采收枝叶，可
以显著提高精油和右旋龙脑的产量。多重比较显示 10-12 月（冬季）精油含量最高，右旋龙脑含量在 7-9
月（秋季）最高。综合精油和右旋龙脑含量两个因素测算，建议在冬季（即 10-12 月）进行枝叶采收可以
提高经济效益。精油中非右旋龙脑成分含量年度内在 44.27%~71.00% 之间，具有相当的比重，含量较高
的化学成分如桉树脑等均是医药、日化和化工产品的重要原料，综合开发利用桉树脑等重要成分，可提
高收益。 |

| Abstract: |
| The essential oil of the leaves of Cinnamomum burmannii chvar. Borneol was extracted by steam
distillation, and the change of oil content and main chemical components in each month of 2018 was detected and
analyzed by GC-MS. The results showed that the chemical composition of essential oil was mainly secondary
metabolites about 30-40 kinds, mainly terpenes, terpenols and esters; the content of essential oil and D-borneol in
different months showed very significant and significant differences, while the content of essential oil in different
seasons showed very significant differences, but the content of D-borneol had no significant difference, so that the
yield of essential oil and D-borneol could be significantly increased by selecting the appropriate month / seasonfor harvesting branches and leaves. Multiple comparisons showed that the content of essential oil was the highest from October to December (winter), but the content of D-borneol was the highest from July to September
(Autumn). According to the estimation of essential oil and D-borneol content, it is suggested that the economic
benefits can be improved by harvesting branches and leaves in winter (from October to December). The content
of non-d-borneol composition in essential oil is between 44.27% and 71.00% in different months, which has a
considerable proportion. These chemical components with higher content, such as 1,8-cineole, are important raw
materials in medicine, daily chemical industry and chemical industry. We should pay attention to development and
utilization of 1,8-cineole and other important components as by-products to improve the income. |
