摘要
以迷迭香干叶为原料,采用单因素法和正交试验对水蒸气蒸馏法提取迷迭香精油工艺进行优化.结果表明:粉碎时间1 s、蒸馏质量1 kg和蒸馏时间30 min时,迷迭香精油得率达1.86％.采用GC-MS化学成分分析,不同产地提取得到的精油鉴定出12种主要化学成分,并对不同地区精油进行成分对比分析,不同产地迷迭香精油成分最接近西班牙型,但不同产地之间的精油成分存在明显差异.试验为迷迭香精油的提取和应用提供理论和技术支持.
Abstract
The technology of extracting rosemary essential oil by steam distillation was optimized by single factor method and orthogonal test with rosemary dry leaves as raw materials.The results showed that the yield of rosemary essential oil reached 1.86％when the crushing time was 1 s,the distillation weight was 1 kg,and the distillation time was 30 min.By GC-MS chemical composition analysis,12 main chemical compositions of essential oils extracted from different habitats were identified,and the composition of essential oils from different regions was compared and analyzed.The composition of rosemary essential oils from different habitats was most similar to the Spanish type,but the composition of essential oils from different habitats was significantly different.It provides theoretical and technical support for the extraction and application of rosemary essential oil.
