摘　　要：以芳香植物芳香鼠尾草和直立迷迭香鲜样为材料,采用水蒸气蒸馏法,通过单因素试验及正交试验,提升两者的精油提取工艺。其中,芳香鼠尾草最佳提取组合为料液比1∶25(g·mL^(-1))、提取时间0.5 h、提取次数2次,此时精油得率为5.17‰;直立迷迭香的最佳料液比1∶20(g·mL^(-1))、提取时间2 h及提取2次,此时精油得率最高为8.87‰。这一结果可以为芳香鼠尾草和直立迷迭香精油的提取和应用提供理论支持。Fresh samples of aromatic plants such as sage and rosemary were used for the essential oil extraction process optimizing.Single-factor experiments and orthogonal tests were employed within the steam distillation process promoting.The optimal extraction conditions for sage were found to be a liquid-to-solid ratio of 1∶25 g·mL^(-1),extraction time of 0.5 hours,and extraction performed twice,yielding an essential oil rate of 5.17‰.For rosemary,the best conditions were a liquid-to-solid ratio of 1∶20 g·mL^(-1),extraction time of 2 hours,and extraction performed twice,resulting in the highest essential oil yield of 8.87‰.These findings provide theoretical support for the extraction and application of essential oils from sage and rosemary.
