| 中文摘要: |
| 研究天然低共熔溶剂（NADES）预处理杜仲翅果提取杜仲胶的工艺条件，在单因子试验的基础上，采用正交试验和响应面试验对工艺进行了优化。结果表明：用氯化胆碱/葡萄糖（物质的量比为1/2）作为NADES时，预处理温度对杜仲胶提取率影响最大，其次为料液比和预处理时间；响应面试验得到的最佳预处理温度为103 ℃，料液比为1/22 g·mL-1，预处理时间为2.3 h，在此条件下验证试验的杜仲胶提取率为13.73%；在此基础上进一步优化回流提取工艺，得到最佳回流提取时间为4 h，提取次数为1，固液比为1/25 g·mL-1，最终全流程杜仲胶提取率达到14.85%。NADES预处理结合回流提取能够显著提高杜仲胶的提取效率，为杜仲胶的高效开发利用提供参考。 |
| 英文摘要: |
| The extraction process conditions of Eucommia ulmoides gum using natural deep eutectic solvents（NADES） pretreatment were investigated.Based on single-factor test，orthogonal test and response surface test were employed to optimize the process.The results indicated that when NADES was composed by choline chloride/glucose with molar ratio of 1/2，the pretreatment temperature had the greatest effect on extraction rate of Eucommia ulmoides gum，followed by the material-to-liquid ratio and pretreatment time.The optimal pretreatment temperature obtained from the response surface test was 103 ℃，the material-to-liquid ratio was 1/22 g·mL-1，and the pretreatment time was 2.3 h，and the extraction rate of Eucommia ulmoides gum was 13.73% in verification test.On this basis，reflux extraction process was further optimized，and the best extraction time was 4 h，the extraction cycle was 1，and the solid-to-liquid ratio was 1/25 g·mL-1.Under the combined optimized conditions，the overall extraction rate of Eucommia ulmoides gum reached 14.85%.NADES pretreatment coupled with reflux extraction could significantly enhance the extraction efficiency of Eucommia ulmoides gum，providing reference for its efficient development and utilization. |
