摘要: 采用微波无溶剂萃取的方法，通过响应面法优化鸡蛋花精油的提取工艺。探索浸润时间，颗粒度，微波提取时间，微波提取功率对鸡蛋花精油得率的影响，优化最佳提取工艺。结果表明，影响鸡蛋花精油提取率的各种因素大小关系为微波提取功率 > 微波提取时间 > 浸润时间 > 颗粒度。提取鸡蛋花精油最佳工艺条件为浸润时间4.00 h，颗粒度40目，微波提取时间33.00 min，微波提取功率470.00 W，此时得率为0.1582%，可得出响应面优化微波无溶剂提取鸡蛋花精油提取率较高，该研究结果以期为鸡蛋花的合理开发提供理论依据。

To explore the effects of soaking time, particle size, microwave extraction time and microwave extraction power on the yield of Plumeria rubra “Acutifolia” essential oil, and to explore the best extraction technology. The results show that the factors affecting the extraction rate of Plumeria rubra “Acutifolia” essential oil are as follows: microwave extraction power > microwave extraction time > soaking time > particle size. The optimum extraction conditions of Plumeria rubra “Acutifolia” essential oil are as follows: soaking time is 4.00 h, granularity is 40.00, microwave extraction time is 33.00 min, microwave extraction power is 470.00 W, and the yield is 0.1582%. It can be concluded that the response surface optimization microwave solvent-free extraction of Plumeria rubra “Acutifolia” essential oil has a higher extraction yield. The results of this study are expected to provide a theoretical basis for the reasonable development of Plumeria rubra “Acutifolia”.
