摘 要:在单因素试验基础上,以压力、时间、温度为响应因子,以β-石竹烯提取率为响应值,采用响应曲面法进行工艺优化预测,对依兰香中β-石竹烯的超临界CO2提取工艺进行优化。试验表明,影响β-石竹烯提取率的各因素的影响力由大到小顺序为压力、温度、时间,最佳提取工艺条件为提取压力369 MPa、提取温度60℃、提取时间4 h,此时β-石竹烯提取率为0.903 8%。验证试验结果与模型预测值基本相符,表明该工艺可用于依兰香中β-石竹烯的提取。On the basis of single factor experiments,pressure,time and temperature were selected as response factors,the extraction rate of β-caryophyllene as response value,response surface methodology was adopted to optimize the extraction conditions of β-caryophyllene,the supercritical fluid extraction( SFE) conditions of β-caryophyllene from Cananga odorata were optimized. The results revealed that the impact factors on the extraction rate of β-caryophyllene sequenced in a descending order were pressure,temperature,time. The optimal extraction conditions were as follows: pressure 369 MPa,temperature 60 ℃,time 4 h,the extraction rate of β-caryophyllene was 0. 903 8%. The results of verified experiment were in accordance with prediction results by model,and this technology can be used in the extraction of β-caryophyllene from Cananga odorata.
