摘要
采用超临界二氧化碳萃取技术 ,研究了岩蔷薇的萃取工艺。探讨了温度、压力、时间及CO2 流量等因素对萃取物得率的影响 ,采用四因素四水平的正交设计 ,得出超临界二氧化碳萃取最佳工艺条件为 :压力 2 8MPa、温度 40℃、时间 3h、流量 3 0L/h ,萃取物得率为 6.6%。产品质量优于有机溶剂萃取法。
The extraction technique of Labdanum was studied by supercritical carbon dioxide extraction method.Factors affecting extraction yields,such as pressure,temperature,time and CO 2 flow rate were disscussed.By orthogonal experiment,the optimum technological condition were obtained as follows:pressure 28MPa,temperature 40℃,flow rate 30L/h and time 3h.The extraction yields was 6.6,its quality was better than by organic solvent extraction.
