目的:研究用乙醇作夹带剂,采用CO_2超临界法从南方红豆杉中萃取10-脱乙酰巴卡丁Ⅲ的最佳工艺条件;方法:采用正交试验法探讨萃取时间、压力、温度、夹带剂用量对从南方红豆杉中萃取10-脱乙酰巴卡丁Ⅲ的影响;结果:CO_2超临界流体.夹带剂法从南方红豆杉中提取的10-脱乙酰巴卡丁Ⅲ的最佳工艺条件是萃取压力20MPa、萃取温度500C、萃取时间150min、夹带剂用量为20ml/200g原料.此条件下萃取率最高可达到443.342μg/g.

Deliming using CO2 Supercritical Fluid(CO2 SCF) as reactant was investigated, and the effect of the presure, temperature and time on deliming and degrease was studied. The results showed that CO2 SCF can be used as a deliming agent. Deliming usiing CO2 SCF as reactant had some advantages such as more quick, more completely than conventional methods, and can prevent the formation of calcium spot. Furthermore, this new deliming method that avoided...
