均匀设计优化京万红超临界萃取工艺研究

摘要为确定超临界萃取京万红的最适宜工艺参数，通过U_^*12（12×6×6）均匀设计试验方案，考察压力、温度和夹带剂乙醇浓度的影响。以超临界提取物的出膏率、β, β-二甲基丙烯酰阿卡宁及异欧前胡素含量为目标，采用多因素分析来确定最适宜工艺参数。通过回归分析，确定超临界萃取京万红的最适宜工艺参数为50 ℃，25 MPa，乙醇质量分数95%。

Abstract： U ^* ₁₂ (12×6×6) uniform design was chosen to investigate effects of pressure, temperature, entrainment agents ethanol concentration and to obtain the best parameters of supercritical fluid extraction of Jingwanhong . Optimum process parameters were determined by multivariate analysis according to the extraction ratio and contents of β, β-dimethylacrylalkannin and isomperatorin. Then stepwise regression analysis was performed to obtain the optimum extraction condition: the temperature was 55 ℃, the pressure was 25 MPa, the ethanol concentration was 95%.

Keywords： Jingwanhong uniform design SFE-CO₂ extraction
