| 摘 要： | 采用U11(1110)均匀设计试验优选超临界-CO2 提取苦瓜总皂苷和黄酮的最佳工艺条件。分别以苦瓜中总皂苷和黄酮含量为指标探讨萃取压力、温度、萃取时间和夹带剂(无水乙醇)用量等因素在不同水平下对苦瓜皂苷和黄酮提取工艺的影响，确定苦瓜皂苷和黄酮超临界-CO2 流体萃取最佳工艺参数。苦瓜皂苷的最佳萃取条件为萃取压力25.5MPa、温度42.5℃、夹带剂用量180mL；苦瓜黄酮的最佳萃取条件是压力27.5MPa、温度39.5℃、夹带剂用量226mL。萃取时间均为3h，采用一级分离，分离温度均为35℃。

| Abstract: | The supercritical carbon dioxide fluid extraction(SFE-CO2) was adopted to extract total momordicosides and total flavones from Momordica charantia L.fruits.Two sets of parameters for extracting total momordicosides and total flavones were optimized to maximize their yields using a U11(1110) uniform design and two regression models decribing the effects of extraction pressure and temperature and amount of added modifier(absolute ethanol) on the extraction of total momordicosides and total flavones were built... |
