| 摘 要： | 采用均匀设计对连翘中熊果酸的提取工艺进行考察,以乙醇浓度、提取时间、液固比、提取次数为考察因素,采用U7(7)4表进行实验,根据多元回归方程得到最佳提取工艺为:乙醇浓度为75%,其加入量为原料的7倍,提取2次,每次60 min.

| Abstract: | Uniform design method was adopted to research the extraction of ursolic acid.The ethanol concentration, the extraction time, the liquid to solid ratio and the extraction times were researched by U 7(74).The optimal conditions were achieved by optimization treatment and confirmed by experiment:the ethanol concentration being 75%,liquid to solid ratio being 7,extraction time 60 minutes,extracted two times. |
