超声波辅助浸提黄芪多糖的工艺研究

采用超声波提取技术从黄芪中提取黄芪多糖,筛选出最佳提取工艺。分别考察了乙醇用量、超声波频率、浸提时间、固液比、提取液pH值等因素对多糖提取量的影响,并通过正交试验得到了超声波提取黄芪多糖的最佳工艺参数为:超声波频率为14kHz,提取时间为15min,固液比为3∶80(g∶mL),提取液pH值为8.5,在此条件下,黄芪多糖的提取量为6.223mg/g。

Research the Craft of Extracting Polysaccharides of Astragalus by Ultrasonic

Astragalus mongholicus is a well-known in Chinese traditional medicine. Astragalus mongholicus can increase immune ability and antivirus ability of animals using in animal. The study was to find the optimum parameters in extracting polysaccharides of astragalus by microwave. The single experimental factor was studied,such as ultrasonic frequency,treating time,ratio of solid and liquid and pH of distilling liquid. Then,the optimum parameters were obtained by orthogonal test at ultrasonic frequency 14 kHz,tre...
