- 摘要:
- 以丹皮为研究对象, 采用单因素试验和正交试验,进行了超声波法和传统热水法提取丹皮多糖的初步探讨, 其中得到了传统热水提取法的最佳工艺条件为浸提温度 80℃、提取时间90 min、料液比 1∶35;超声波提取丹皮多糖的最佳工艺条件:温度 80℃、时间 25 min、料液比 1∶25、功率 200 W、物料粉碎粒度 160 目, 在此工艺条件下, 粗多糖得率为13.6%。 超声波法与传统热水法相比, 提取时间缩短约 2/3, 多糖得率提高 46%以上。
- Abstract:
- Extracting technologies of the polysaccharide of Mudancortex of primary study were finished with a single factorexperiment and the orthogonal experiment in different experimental groups(hotwater and ultrasonic method), the effects ofvarious factors, such as ration of liquid to solid, temperature, extraction time and the grainsize etc.On the producing rate ofthe polysaccharide of Mudancortex were compared at givenconditions.The optimal conditions with traditional methodwere:Extraction temperature 80℃, heating time 90 min, the material fluid ratio was 1∶35, grainsize 80 mesh.The optimal condi-tions with ultrasonic method were:Extraction temperature 80℃, ultrasonic time 25 min, the material fluid ratio was 1∶25,power 200 W, grainsize 160 mesh, under this technological conditions, the thick polysaccharide rate was 13.6%;Comparedwith traditional hot water extraction method, the ultrasonic method could shorten the time of two-thirds and increase thepolysaccharide extraction rate above 46%.
