超声波辅助提取和热水浸提五味子多糖的比较研究OACSTPCD
Study on the Extraction of Schisandra Chinensis Baill Polysaccharides by Ultrasonic Wave and Hot Water Method
以五味子干粉为原料,对超声波辅助法和热水浸提法提取五味子多糖进行了比较研究,通过正交实验对提取条件进行了优化。超声波辅助提取的最佳工艺参数为提取温度50℃、液料比10∶1、提取时间1h、醇沉浓度80%,平均得率18.61%;热水浸提的最佳工艺参数为提取温度100℃、液料比10∶1、提取时间3h、醇沉浓度80%,平均得率9.35%。同时,采用苯酚-硫酸法对多糖的含量进行了测定,2种方法的多糖含量分别为54.13%和52.38%。超声波辅助提取五味子…查看全部>>
