【摘要】 通过采用95%乙醇回流脱脂—热水提取—乙醇沉淀的提取方法,在单因子实验的基础上进行正交实验,确定沙棘叶水溶性多糖的最佳提取工艺条件为温度70℃,时间2h,料液比为1∶8.多糖最大得率为24.02%.更多还原

【Abstract】 Polysaccharides in Hippohae rhamnoides L.leaves were extracted by radding fat from 95% ethanol ,hot water extracting, ethanol precipitation. The optimum extractive processing parameters for the active polysaccharide were material/water ratio 1:8,circumfluence temperature 70℃,circumfluence time 2h. The optimum extracting ratio was 24.02%.更多还原
