【摘要】 为了开发利用桑叶中水溶性多糖的药用功能 ,在单因子基础上进行正交试验 ,进一步优化了桑叶水溶性多糖的提取工艺 :烘干的桑叶粉质量浓度为 0 0 4 0g/mL ,在 75℃水浴中提取 2次 ,抽提 6 0min ,提取液用 80 % (终体积分数 )乙醇醇析。在此最佳提取工艺下 ,多糖得率为 2 5 0 8%。更多还原

【Abstract】 Based on the single factor test, orthogonal intersection test, the extraction technology of water soluble polysaccharide from the mulberry leaf was studied. When the mass concentration of mulberry leaves was 0 040 g/mL in water and bathed for 60 min at 75 ℃, then precipitated with 80%( eventually volume fraction) ethanol, a high yield of polysaccharide was 2 508%.更多还原
