摘要:

目的: 探讨水溶性桑叶多糖成分的提取工艺质量控制标准。方法: 用分光光度法测定AB₈树脂提取工艺所得水溶性桑叶多糖的含量。结果: AB₈树脂提取工艺所得水溶性桑叶多糖平均产率为32.96%,其产率平均方差S=2.095,经统计学处理,该工艺所得的桑叶多糖产率没有显著差异(P>0.05).用分光光度法在620nm处,吸光度A值范围在0.598～0.699有药效作用。结论: AB-8树脂提取工艺可作为质量控制标准。

Abstract:

Objective: To study the quality control standard of the water soluble polysaccharide in Sangye (leaf Folium Mori). Methods: The content of water-soluble polysaccharide in Sangye was detected by spectrophotometry and AB-8 resin extraction technique.Results: The average productive rate was 32.96%(s=2.095). There was no obvious difference between the productive rates of polysaccharide in Sangye by using this technique (P>0.05). By spectrophotometry, in 620 nm medicinal effectiveness could be found with 0.598～0.699 in absorbance (A). Conclusion: This technique can be a standard of quality control of polysaccharide.
