摘要
本实验阐述了不同方法对提取桑叶中芦丁含量的影响,通过线性关系实验、精密度实验、重复性试验、稳定性试验、加样回收率试验的检验,同时用水和90.00%乙醇对桑叶分别进行回流、超声和索氏提取的方式来考察不同提取方法对桑叶中芦丁含量提取的影响,其结果为以90.00%的乙醇回流提取1小时提取两次,芦丁提取率最大,所得桑叶中芦丁含量约为5.30%。
The experiment elaborates on the effects of different methods on extracting content rutin from Morus alba. Through linear relation experiment, precision experiment, repeatability experiment, stability experiment and experiment for recovery of the added index. Meanwhile, extract rutin in reflux, ultrasonic method and Soxhlet extraction with water and 90.00 % alcohol. The optimal condition to extract rutin is： use 90 % concentration of alcohol, heated to reflux for 2 hours and 2 times., the content of rutin from Morus alba is approximately 5.30 %.
