摘要
采用不同的提取工艺探究对杜仲叶中活性成分含量的影响。本实验对闪式提取法提取杜仲叶中4种主要活性成分的影响因素进行单因素试验考察,确定适宜的提取条件。结果表明,最适的提取工艺为:提取溶剂为70%的乙醇溶液,提取电压为110 V,提取时间为5 min。该工艺为杜仲叶中活性成分的大规模提取提供了有利的理论基础。
In order to Explore the effect of different extraction processes on the content of active components in eucommia ulmoides leaves,the factors affecting the extraction of four main active components from eucommia ulmoides leaves by flash extraction were investigated by single factor test to determine the appropriate extraction conditions. The results showed that, the optimum extraction process was as follows: the extraction solvent was 70% ethanol solution, the extraction voltage was 110 V and the extraction time was 5 min. This technology can provide a favorable theoretical basis for the large-scale extraction of active components from eucommia ulmoides leaves.
