23 Jul Microwave-pretreating extraction method for effective component of plant
Abstract
The present invention relates to a method for extracting effective component of plant in separation engineering technology, including the following steps: firstly, pulverizing plant, adding small quantity of aqueous solution containing ethyl alcohol and fully moistening, the placing the moistened pulverized plant material into the microwave field to make rapid pre-treatment, then adding thermal solvent, stirring and washing so as to extract the effective component from said plant tissue. As compared with existent technology its microwave treatment time is short, plant utilization rate is high, and its objective product yield can be raised by above 10%.
