水提法和微波助提法在蛹虫草多糖提取中的应用

摘要

目的:探讨蛹虫草菌丝体多糖提取方法的应用.方法:利用水提法和微波助提法提取蛹虫草菌丝体中多糖成分,利用苯酚-硫酸法测定其多糖的含量.结果:水提法粗多糖的提取率为22.26%,微波助提法的提取率为15.16%.结论:菌丝体粗多糖提取过程中应用传统水提法提取率高,但其工艺复杂、耗时,微波助提法工艺简便、快速.%Objective: To investigate the method applied in the extraction of polysaccharides in Cordyceps militaris mycelia. Methods: Water-extraction method and microwave-assisted extraction method were applied in the extraction of polysaccharides. The content of polysaccharides in mycelia was determined by phenol-vitriol method. Results: The coarse polysaccharides extractive rate of water-extraction method was 22. 26% in Cordyceps militaris mycelia,and the rate of water-extraction method was 15. 16% . Conclusions:The extractive rate of water-extraction method is higher than the rate of microwave-assisted extraction method. But the technology of water-extraction method was complex and time consuming. The technology of microwave-assisted extraction method was simple and speedy.
