高产活性成分蛹虫草菌株的筛选

Screening of Cordyceps Militaris Strains Produced High-yield Active Ingredients

摘要: 对7株不同的蛹虫草菌株进行比较分析，以期筛选得到高产活性成分的优质蛹虫草菌株。通过对7株蛹虫草菌株子实体的形态、产量、子实体中活性成分（虫草素、虫草酸、腺苷、虫草粗多糖）的含量等进行对比研究。结果表明，菌株H05综合品质最好，子实体产量可达20.4 g·瓶^-1，虫草素含量为0.523%、腺苷含量为0.556%、虫草酸含量为4.97%，虫草粗多糖含量为9.89%。此菌株子实体产量高，活性成分含量也较高，经济价值高，值得开发利用。

Abstract: Seven different strains of Cordyceps militaris were compared and analyzed in order to select the high-quality strains of Cordyceps militaris with high-yield active ingredients. The morphology, yield and content of active ingredients (cordycepin, cordycepic acid, adenosine and cordyceps crude polysaccharide) in the fruiting body of the seven strains of Cordyceps militaris were studied comparatively. The results showed that the strain H05 had the best comprehensive quality, and the yield of fruiting body was 20.4 g per bottle, the cordycepin content was 0.523%, adenosine content was 0.556%, cordycepic acid content was 4.97%, and the cordyceps crude polysaccharide content was 9.89%. The strain had high yield of fruiting body, high content of active ingredients and high economic value, and was worthy of development and utilization.
