从废弃蛹虫草大米培养基中高效提取纯化虫草素工艺条件研究

Cordycepin is an important secondary metabolite of Cordyceps militaris, a traditional Chinese medicinal fungus, and is mainly obtained from fruiting bodies at present. This article presents an efficient method of extracting and purifying cordycepin from rice medium, the waste of fruiting body production. The method included 3 steps: continuous countercurrent extraction, column chromatography with 732 cation exchange resin, and crystallization, and their working parameters were optimized. By use of the optim...
