Preliminary study on dynamic change of polysaccharide contents of Ganoderma-Epimedy fungal substance / 中草药

ABSTRACT

Objective: To investigate the solid fermentation technology for Ganoderma lucidum with Epimedium koreanum containing medium and its practicability. Methods: Four G. lucidum strains were solid fermented in E. koreanum containing medium. The polysaccharide contents of fermented products were tested using phenol-sulphuric acid method. Results: The polysaccharide content of Ganoderma-Epimedy fungal substance was higher than that of G. lucidum in the control medium; By observing the dynamic changes of the polysaccharide contents in the fermented products from the drug-containing medium at different time, it was found that the end point of Ganoderma A-Epimedy was on the day 21 and the fermented terminal point of Ganoderma B, C, and D with Epimedy was on the day 28. Conclusion: Compared with G. lucidum in the control medium, the polysaccharide contents of the fermentative combination of Ganoderma-Epimedy could be significantly improved by 3-13 times.
