Comparison of polysaccharides and triterpenes contents ofthe mycelium of Ganoderma Lucidum in solid-state fermentation

According to the contents of polysaccharides and triterpenes, the differences of the contents of bioactive substances of 8 Ganoderma lucidum myceliums prepared by solid-state fermentation were studied. The results showed that there were obvious differences in the production of mycelia, the contents of polysaccharides and triterpenes between the strains. G. japonicum had the maximum production of mycelia, achieved 21.66% and the polysaccharides contents of Coriolus versicolor was highest amounted to 8.16%. The triterpenes contents of G. lucidum and G. applanatum were higher, reached 1.13% and 1.08% respectively. G. japonicum had the highest polysaccharides yield of 0.996%, and G. lucidum had the highest triterpenes yield of 0.173%. Therefore, solid-state fermentation is a good method to product polysaccharides for G. japonicum and to product triterpenes for G. lucidum.
