Abstract: In order to find out the variation rules of polysaccharides and triterpenes contents of fruit-body of Ganoderma lucidum in different growth and development periods, provide the theoretical basis for the breeding special strains for extraction and processing and the choice of harvest time of fruit-body, Polysaccharides and triterpenes contents of fruit-body of different strains of Ganoderma lucidum in different growth and development periods were determined. The results showed that the difference of polysaccharides contents of fruit-body of the great mass of strains of Ganoderma lucidum among different growth and development period was remarkable, and the difference of triterpenes contents was remarkable also. Polysaccharides contents of fruit-body of Ganoderma lucidum was highest in budding period, lower in fruit-body growing period, higher in maturing period and lowest in effete period. Triterpenes contents of fruit-body of the great mass of strains of Ganoderma lucidum in budding, growing, maturing period was kept in a higher level, and in effete period was reduced drastically. Harvest in good time during maturing period was the best way to prevent the lapse of the effective constituents, such as polysaccharides and triterpenes. Not only to breed the strain that polysaccharides and triterpenes contents are both higher, but also to select the strain that the effective constituents are kept in a higher level in the evening of the life of Ganoderma lucidum.
