    【Abstract】 The optimal conditions for the extraction of polysaccharide-peptides from Ganoderma lucidum fruitbodies cultivated with grasses were studied. The heavy metal contents in the extract were also determined. The results showed that the optimal rate of fruitbody powder to water , the temperaure and time for extracting polysaccharide-peptides from Ganoderma lucidum fruitbodies cultivated with grasses such as Dicranopteris dichotoma ,Ney raudia reynaudiana and Pennisetum purpureum were 1∶15 ,100℃ and 3h resp.The extraction rate of polysaccharide-peptides from the fruitbodies cultivated with grasses was 1～3 times to those cultivated with log under the same conditions. ......
