Abstract:The polysaccharide，triterpenoids，crude protein，soluble protein，ash，and antioxidant activity of 25 wild and domesticated Ganoderma lucidum fruiting bodies were determined using phenol-sulfuric acid extraction，vanillin-perchloric acid-glacial acetic acid colorimetry，Kjeldahl nitrogen determination，Coomassie brilliant blue staining，a muffle furnace，and the 1，1-diphenyl-2-picrylhydrazyl free radical scavenging test coupled to a total reducing power test，respectively.Significant differences in nutritional components were observed between different G.lucidum strains and between the fruiting bodies of the same strain before and after domestication.The polysaccharide and ash contents of most wild G.lucidum strains were higher than those of fruiting bodies after domestication.For example，the maximum polysaccharide content of wild Ganoderma strains was approximately 57.30%，whereas the value was only 49.40% after domestication.The contents of triterpenoids，crude protein，and soluble protein in the fruiting bodies of most strains after domestication were higher than those of wild G.lucidum.For example，the maximum soluble protein content of wild G.lucidum was 6.29 mg/g but only 10.04 mg/g after domestication.The antioxidant activity of water extracts before acclimation was higher than that of after acclimation.
