Levels of Selected Chemical Components in Cordyceps sobolifera Fruit Bodies Cultivated Artificially and Collected from the Wild

Levels of selected chemical components in the fruit bodies of artificially cultivated Cordyceps sobolifera fruit bodies were determined and compared with levels in C.sobolifera fruit bodies collected from the wild.Cultivated C.sobolifera fruit bodies contained 31.8% crude protein,4.46% crude fat,17.0% crude fiber,3.36% ash,9.74% polysaccharide,13.3% cordycepic acid,1.27 mg/kg uridine,0.41 mg/kg guanosine and 0.70 mg/kg adenosine.Crude fiber,polysaccharide,cordycepic acid and uridine levels were significantly higher compared with those recorded in wild fruit bodies.However,the former contained lower concentrations of both total and essential amino acids although the proportion of essential to total amino acids was slightly higher in cultivated fruit bodies.
