Total nucleosides in sporophore of \%Ganoderma lucidum \%(Leyss. ex Fr.) Karst produced in different locality was determinated by the UV\|spectrophotometry. The contents of total nucleosides in sporophore of \%G. lucidum \%from Guangxi of China and Viet Nam were 0.33%and 0.34%, the higher contents from Taiwan, Jiangsu and Guangdong were 0.40%～0.46% and lower contents from Yunnan were 0.16%～0.21%. The research proposed a criterion on the quality of \%G. lucidum \%and a brief discussion about its utilization and development. The TLC identification of uracil, adenine, adenosine and uridine in sporophore of \%G. lucidum \%was carried out. The methodological study indicated that the method was simple, reliable and specific.
