  • The present paper deals with a preliminary exploration for the studies on background values of 18 elements and 17 amino acids in Chinese"insect herb" (Cordyceps sinensis) by using mathematical method of cluster analysis.From five groups of ghost moths larvae of different instars,four groups of Chinese "insect herb" mycelia were grown on the medium,parasitized larva and the sporocarps of Cordyceps sinensis,were divided into 12 genera.According to coefficients of distance matrix among the samples,the 12 genera originally classified can beg reclassified into 3 genera at 8.66 distance level through cluster analysis.The results obtained are:1.The constituents of fourth and fifth instar larva,on the elements and amino acids,approached that of Chinese "insect herb" (Cordyceps sinensis).2.It is necessary to use the old mycelia of Chinese "insect herb" fungus,grown on the agar medium,or spores of Cordyceps sinensis as a test sample were the most suitable to infect the hepialid larvae.
