Abstract:
The effect of storage time on the contents of polysaccharides,mannitol,total flavonoids,and 7 nucleosides (uracil,uridine,inosine,guanosine,adenine,adenosine and cordycepin) in fresh Cordyceps militaris were studied in this paper.The results suggested that the colour of the stroma of C.militaris turned from orange to dark orange,eventually turned black,and the mushroom flavor of samples turned into a rotten smell with the increasing of treatment duration.The storage time had an obvious influence on the chemical components of C.militaris,and the changes rule of chemical components in C.militaris were summarized as follows,the content of polysaccharides first decreased and then increased,however，the content of total flavonoids was increased in initial stage and then declined,the content of mannitol decreased gradually；in addition,the contents of uracil and adenine increased with the time increasing,on the contrary,the levels of adenosine,cordycepin and guanosine decreased gradually,the contents of uridine and inosine increased at first and decreased after a period of time,the cubic curve-fitting equations could be used to describe the changes of chemical components in fresh C.militaris with storage time.The results indicated that the changes of the contents of polysaccharides,mannitol,uracil,adenine,adenosine and cordycepin could be used as the quality control indexes of fresh C.militaris.
