Researches in recent years reveal that it contains varieties of components, e.g. carbohydrates, amino acids, nucleosides, acids lipids, minerals, vitamins and so on.

     

    a.    Carbohydrates

    Cordyceps sinensis is a polysaccharose substance with mannite constituting 48.15 %, glucose 5.04 % and galactose 22.13 %.

     

    b.    Amino acids

    It contains over 20 amino acids, such as aspartic acid, lysine, glutamic acid, cystine, alanine, threonine, proline, tyrosine, leucine, citrulline, arginine, serine, etc.

     

    c.    Nucleosides

    An antibiotic substance extracted from the caterpillar fungus culture was named cordycepin, whose structure was 3-deonucleoside. The adenosine extracted from the caterpillar fungus zymotic fluid was 0.28 %.

     

    d.    Acids lipids

    Analyses show that Cordyceps sinensis contains palmitic acid, oleic acid £]-linoleic acid, stearic acid, etc. The content of hexadecyl acid is 21.65 %, 1.1-diphenyl hydrazine 0.07 %, 12~18 carbon 36.11 %.

     

    e.    Minerals

    Cordyceps sinensis contains more than 20 minerals, such as P, Mg, Fe, Ca, Al, Si, Zn, Mn, Se, Cu, Ti, Cr, etc.

     

    f.     Vitamins
