Analysis of volatile compounds of mycelia of Hirsutella sinensis, the anamorph of Ophiocordyceps sinensis

In this work, the volatile compound profiles of mycelia of H. sinensis cultured by solid-state media and submerged fermentation were extracted and determined for the first time. Fifty-one volatile compounds were identified in both mycelia. Phenols and acids and alkanes were found as the major classes of compounds. And butylated hydroxytoluene is the most abundant volatile compound in the both mycelia and accounts for 47.38% and 46.12% of the total volatile compounds in the mycelia cultured by solid-state media and submerged fermentation, respectively.
