Analysis and comparison of volatile components of mycelia of Paecilomyces gunnii and Paecilomyces hepiali
古尼拟青霉和蝙蝠蛾拟青霉发酵菌丝体挥发性成分的分析与比较

The volatile components of mycelia of Paecilomyces hepiali and Paecilomyces gunnii were extracted by simultaneous distillation extraction (SDE) and analyzed by gas chromatography-mass spectrometry (GC-MS). The results indicated that there were 25 and 32 volatile components in mycelia of P. hepiali and P. gunnii, respectively. Butylated hydroxytoluene and 2H-pyrrol-2-one,1,5-dihydro-1-methyl are the two major volatile components in the mycelia of P. hepiali, accounting to 65.78% and 12.77%, respectively. Butylated hydroxytoluene and (E,E)-2,4-decadienal are the two major volatile components in the mycelia of P. gunnii, accounting to 62.11% and 12.32%, respectively. Eight components are in common in liquid submerged fermentation mycelia of the two fungi and make up 71.58% and 69.67% of the total volatile components, respectively, indicating that the major volatile components in the two experimental mycelia are similar. The analysis of volatile components provided a better understanding of the pharmaceutical activities of the mycelia of P. hepiali and P. gunnii.
