Abstract：Objective Volatile compounds of Paecilomyces hepiali in submerged culture were analyzed. Methods Volatile compounds of Paecilomyces hepiali in submerged culture were collected by headspace solid phase micro - extration (HS - SPME),and separated and identified by gas chromatography mass spectrometry(GC/ MS). Results A total of iden-tified 48 kinds of chemicals,pyrazine and the highest relative content,aldehyde compounds accounted for 46. 7% and 44. 4%of the total. 48 species of chemical compounds in the powder were identified,including 2 - methyl - butanal(29. 41% ),3 -ethyl - 2,5 - dimethyl - pyrazine(9. 19% ),2 - methyl - propanal(6. 57% ),2,5 - dimethyl - pyrazine(5. 96% ),2 -ethyl - 6 - methyl - pyrazine(5. 35% ),2 - ethyl - 5 - methyl - pyrazine(4. 35% )and 2 - ethyl - 3 - methyl - pyrazine (4. 08% ). Conclusion HS - SPME - GC/ MC was an effective method for identifying volatile compounds in Paecilomyces hepiali in submerged culture.
