Abstract:

Abstrat :Volatile organic compounds of cedar leaf were identified by using solid-phase micro-extraction and GC / MS analysis, 31 species chemical constituents were identified, The main components were 1R-α-pinene, α-pinene, myrcene, limonene, caryophyllene, etc.; the inhibiting effect about the cedar on bacteria, fungi, actinomycetes were studied ,the results show that the cedar has a stronge ability to remove micro-organisms and the ability changes with the seasons, this difference was related to the volatile organic compounds.
