Abstract

The essential oils from seeds of Chimonanthus praeco were analyzed by GC/MS,thirty-one compounds in the oils were identified.There are 14 compounds' relative mass is more than 1.0%,9 compounds' relative mass is more than 2.0%;4 compounds' relative mass is more than 8.0% and 12.0% respectively,and only a compound's relative mass is more than 21.0%.The results showed that oleic acid(21.70%),1,-methyl-calycanthine(12.74%),linoleic acid(12.62%),hexadecanoic acid(8.69%),calycanthidine(8.15%),caryophyllene(3.90%),linolenic acid(3.88%),phthalic acid diisobutyl ester(2.30%) and stearic acid(2.17%) were the major components of the essential oils,their total up is 76.15%.
