Abstract: In this study,the essential oils in Cunninghamia lanceolata heartwood were water-steam distilled,and their chemical components were analyzed by column chromatography and GC-MS,with their antimicrobial activity tested.The results showed that the essential oils content was 1.794~2.076 (w/w),and 47 peaks were separated.27 compounds,accounted for 99% of crude essential oils,were identified.The essential oils had an obvious antimicrobial activity against Escherichia coli,Staphylococcus aureus,Bacillus sabtills and Salmonella typhi,and cedrol,occupying 76.27% of essential oils,was the major component with antimicrobial activity.

Key words: Cunninghamia lanceolata, Essential oils, Antimicrobial activity, Cedrol
