Abstract: The antibacterial activity of essential oil from heartwood of Chamaecyparis pisifera was evaluated. The test results show that both of essential oil samples from the 5th to 10th year rings in bottom and middle section of C. pisifera tress have significantly inhibitory effects on microbes of Staphylococcus aureus and Escherichia coli. The inhibition diameters of essential oil from middle heartwood of C. pisifera on S. aureus and E. coli reached 14.86 and 14.56 mm, respectively. The essential oil samples from the 5th to 10th year rings in bottom and middle section of C. pisifera tress were analyzed by gas chromatography-mass spectrometry. Results show that these essential oil samples consist of alcohols and terpenoids, but the content of cedrol (26.52%) was the highest in essential oil from middle section of the tree. The cedrol has a great potential of development value as a kind of antibacterial activity compound.
