Περίληψη:
The chemical compositions of the essential oils obtained from the aerial parts of Helichrysum kraussii and H. rugulosum were analysed by GC and GC-MS. From the 39 identified constituents, representing 85.1% and 92.9% of the two oils, respectively, β-caryophyllene (30.7%, 12.6%), α-pinene (12.1%,-), β-caryophyllene oxide (-, 8.8%), cis-α-bisabolene (-, 22.7%), β-bisabolene (-, 4.7%) and α-humulene (9.8%, -) were found to be the main components. Furthermore, the oils were tested against six Gram-positive or - negative bacteria and three pathogenic fungi. It was found that oils from both plants, and especially that of H. rugulosum, exhibited interesting antibacterial activity. Copyright © 2002 John Wiley & Sons, Ltd.
