Fifty-one compounds (90.2% of the total oil) were identified.
The oil was characterized by a high amount of sesquiterpenes (81.1%), with germacrene D (14.8%), viridiflorol (10.6%), caryophyllene oxide (10.5%), and β-caryophyllene (9.4%) being the main components.
The microbial growth inhibitory properties of the oil was determined against Gram-positive bacteria Staphylococcus aureus, St. epidermidis, Micrococcus luteus, Gram-negative bacteria Pseudomonas aeruginosa, Klebsiella pneumoniae, Escherichia coli, and a yeast Candida albicans.
The best inhibitory effect was detected against M. luteus, followed by the effects against St. epidermidis, St. aureus and C. albicans.
Tested Gram-negative bacteria were more resistant than Gram-positive bacteria and C. albicans.DEWEY : 665 ISSN : 1041-2905 En ligne : http://www.jeoronline.com/archive/detail/42#top
