Objective: The aim of this work is to investigate the antibacterial activity of the essential oil obtained from Artemisia lavandulaefolia (A. lavandulaefolia), as the development of microbial resistance to antibiotics make it essential to constantly look for new and active compounds effective against pathogenic bacteria.
Method: The aerial parts of A. lavandulaefolia (1 kg) were subjected to steam distillation for 3 h, using a modified Clevenger type apparatus in order to obtain essential oil. Diethyl ether was the extracting solvent kept at 25?. The essential oil were analyzed by gas chromatography (GC) and gas chromatography／mass spectrometry (GC／MS). The essential oil and the composition were tested for antimicrobial activities against 15 different genera of oral bacteria. Ninety-nine compounds accounting for 94.74% of the oil were identified. The main compounds in the oil were 1,8-cineole (5.63%), yomogi alcohol (4.49%), camphor (4.92%), a-caryophyllene (16.10%), trans-a-famesene (5.09%), a-terpineol (3.91%), borneol (5.27%), cis-chrysanthenol (6.98%), and a-humulene oxide (3.33%). The essential oil and its compounds were tested for antimicrobial activity against 10 different genera of oral bacteria.
Conclusion: The essential oil of A. lavandulaefolia exhibited considerable inhibitory effects against all obligate anaerobic bacteria (MICs, 0.025 - 0.05 ㎎／ml) tested, while their major compounds demonstrated various degrees of growth inhibition
