Abstract:

The chemical composition, antimicrobial and antioxidant activities of the essential oil of Artemisia sieversiana,
a traditional medicinal herb in Tibet, China, were investigated. A total of 48 components, representing 95.36% of the total
oil, were identified by gas chromatography-mass spectrometry (GC-MS), with the main constituents being α-bisabolol,
chamazulene, α-phellandrene, palmitic acid and lavandulol. The antimicrobial activities of the oil were evaluated against
five microorganisms, Bacillus subtilis, Escherichia coli, Enterococcus faecalis, Staphylococcus aureus and Crytococcus
neofonman, respectively. The results showed that the oil possessed inhibitory activity against B. subtilis, E. faccalis,
S. aureus and C. neoformans, amon+g which the best inhibition was observed against C. neoforman with a minimum
inhibitory concentration (MIC) of 5.5 μg/mL. The oil revealed a relatively stronger scavenging effect on 1,1-diphenyl-2-
picrylhydrazyl (DPPH), 2,2’-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS+·) and hydroxyl free
radicals in a concentration-dependent way.

Key words: Artemisia sieversiana, essential oil, antioxidant activity, antimicrobial activity
