N. Tabanca et al., Composition and antimicrobial activity of the essential oils of Micromeriacristata subsp phrygia and the enantiomeric distribution of borneol, J AGR FOOD, 49(9), 2001, pp. 4300-4303
Water-distilled essential oils from herbal parts of Micromeria cristata (Ha
mpe) Griseb. subsp. phr a P. H. Davis (Endemic) (Lamiaceae) collected from
three different localities were analyzed by GCMS. The major component chara
cterized in the three oils was borneol (27-39%). Other main components were
determined as camphor (9-15%), caryophyllene oxide (4-6%), and trans-verbe
nol (4-6%) in the oils. Enantiomeric distributions of borneol and camphor i
n the oils were determined on a fused silica Lipodex-E capillary column usi
ng a multidimensional GC-MS system. The three essential oils and both enant
iomers of borneol have been evaluated for their antimicrobial activity. The
y showed inhibitory effects on Gr (-) and Gr (+) pathogenic microorganisms.
