Aromatic Compounds of Micromeria juliana (L.) Bentham ex Reichenb. from Croatia

Oils produced from pre-flowering and flowering plants of Micromeria juliana L. were investigated by GC/MS. The oils were qualitatively similar but differed quantitatively. After the oil fractionation by LS chromatography and GC/MS analysis, 64 compounds were identified. Important hydrocarbons were aplha-pinene (7.2-10.6%) with beta-pinene (4.9-7.0%) as monoterpenes and beta-caryophyllene (2.5-4.2%) with alpha-gurjunene (2.1-6.4%) as sesquiterpenes. The main oxygenated monoterpenes were linalool (4.7-7.6%) with its furanoid cis- and trans-oxides (3.5-4.6%) and borneol (2.2-3.5%). Other monoterpenes, sesquiterpenes as well as non-terpenoid compounds were present in smaller amount. The results of the present research reveal some differences in the oil composition of M. juliana of Greek origin.
