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

Abstract

Oils produced from pre-fowering and fowering 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 identifed. Important hydrocarbons were a-pinene (7.2–10.6%) with β-pinene (4.9–7.0%) as monoterpenes and β-caryophyllene (2.5–4.2%) with α-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.
