Composition of Volatile Oil ofSyzygium aromaticumBuds

Abstract A steam-distilled essential oil obtained from buds of Syzygium aromaticum was characterized by a high percentage of oxygenated monoterpenes (53.2%) dominated by myrtenone (49.1%) and pulegone (4.1%). Oil contained three sesquiterpenes (about 10%), which consisted of β-caryophyllene (8.7%), α-humulene (1.1%) and caryophyllene oxide (1%). The major non- terpenic component is eugenol (27.1%) followed by palmitic acid (4.3%), and formic acid (1.6%).
