Variation of Essential Oil Composition of Eucalyptus Camaldulensis (Myrtaceae) From The Montengero Coastline

Abstract

In the current study the essential oil obtained from the leaves of Eucalyptus camaldulensis plants collected from five localities of the Montenegro coastline was analyzed. The oil yield varied from 0.63 % (Kotor) up to 1.59% (Tivat). The chemical composition of the leaf essential oil was analyzed using GC-MS technique. Monoterpene hydrocarbons were a major class of compounds. Among them, dominant compounds were p-cymene (17.38-28.60%), -phellandrene (12.35-14.47%) and -pinene (0.94-11.48%). The second largest group was oxygenated monoterpenes with cryptone (4.97-7.25) and terpinene- 4-ol (2.75-4.21%) as predominant. Besides high content of sesquiterpene alcohol spathulenol (7.83-14.15%) was found. According to the results obtained E. camaldulensis from Montenegro can be classified in the chemotype with low 1,8-cineole and high p-cymene and cryptone ratio.
