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%), ß-phellandrene (12.35-14.47%) and ß-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

Chemical Composition and in-Vitro Evaluation of the Antimicrobial and Antioxidant Activities of Essential Oils Extracted from Seven Eucalyptus Species

“…EO from E. oleosa stem, immature flowers and the fruit showed 1,8-cineole as principal compound, representing 31.5%, 47.0% and 29.1%, respectively [25]. The results show small variation from a previous study describing a total of 11 components out of which p -cymene (17.4%–28.6%), β-phellandrene (12.3%–14.4%) and β-pinene (0.9%–11.4%) were the main ingredients [26] and great variation from the 1,8-cineole (21.7%), β-pinene (20.5%) and methyl eugenol (6.1%) levels in E. camaldulensis [27]. The study is also comparable to a E. camaldulensis EO analysis reporting 1,8-cineole (45.7%) and p -cymene (17.1%) as major compounds obtained by hydrodistillation and 8,14-cedrane oxide (43.8%) and elemol (6.3%) by supercritical fluid extraction [28].…”

Biological Activities of Essential Oils: From Plant Chemoecology to Traditional Healing Systems

“…f., and Eucalyptus camaldulensis Dehnh. The essential oils extracted from these species are used in traditional medicine to cure various human ailments, such as diarrhea and chronic dysentery, infections of the upper respiratory tract (flu, cold, sinus congestion and fever), and toothache and oral infection [ 148 ]. Moreover, in Traditional Aboriginal Australian Medicines, Eucalyptus essential oil has been used as an antiseptic wash to sterilize sores, cuts, and skin infections [ 149 ].…”

Components of Volatile Fractions from Eucalyptus camaldulensis Leaves from Iraqi–Kurdistan and Their Potent Spasmolytic Effects

“…The leaf essential oils isolated from E. camaldulensis collected in such different countries as Egypt [3], Iran [4][5][6], Kenya [7], Montenegro [8,9], Pakistan [10,11], and Senegal [12], to cite only some of the most recent studies, have been investigated. Moreover, the leaf oil of E. camaldulensis has been reported to have potent antiseptic, antimicrobial properties [9,13,14], and it is commonly used in several countries for treating cough and cold, sore throat and other respiratory diseases [15].…”
