Variation of essential oil composition of Eucalyptus camaldulensis (myrtaceae) from the Montengero coastline

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.

The seasonal variation in the chemical composition of the leaf essential oil of Sassafras albidum has been analyzed by GC-MS. Three individual trees were sampled four times during the course of the growing season. The leaf oils were made up of 44 components, with geranial (11%–27%) and neral (10%–18%) dominating. S. albidum showed a general trend of diminishing monoterpenoid concentrations and increasing sesquiterpenoid concentrations during the season.

Sakai & Nagam, E. elatior (Jack) R. M. Sm, and E. brevilabrum (Valeton) R. M. Sm were analyzed by GCMS. The highest oil yield was obtained from E. pyramidosphaera (0.45%), followed by E. elatior (0.38%), E. coccnea (0.30%), E. brevilabrum (0.28%) and E. megalocheilos (0.25%). The major constituents of the essential oils were oxygenated monoterpenes, followed by sesquiterpenes, oxygenated sesquiterpenes, oxygenated diterpenes and diterpenes. The essential oils from E. pyramidosphaera and E. brevilabrum exhibited the best cytotoxicity against MCF 7 (LC50: 7.5±0.5 mg mL−1) and HL 60 (LC50: 5.0 mg mL−1), respectively. Strong inhibition was also observed for the essential oils of E. coccnea and E. megalocheilos against Staphylococcus aureus (MIC: 8.0±0.5 mg mL−1 and 5.0±0.5 mg mL−1) and Streptococcus pyrogenes (MIC: 6.0±0.5 mg mL−1 8.0±0.5 mg mL−1).

The seasonal variation in the chemical composition of the leaf essential oil of Zanthoxylum clava-herculis has been analyzed by GC-MS. Three individual trees were sampled four times during the course of the 2004 growing season. Notable differences were recorded in the essential oil yields from the three trees on the four collection dates; yields were highest in May and lowest in July The leaf essential oils were made up of 25 components, largely menthane monoterpenoids, dominated by limonene (44-73%) and 1,8-cineole (16-43%), with lesser amounts of α-thujene, linalool, γ-terpinene, and α-terpineol. The ratio of oxygenated monoterpenoids to monoterpene hydrocarbons generally increased during the season, largely reflected in the 1,8-cineole/limonene ratio.

The Myrtaceae family has great occurrence in Brazil, mainly in the Atlantic Forest of the South and Southeast regions and presents potential for essential oil production. This work aimed to evaluate the essential oil yield and composition of the species Myrciaria delicatula, Campomanesia xantocarpha, Campomanesia aurea, Calyptranthes clusiifolia, Myrcia splendens, Eugenia osoriana, Myrciaria tenella, Myrceugenia reitzii, Calyptranthes concinna e Myrcia arborensis from a segment of the Atlantic Forest of Parana State. The essential oil extraction was carried out by hydrodistillation of fresh and dried leaves using a Clevenger type apparatus and the chemical composition was analyzed by gas phase chromatography coupled with mass spectrometry (GC/MS). Myrceugenia reitzii showed eesential oil yield superior to other species and the essential oil yield of all species increased after drying. The chemical composition in the samples showed mono and sesquiterpenes , being the sesquiterpenes in higher percentages. The drying conditions affected the essential oil composition of the for the majority of the evaluated species.

The leaf essential oil of Dendropanax gonatopodus from Monteverde, Costa Rica, has been obtained by hydrodistillation and the chemical composition determined by GC-MS. The major components in the leaf oil were ( E)-2-hexenal (16.9%), terpinolene (14.8%), δ-cadinene (13.5%), ( E)-caryophyllene (9.9%), and α-copaene (7.3%). Minor amounts of the aromadendrane sesquiterpenoids aromadendrene (0.3%), alloaromadendrene (0.3%), spathulenol (0.6%) and globulol (0.6%) were also detected. An ab initio investigation of the aromadendrane sesquiterpenoids has been carried out using both density functional (B3LYP/6-31G*) and post Hartree-Fock (MP2/6-31G**) methods. The calculated relative energies of the aromadendranes belie their relative concentrations generally observed in essential oil compositions.

Geographical Variations

The principal aim of this study was to analyze the chemical composition and qualitative and quantitative variability of essential oils obtained from seven naturally grown populations of thePinus peuceGrisebach, Pinaceae in Kosovo. Plant materials were collected from three populations in the Sharri National Park and from four other populations in the Bjeshkët e Nemuna National Park, in Kosovo. Essential oils were obtained by steam distillation and analyzed by GC-FID (Gas Chromatography-Flame Ionization Detection) and GC-MS (Gas Chromatography-Mass Spectrometry). The results showed that the yield of essential oils (v/wdry weight) varied depending on the origin of population and the plant organs and ranged from 0.7 to 3.3%. In total, 51 compounds were identified. The main compounds wereα-pinene (needles: 21.6–34.9%; twigs: 11.0–24%),β-phellandrene (needles: 4.1–27.7; twigs: 29.0–49.8%), andβ-pinene (needles: 10.0–16.1; twigs: 6.9–20.7%). HCA (Hierarchical Cluster Analysis) and PCA (Principal Component Analyses) were used to assess geographical variations in essential oil composition. Statistical analysis showed that the analyzed populations are grouped in three main clusters which seem to reflect microclimatic conditions on the chemical composition of the essential oils.

The fruits of Zanthoxylum leprieurii Guill. & Perr. (Rutaceae) are traditionally used in Africa, particularly in Cameroon, as a spice and in the treatment of sickle cell anaemia. The objective of this study was to investigate the fruit essential oils from different sample locations and during their maturation period by using GC and GC-MS. Except for one sample collected in Aniak which consisted mainly of oxygenated monoterpenes, the volatile composition of Z. leprieurii fruits exhibited relative high amounts of monoterpene hydrocarbons (61.1-90.9%) such as (E)-β-ocimene (13.4-75.2%) and a-pinene (1.1-40.7%). The influence of the maturity stage on the chemical composition of the essential oils has resulted in an increase of oil yield and variations in the content of volatile compounds (a-pinene 13.3-75.6; (E)-β-ocimene 2.9-64.0%). Keywords: Senegal, Zanthoxylum leprieurii fruits, essential oil, chemical variability, stage of maturity and GC-MS.

The leaf essential oils of five species of Beilschmiedia from Monteverde, Costa Rica (Beilschmiedia alloiophylla, B. brenesii, B. costaricensis, B. tilaranensis, and an undescribed Beilschmiedia species “chancho blanco”) have been obtained by hydrodistillation and analyzed by GC-MS in order to discern the differences and similarities between the volatile chemical compositions of these species. The principal constituents of B. alloiophylla leaf oil were germacrene D (18.9%), cis- and trans-β-ocimene (18.8% and 9.3%, respectively), α-pinene (11.8%), and bicyclogermacrene (9.1%). The leaf oil of B. brenesii was composed largely of the sesquiterpenes germacrene D (19.3%), β-caryophyllene (13.4%), α-copaene (9.0%), α-humulene (8.1%), and δ-cadinene (5.8%), and the carbonyl compounds 2-undecanone (12.8%), trans-2-hexenal (8.8%), and 2-tridecanone (3.8%). α-Bisabolol (72.1%) dominated the leaf oil of B. costaricensis, while B. tilaranensis had germacrene D (54.9%), β-caryophyllene (14.8%), and δ-cadinene (5.1%) as major components. Beilschmiedia “chancho blanco” leaf oil was composed largely of β-caryophyllene (16.6%), bicyclogermacrene (14.1%), and α-pinene (12.1%).
