Essential oil analysis of Nepeta argolica Bory & Chaub. subsp. argolica (Lamiaceae) growing wild in Greece

The chemical composition of the essential oils obtained from the aerial parts of two different populations of Nepeta argolica Bory & Chaub. ssp. argolica (Lamiaceae) was examined by GC and GC–MS. Their components were mainly represented by oxygenated sesquiterpenes. Copyright

A comparative study on the needle volatile constituents of three Abies species grown in South Balkans.

Abstract The phylogenetic relationships of the three Abiesspecies grown in Balkan Peninsula were investigated through their volatile secondary metabolites. The leaf oil of a statistically representative sample of sympatric Abies alba, A. cephalonica and A. borisii-regis trees was obtained and analyzed by means of GC and GC/MS. Forty components were identified and quantified on the basis of their retention indices, their mass spectra characteristics and relative peak areas. The majority of the investigated oils were found to consist of monoterpenes. The major constituents were the same in all studied species but their content varied significantly, thus allowing the assignment of characteristic chemical profiles based on their contribution rank. The variation of the oil constituents and their possible taxonomic significance is discussed.

Chemical composition of the essential oil of Achillea umbellata growing in Greece

The essential oil of the aerial parts of the endemic Achillea umbellata (Compositae) was obtained by hydrodistillation and analysed by gas chromatography (GC) and gas chromatography coupled to mass spectrometry (GC-MS). Sixty-six constituents were identified. The major constituents of the oil were β-thujone (62.8%) and camphor (8.7%).

An Interpopulation Study of the Essential Oils of Various Parts of Crithmum maritimum L. Growing in Amorgos Island, Greece

Abstract The composition of the essential oil obtained from different parts of Crithmum muritimum L., growing in Amorgos island (Greece) and their interpopulation variability were investigated by GC and GUMS. The yield of the essential oil from various parts of the plants in the examined populations, varied from 0.08-0.99%. Monoterpenes constituted the more important portion of the oil while a few sesquiterpene hydrocarbons were detected in small amounts. The major compounds detected in all cases were p-cyrnene (0.8-15.8%), methyl thymol (4.4-41.0%), terpinen-4-01 (3.9-16.0%), sabinene (1.1-24.7%), β-phellandrene (0-10.3%), γ-terpinene (6.9-28.6%), or even dillapiole (0-48.8%) in one case. The results obtained from GUMS analysis of the oils were subjected to multivariate analysis (cluster analysis).

Composition of the Essential Oil of Spontaneous Rosmarinus officinalis from Greece and Antifungal Activity Against Phytopathogenic Fungi

Abstract The chemical composition of the essential oil of spontaneous Rosmarinus officinalis from Greece was analyzed by GC and GC/MS and tested for its antifungal activity against five phytopathogenic fungi (Sclerotinia sclerotiorum, Phytophthora nicotianae, Sclerotium cepivorum, Fusarium oxysporum f. sp. dianthi and Fusarium proliferatum). Thirty-seven components compounds representing 97.3% of the total oil were identified. The major constituents were α-pinene (24.1%), camphor (14.9%), 1,8-cineole (9.3%), camphene (8.9%), α-terpineol (8.8%) and borneol (8.0%). The most sensitive fungus was Ph. nicotianae, followed by S. sclerotiorum, S. cepivorum, F. proliferatum and F. oxysporum f. sp. dianthi.

Essential Oil Composition of the Endemic Species Thamnosciadium junceum (Sm.) Hartvig

Abstract The essential oil of the aerial parts of the endemic Greek species Thamnosciadium junceum was analyzed by GC and GC/MS. Seventy-one compounds representing 98.9% of the total oil were identifed. The major constituents were limonene (33.5%), (E)-isomyristicin (15.4%) and terpinolene (9.0%).

Chemical Composition of Alkanna orientalis from Greece

Abstract The chemical composition of fresh aerial parts oil of Alkanna orientalis (L.) Boiss. was examined by GC and GC/MS. Twenty-eight components were identified representing 98.1% of the total oil. The main components were β-eudesmol (36.9%), α-eudesmol (16.3%) and γ-eudesmol (14.1%).

Volatile constituents of Erica manipuliflora Salisb. from Greece.

Abstract The essential oil of the aerial parts of Erica manipuliflora Salisb. from two Greek regions were investigated by GC/MS. Thirty four and fifty one components were identified in the two oils representing 88.3% and 92.0% respectively.
