Chemical Composition of the Essential Oils of Pistacia atlantica Desf.

Abstract The chemical composition of the three essential oils obtained by hydrodistillation of the resin, leaves and fruits of Pistacia atlantica Desf. (Anacardiaceae) was studied by GC and GC/MS. Monoterpene hydrocarbons constituted the main chemical group in the resin oil, with α-pinene (42.9%) and β-pinene (13.2%) as the major components. Oil of the fruits contained high amounts of oxygenated monoterpenes, with bornyl acetate (21.5%) as the major component, while oxygenated monoterpenes and sesquiterpenes were found to predominate in the oil of leaves among which terpinen-4-ol (21.7%) and elemol (20.0%) were the most abundant components.

Chemical composition of the essential oils of leaves and wood of Tetraclinis articulata (Vahl) masters

Abstract The essential oils from leaves and wood of Tetraclinis articulata (Vahl) Masters from Morocco were analyzed by GC and GC/MS. The main constituents of the leaves were bornyl acetate (16.5%), camphor (19.1%) and borneol (9.6%), while cedrol (28.2%) and 1,7-di-epi-cedrol (17.9%) were the major components found in the wood.

Chemical Composition of the Essential Oil from the Leaves of Juniperus phoenicea L. from North Africa

Abstract The chemical study of the essential oil extracted from leaves of Juniperus phoenicea growing in Morocco has been carried out. The main components of J. phoenicea oil were the monoterpene hydrocarbons α-pinene (45.5%) and ω-3-carene (13.0%). Our results show a number of differences in composition with respect to a previous study of the leaf oils of J. phoenicea (Greece and Spain).

Composition and Antimicrobial Activity of Essential Oil of Anthemis tenuisecta Ball

Abstract The Chemical composition of the essential oil of Anthemis tenuisecta Ball. (Anthemideae) was analyzed by gas Chromatography-mass spectrometry (GC-MS). Forty eight components accounting for 89.5 % of the oil were identified, being camphor (17.5 %), 6-methyl-5-hepten-2-one (17.1 %), borneol (11.5 %), sesquicineole (11%) and camphene (5.7 %) the main compounds. In the antibacterial diffusion assay, the oil showed activity against Gram-positive bacteria.

Antibacterial diterpenoids from Cedrus atlantica

Four diterpene alcohols were isolated from the neutral hexane extract of the cones of Cedrus atlantica, and their structures were confirmed after comparing their spectral data with literature values. These products exhibited significant antibacterial activity against gram (±) bacteria.

Composition and Antibacterial Activity of Essential Oils of Cladanthus arabicus Cass. (Asteraceae)

Abstract The chemical composition of the essential oils of the aerial parts (stems and leaves: sample A) and flowers (sample B) of Cladanthus arabicus Cass., were analysed by GC-MS. Monoterpenes hydrocarbons constituted the main chemical group in both essential oils, with Sabinene, β-pinene, α-pinene, myrcene, α-phellandrene and p-cymene as the main compounds. Sample A was tested for its antimicrobial activity against six Gram positive and negative bacteria. Results showed that the oil exhibited a significant antibacterial activity.
