Abstract The chemical variations of the essential oil from the aerial parts of Laurus nobilis L. (Lauraceae) have been studied. Plant material has been harvested at each phenological status (vegetative, before anthesis, full flowering and seed-bearing). The oils were obtained by hydrodistillation of the air-dried samples. Analysis by GC and GC-MS of the essential oils has allowed to identify 39 compounds. The main compounds were 1,8-cineole, trans-sabinene hydrate, α-terpinyl acetate, methyl eugenol, sabinene, eugenol and α-pinene.

Abstract- The essential oil composition from the aerial parts of Ormenis africana (Asteraceae), an endemic species from Morocco, has been investigated by GC/MS. A total of 31 compounds were identified, representing 77%. After fractionation by column chromatography, the main compound was isolated and its structure elucidated by NMR spectroscopy. The essential oil was dominated by oxygenated compounds with spathulenol (45.8%) followed by camphor (7.1%), -cadinol (5.9%) and -bisabolol (5.9%) as the main compounds. This oil can be classified as spathulenol-type according to its spathulenol content. In vitro the antibacterial activity of the whole essential oil against three Gram positive (Bacillus cereus, Enterococcus faecalis, Streptococcus C) bacteria and three Gram negative (Proteus vulgaris, Escherichia coli, Pseudomonas aeroginosa) bacteria, showed significant results. Keywords: Asteraceae, Ormenis africana, Essential oil, Spathulenol, Antibacterial activity.

Thymus Serpyllum

The hydrodistilled essential oil of aerial parts of Thymus serpyllum L. (Lamiaceae), cultivated in the Kumaon region of western Himalaya was analyzed by GC and GCMS. Twenty-nine compounds, representing 91.8% of the oil, were identified. The major components were thymol (58.8%), p-cymene (5.7%), thymol methyl ether (4.0%), borneol (3.8%), sabinene (3.4%), γ-terpinene (3.4%) and carvacrol methyl ether (3.2%).

Essential Oil Yield

The essential oil of aerial parts of Helichrysum conglobatum (Viv.) Steudel. (Asteraceae) from Cyprus was analyzed by GC and GC-MS. The essential oil yield was 0.01, v/w. Forty five compounds were identified in the oil comprising 96.1% of the total. The essential oil was mainly composed of sesquiterpene type compounds and oxygenated sesquiterpene derivatives. The main components of the oil were β-caryophyllene (14.6%), γ-curcumene (14.1%), hexadecanoic acid (13.5%), tetradecanoic acid (7.5%), rosifoliol (5.4%) and δ-cadinene (5.3%). This is the first report on the essential oil composition of H. conglobatum from Cyprus.

Total Oil

Variations in the essential oil composition of aerial parts of pineapple weed (Chamomilla suaveolens (Pursh) Rydb.) growing wild in Estonia, were determined using GC/FID and GC/MS. Forty-four components were identified, representing over 90% of the total oil. Nine compounds have not been mentioned in the literature before. The principal biologically active compounds in C. suaveolens oils were (Z)-en-yne-dicycloether (17.0 – 40.7%), (E)-β-farnesene (19.5– 32.2%), geranyl isovaleriate (8.4 –18.4%), palmitic acid (0.3 – 9.4%) and myrcene (1.1 – 7.9%). The investigation seems to approve the benefit of using aerial parts of pineapple weed as the substitute for flowers.
