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.

The herbal material of <em>Coriandrum sativum </em>is the fruit. Fresh herb is also used as an aromatic spice. The aim of the present study was to evaluate the content and chemical composition of coriander herb obtained at different plant growth stages. Coriander plants were grown in a glasshouse, the herb was harvested at the initial stage of flowering and from regrowing shoots. Essential oil extraction from the herb was performed by the hydrodistillation method, whereas the assessment of the chemical composition – using GC-MS method. The examined material contained 0.17–0.29 ml × 100g<sup>-1</sup> of essential oil, depending on the stage of plant development when the harvest was done. 61 (generative phase) and 65 (vegetative phase) compounds were found in the examined coriander oil. The essential oil from the coriander herb contained the highest amount of aliphatic aldehydes, among which was decanal, <em>E</em>-2-dodecanol and <em>E</em>-2-decenol had the highest percentages. The contents of most aliphatic aldehydes decreased with each subsequent harvest of the herb. In addition to the above-mentioned aliphatic aldehydes, the presence of linalool, phytol, and oleic acid was found in the essential oil extracted from the coriander herb.

Abstract BackgroundThe present study investigates the effect of growth stage (vegetative, flowering and seed ripening) and altitude (1500, 2000 and 2500 m above sea level) on the content and chemical composition of S. limbata essential oil which belongs to Lamiaceae family.ResultsAccording to the oil analysis, 28 components representing 96.5% to 99.7% of the total volatile oil composition were characterized. The main compounds of S. limbata oils were α-pinene (14.7-38.7%), β-pinene (12.5-26.2%), allo-aromadendrene (9.2-21.7%), germacrene D (4.2-8.3%), bicyclogermacrene (6.5-14.5 %), and spathulenol (7.5-25.4 %).DiscussionThe obtained results showed that the content and constituents of S. limbata essential oil strongly depend on the growth stage and altitude. Our findings revealed that the vegetative stage at 1500 m is the optimal harvest time to obtain the highest content of oil yield. Results of the current study helps to find the optimum situation to gain the highest content of S. limbata essential oil but more researches are needed.

Oil Composition

One of the most important families of Iranian flora is Apiaceae (Umbelliferae). Most of the species of this family are aromatic plants and rich in essential oils with diverse structures. In the present review, the essential oil composition of 63 genera comprising 141 Apiaceae (66.4% native 33.6% endemic) is summarized.
