In this overview, the essential oil composition of more than 150 species from about 50 genera of the Apiaceae is reviewed. Essential oil components encountered in Apiaceae proved to be very diverse; they include monoterpenes, sesquiterpenes, rarely diterpenes, phenylpropanoids, phthalides, octanol and octyl esters, trimethylbenzaldehydes and aliphatic aldehydes. In assessing the data one has to keep in mind that the essential oil amount and composition is influenced by many factors, including geographic and genetic variation, physiological aspects and environmental conditions. In some species the occurrence of chemotypes could be demonstrated, but in many cases the data available do not allow the evaluation of infraspecific variability.

Three native species of Leptospermum (L. petersonii, L. Flavescens, L. luehmannii) were grown in an amended podsolic soil under 4 nitrogen (N) levels, 0, 20, 40 and 60 kg Nha, supplied as NH4N03. Plants were harvested after 16 weeks growth, leaves were separated from stems, and essential oil was distilled from leaves by steam distillation. Extracted oils were analysed for their components by gas chromatography. Oil density from L. petersonii was also determined. Growth and oil yield of the 3 Leptospermum species showed no response to N fertilisation. However, the oil composition in L. petersonii and L. flavescens leaves was affected. The greatest response was in the geranial and citronella1 contents in L. petersonii, which peaked in the 40 kg N/ha treatment. This is the first known report of the manipulation of essential oil composition of Australian native plants by N fertilisation. The low optimal level of N fertiliser required for maximum production of valuable oil components indicates that Leptospermum spp. are suitable for infertile soils. The low �-pinene yield of L. luehmannii makes it unsuitable for commercial exploitation.

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.

Lippia citriodora is a member of the genus Lippia. The species is endemic to South America, while it is cultivated in the world for the lemon-like aroma emitted by its leaves. In the present study the  effects of different NaCl as well as 24-epibrassinolide concentrations in the  essential oil composition were investigated. In total, eleven treatments were studied. The major essential oil components in control plants were: Geranial (22.52%), Citral (15.88%) Germacrene D (7.42%), Caryophyllene (7.11%), Benzenamine (6.30%), Spathulenol (6.00%) and Curcumene (5.44%). Significant positive/negative correlations occurred between some components with salt concentration. Paired sample tests showed significant differences between major components of an essential oil with salt as well as with 24-epibrassinolide concentrations.

Talebi SM, Nohooji MG,Yarmohammadi M. 2017. Short Communication: Infraspecific variations in essential oil compositions of Nepeta fissa from Iran. Nusantara Bioscience 9: 318-321. Nepeta fissa C.A. Mey. is a member of Mint family (Lamiaceae) and distributed naturally in different regions of Iran. The aim of this investigation was to provide more information about the influence of environmental conditions on the essential oil composition of two populations, Polor and Dizin, of this species. The dry plant samples were submitted to hydrodistillation for 2.5 h, using a Clevenger-type apparatus. The highest amount of essential oil yields (0.2%) were obtained for Dizin population. Forty-nine compounds, representing 85.9 to 97.80% of the total essential oils, were separated and identified. In Dizin and Polor populations, the essential oils were characterized by the very high percentage of oxygenated monoterpenes (79.1%), oxygenated diterpenes (20.01%) that constituted the predominant classes, respectively. From the analyzed populations, the major compounds in Dizin population were 1, 8-Cineole, 4 a-α, 7-α, 7 a-α-Nepetalactone and 2E, 4E-nonadienal. While, phytol, caryophyllene oxide, E-caryophyllene, and thymol were the core compounds of essential in Polor population. The obtained results showed that environmental conditions are the important factors influencing the yield and also the chemical compositions of essential oils in N. fissa. Knowledge of the essential oil chemical composition in relation to ecological factors is a most prominent quality criterion for its marketing and contributes to its valorization as a functional ingredient in food industry.

Heracleum platytaenium Boiss. (Öğrekotu) is a plant depend on the Apiaceae family, with intense aromatic content and known for its use in traditional medicine. This plant, which is one of the endemic plants of Turkey, is perennial and monocarpic. In this study, the essential oil of the Heracleum platytaenium Boiss., which grows naturally in the northern parts of Bolu province, was obtained by the hidro-distillation method in the Clevenger device and the essential oil components were investigated in the GC-MS device. As a result of the study, the essential oil ratio was determined as 1.4%. Octyl hexanoate (8.76%), 5-Octen-1-ol (7.04%), n-Octyl Caprylate (5.42%), and Beta-Eudesmol (5.01%) were determined as the main components.  In this study, a total of 36 components (81.69%) were detected in the GC-MS device.
