Samples of essential oil from Tamarix ramosissima plant growing in the Astrakhan region were obtained by steam distillation and the dependence of its yield on the vegetative period of the plant was studied. The duration of the process of steam distillation was established experimentally on the basis of a study of the dynamics of the change in the yield of essential oil in time. The yield of essential oil was determined in % by weight of absolutely dry raw material. The largest yield of essential oil was obtained from plants in the flowering phase (0,23–0,3%). By method of gas-liquid chromatography carried out a quantitative analysis of the main components of essential oil Tamarix ramosissima. The quantitative content of essential oil components was calculated from the areas of gas chromatography peaks without the use of correction factors. Qualitative analysis was carried out by comparing the linear retention indices. It was found that the composition of the essential oil of Tamarix is very specific. It includes hydrocarbons (9,51%), alcohols (3,46%), aldehydes (2,55%), monoterpene hydrocarbons (5,4%), oxygenated terpenes (23,06%), sesquiterpene hydrocarbons (1,48%), oxygenated diterpenoids (3,37%), and a significant amount of fatty acids and their esters (45,43%). The main components of the essential oil are tetrahydrogeranilacetone (21,35%), nonane (12,63%), decanoic (9,82%) acids and dihydroactin diolide (5,40%).

The chemical composition of Prangos odontalgica (Pall.) Herrnst. et. Heyn essential oil, which grows wild in the Astrakhan region, has not been practically studied, unlike other species of the genus Prangos, growing in Iran, Turkey and Uzbekistan. To obtain the essential oil, all parts of the plant (roots, stems, flowers, leaves, fruits) are used, as well as various methods of isolation (hydrodistillation, supercritical fluid extraction, solid-phase microextraction, and others). Essential oil from the fruit of Prangos odontalgica we obtained by the method of hydrodistillation. The duration of the hydrodistillation process, established experimentally on the basis of a study of the dynamics of change in the yield of essential oil over time, was 3 hours. The yield of essential oil in mass% by volume in terms of absolutely dry raw materials according to the results of a threefold determination is 0.07 ± 0.01%. The method of gas-liquid chromatography carried out a quantitative analysis of the main components of the essential oil Prangos odontalgica. The quantitative content of the components of the essential oil was calculated by the areas of gas chromatographic peaks without the use of correction factors. Qualitative analysis was performed by comparing linear retention indices. In the Prangos odontalgica essential oil, 38 substances were identified (88.4%). It contains sesquiterpenes (31.48%), terpenoids (19.2%), hydrocarbons (15.39%), carboxylic acids and their esters (10.86%), alcohols, phenols (8.84%). Among sesquiterpenes, the predominant components are γ-elemen (9.84%), bisabolol (9.41%), and among terpenoids – trans-nerolidol (3.90%) and linalyl isobutyrate (3.41%).

Plants of Helichrysum genus belong to Asteraceae family and abound with species. The’re two species of plants of Helichrysum genus in the Astrakhan region – Helichrysum arenarium Moench and Hеlichrisum nogaicum Zvelev that was discovered later and isn’t studied well enough yet. Helichrysum arenarium is a well-known medical plant widely used in both academic and traditional medicine and included into the State Pharmacopoeia. Inflorescences of Helichrysum arenarium produce cholagogic, hemostatic, detoxicating, laxative, anti-inflammatory and diuretic effects, which is due to content of flavonoids, terpenoids and other components. This works shows results of studies of chemical composition of extracted essential oils of Hеlichrisum nogaicum and Helichrysum arenarium growing in the Astrakhan Region. Samples of essential oils of plants under studies have been obtained by steam distillation. Optimal steam distillation process duration has been determined by experiment taking studies of dynamics of essential oil yield change through time as a ground. Quantitative analysis of main components of Helichrysum arenarium and Hеlichrisum nogaicum essential oils has been carried out by gas-liquid chromatography. It has been identified that Helichrysum arenarium essential oil contains 21 substances. Its main components are camphor (14.59%) and carboxylic acids (37.02%), and 1,8-cineole (5.97%). The main components of the oil Helichrisum nogaicum are camphor (38.33%), borneol (14.21%), cineol-1.8 (11.37%) and terpene-4-ol (5.18%), sesquiterpene compounds (6.28%), and the content of carboxylic acids is insignificant and amounts to 6.58%.

The volatile fraction composition of commercially produced sweet and bitter orange oil from fruit peels was studied using GC-MS. More than fifty components were identified in the oils using their mass spectra and linear retention indices. The monoterpene limonene was the most abundant component even though not in a quantity expected for a fresh orange essential oil. Aldehydes, followed by alcohols and esters, were the main components in the oxygenated fraction. Aldehydes were the major oxygenated components in the sweet orange oil, whereas alcohols and esters were present in higher amounts in the bitter orange oil. Among them, nonanal, decanal and linalool are the most important components for the flavour of sweet orange oil and carvon is the most important ketone for the flavour of bitter orange oil in combination with the other components. The amount of carvon gives a good indication about the freshness of the oil and the quantities of α-pinene and β-pinene, sabinene and myrcene give an indication about the natural or artificially changed composition of the essential oils.

Patchouli essential oil can be obtained from fresh, dried and fermented plant material. It is a highly valuable product in the fragrance industry and its quality changes depending upon raw material age and oil storage. In this work, patchouli essential oils derived from different treatments have been subjected to GC-FID quantitative analysis using an internal standard (ISTD) method with response factors (RF). Samples were obtained from i) fresh plants; ii) hydrodistillation of one year mature and fermented plants; iii) hydrodistillation of one year mature plants; iv) commercial products from Indonesia and Malaysia. Linear Retention Indices (LRI) for both polar and non-polar GC-MS analyses were also measured as a tool for qualitative analysis towards a homologous series of C7-C30 n-alkanes. The results obtained confirmed that, in all samples, patchouli alcohol was the main volatile constituent, with higher amount in lab-scale produced oils, compared with commercial samples. Other major compounds, in lab oils and commercial samples respectively, were: δ-guaiene, α-guaiene, pogostol, seychellene and α-patchoulene. Another 36 compounds were also found.

Phoebe Bournei

Abstract Background: Phoebe bournei is a potential medicinal plant whose essential oil (EO) from leaves has potential inhibitory activities against some bacterium, tumor, and has a certain potential for hypoglycemic activity. Fertilization is a common and effective method to increase plant biomass, which can increase the raw material of essential oil, but has a certain impact on the composition and biological activity of plant essential oil. Results: The main components are sesquiterpenes in the essential oils from leaves and twigs. The yield of the essential oils and the content of their main components can be modulated by compost and compound fertilizer, to different degrees, and minor differences were registered among the categories of the components in essential oils. However, changes were strongly mirrored in some main components of essential oils. The content of the primary (+) - calarene in the leaf EO were strongly increased by compost, but the opposite happened by compound fertilizer. On the contrary, the effect of compound fertilizer was more significant on the main components of twig essential oil than compost. The transcriptome sequencing results of P. bournei showed that the total number of DEGs in twigs and leaves treated with compost were significantly more than that with compound fertilizer. No change was found in the expression of genes regulating principal components. However, the expression of several key genes regulating the upstream substrates for the synthesis of the sesquiterpenes was significantly changed: the expression of two key speed limiting enzymes genes (DXS and HMGR) and two important branch-point enzyme genes (FPPS and GGPPS) was significantly down regulated, while the expression of gene (HMGS) was significantly up-regulated.Conclusion: The expression levels of genes (DXS2, HMGR, FPPS and GGPPS) were significantly down regulated in leaves treated with compost, resulting in the changes of the yield and main components of the leaf essential oil. The effect of compost was more significant on the synthesis of the essential oil from P. bournei leaves than that of compound fertilizer.

The present study reports the chemical composition on the essential oil obtained from fresh roots, stems, inflorescences and fruits of Chaerophyllum temulum. In all samples, except the roots, the most dominant components were sesquiterpene hydrocarbons. ( Z)-Falcarinol was the principal constituent of the root essential oils (61.7% at the flowering stage and 62.3% at the fruiting stage). The blossom oil was dominated by ( Z,E)-α-farnesene (23.4%), ( E)-β-farnesene (9.0%) and germacrene D-4-ol (9%), whereas the oil from the fruit had germacrene D-4-ol (27.6%) as its main compound, accompanied by ( Z,E)-α-farnesene (13.4%). Germacrene D was the most abundant component of the stem essential oil (38.4% at the flowering stage and 32.5% at the fruiting stage). The obtained results show that the qualitative composition of the oil depends on the part of the plant which is analyzed, while the quantitative composition of the main components depends on the growing stage of the plant.

Sesquiterpene Hydrocarbons

Plants from the family Myoporaceae, which includes the genus Myoporum, are extremely prized by the Australian Aboriginal people for their medicinal properties. Leaves from a plant, which was subsequently identified as Myoporum montanum, were provided for chemical investigation by representatives of an Aboriginal community from the Northern Tablelands district of northern New South Wales, Australia. Acetone extraction of the leaves provided a complex mixture of compounds including sesquiterpene hydrocarbons and more polar furanosesquiterpenes, which were identified by gas–liquid chromatography and retention indices (sesquiterpene hydrocarbons) and spectrometric techniques (furanosesquiterpenes). The major compounds found in a water extract were studied for their antibacterial activity using a disc diffusion assay and for their cell growth inhibition activity. The acetone extract contained sesquiterpene hydrocarbons (~30 % of the total extract) in which the major compounds were germacrene-D and bicyclogermacrene. In addition, the extract contained five known toxic furanosesquiterpenes: myoporum ketol, (–)-10,11-dehydroisomyodesmone, (+)-10,11-dehydromyodesmone, 10,11-dehydromyoporum ketol, (–)-10,11-dehydromyoporone, and (±)-myoporone. An aqueous extract of the leaves, emulating the medicinal tea used by the Australian Aboriginal community, was found not to contain significant quantities of the sesquiterpene hydrocarbons and the most toxic furanosesquiterpenes. (±)-Myoporone and (–)-10,11-dehydromyoporone remained in the extract as well as a new furanosesquiterpene, 11-hydroxymyoporone. These three compounds were found to have significant antibacterial activity against Staphylococcus epidermidis, Enterococcus faecalis, and Moraxella catarrhalis but low cytotoxicity against a range of cancer cell lines and normal breast cells at 25 µM.

“Yellow moena” (Nectandra longifolia: Lauraceae) is a fragrant leaves-possessing plant commonly used for timber purposes. Nevertheless, so far, there is not available information about its chemical composition. Thus, in the present work is described the components of the essential oil from N. longifolia leaves. The oil was extracted by steam distillation and analyzed by GC/FID  and GC/MS. Twenty eight compounds were therefore identified. The main components were found to be terpinen-4-ol (53.1%), α-terpinene (6.8%), α-phellandrene (4.5%), and β-pinene (3.8%). The chemical composition of essential oil from N. longifolia leaves was consequently in agreement to that of several neotropical Lauraceae plants. In addition, the oil exhibited good antifungal activity against F. oxysporum through dose-dependent mycelial growth inhibition (using amended media and fumigant assays).
