A Priority

Currently, many herbal substances are used in everyday life products and in many industry such as food, cosmetics and others. Essential oils are mixtures of volatile organic compounds separated from plants or parts of them. They are characterized by an intense fragrance, but they have a diverse composition. Depending on the source, there are one or several dominant components. History acquisition of essential oils dates back to ancient times. Due to the unique fragrance qualities, the oils accompany humanity all the time. More perfect methods of analysis of the composition of essential oils used in cosmetics, food (spices) and aromatherapy, prompts us to consider the safety of their use. In addition to health-promoting substances, oils can also contain many organic compounds with an allergic or even toxic effect. Getting to know the essential oils composition and thorough acquaintance of consumers with possible risks of using essential oils is currently a priority for the producers of essential oils.

Anti Inflammatory

This paper highlights the role of plant volatile organic compounds, found in essential oils, for the treatment of bacteria related inflammation. This report is focused on tea tree oil, particularly its main compound terpinen-4-ol. Analysis of the published literature shows that many essential oils have significant antibacterial, antifungal and anti-inflammatory effects. Some of their major components, such as terpinen-4-ol, act by inhibiting pro-inflammatory cytokine expression while stimulating production of anti-inflammatory cytokines. Such observations may be exploited to encourage biotherapy against mastitis. The use of synthetic antibiotics is being increasingly discouraged because their presence in dairy milk may have potential downstream effects on population health and the agri-food chain. In the context of inflammation and related mammalian responses, understanding the interplay between volatile organic compounds, especially terpinen-4-ol, and cytokines during bacteria related inflammation should clarify their mode of action to control mastitis.

Abstract Background Plants are known to emit diverse volatile organic compounds (VOCs), which may function as signaling substances in plant communication with other organisms. Thuja occidentalis, which is widely cultivated throughout China, releases aromatic VOCs into the air in winter and early spring. The relationship of this cultivated plant with its neighboring plants is necessary for the conservation of biodiversity. Results (−)-α-thujone (60.34 ± 5.58%) was found to be the major component in VOCs from the Shenyang population. The essential oils (EOs) from the Kunming and Shenyang populations included the major components (−)-α-thujone, fenchone, (+)-β-thujone, and (+)-hibaene, identified using GC-MS analyses. (−)-α-thujone and (+)-hibaene were purified and identified by NMR identification. EOs and (−)-α-thujone exhibited valuable phytotoxic activities against seed germination and seedling growth of the plants Taraxacum mongolicum and Arabidopsis thaliana. Moreover, the EOs displayed potent inhibitory activity against pathogenic fungi of maize, including Fusarium graminearum, Curvularia lunata, and Bipolaris maydis, as well as one human fungal pathogen, Candida albicans. Quantitative analyses revealed high concentrations of (−)-α-thujone in the leaves of T. occidentalis individuals from both the Shenyang and Kunming populations. However, (−)-α-thujone (0.18 ± 0.17 μg/g) was only detected in the rhizosphere soil to a distance of 0.5 m from the plant. Conclusions Taken together, our results suggest that the phytotoxic effects and antifungal activities of the EOs and (−)-α-thujone in T. occidentalis certainly increased the adaptability of this plant to the environment. Nevertheless, low concentrations of released (−)-α-thujone indicated that reasonable distance of T. occidentalis with other plant species will impair the effects of allelochemical of T. occidentalis.

The present study aimed at investigating the variation in the chemical composition of emitted volatile organic compounds (VOCs) and essential oils obtained from fresh aerial parts of Inula viscosa (Asteraceae) as affected by growth stage and geographical location zone. VOCs were extracted by solid phase microextraction (SPME) method from whole aerial parts of I. viscosa during the vegetative (spring-August) period, and from fresh leaves, closed pre-flowering buds and fully expanded flowers during the full flowering season (October). The essential oils were extracted by hydrodistillation form fresh organs during the flowering stage. GC/MS analysis of VOCs during the vegetative period revealed sesquiterpene hydrocarbons as main components in the samples collected from the Mediterranean zone (MID-1: 64.72-27.48%, MID-2: 32.09-76.77%). The profile of the samples from the Irano-Turanian zone (IT) was quite different. Myrcenol was the main component in the leaves, pre-flowering buds and fully expanded flowers from all locations (0.61-39.01%). E-nerolidol was the main component in the hydrodistilled oil of all organs from the different locations (73.72-88.66 %). Principle component and cluster analysis revealed that the chemical composition of the essential oils and VOCs belonging to MID-zone were similar and quite different when compared to the composition of the samples belonging to IT-zone. The results indicated the possible use of E-nerolidole as a stable chemotype marker in I. viscosa taxonomy.

Common Juniper

Juniper (Juniperus communis L.) is a common wild or cultivated plant, mainly distributed in the Northern hemisphere. The plant, being one of three natural conifers in the countries of the Baltic Sea region, grows separately or forms stands in Lithuania. It is an evergreen, long-lived shrub or a small tree. Juniper synthesizes various (quantitatively and qualitatively as well) volatile organic compounds depending on the plant origin, organ and developing stage. Essential oils are prepared from different parts of juniper. Juniper berries, the fruit of J. communis, perhaps the most valuable part of the plant, are rich in essential oils. Preparations of them are used traditionally in folk medicine and veterinary as antiseptic, diuretic, anti-helminthic, anti-fungicidal, anti-rheumatic, antibacterial, tonic and anti-inflammatory remedy. This paper reviews the published information concerning data on the chemical composition of essential oils obtained from various plant organs (sprouts, shouts, ripe and unripe berries, leaves, wood and bark) of junipers wild growing (or cultivated) in different localities in Lithuania. Alfa α-pinene is the most common constituent determined in Lithuanian juniper essential oils. This monoperpe hydrocarbon was evaluated as a predominant compound in most of investigated oils, obtained from juniper shoots, sprouts, needles and cones (both unripe and ripe ones).

This study identified the volatile organic compounds in the essential oils that are extracted from Chrysanthemum indicum Linné (C. indicum Linné) and investigated the effects of the inhalation of these compounds. We detected a total of 41 volatile organic compounds, including 32 hydrocarbons, four acids, three alcohols, two ketones, and one aldehyde. In a sniffing test, seven types of volatile organic compounds were identified. Furthermore, the volatile organic compounds in C. indicum Linné that were identified were found to be derived from 1,8-cineole and camphor. After inhalation of the essential oils, the subjects’ systolic blood pressure and heart rate decreased. This indicates that inhalation of the essential oils extracted from C. indicum Linné provides mental and physical relaxation. We examined the changes in electroencephalogram findings that are observed after C. indicum Linné essential oil inhalation. An increase in theta and alpha waves, which usually appear during relaxation, as well as a decrease in beta and gamma waves, which appear during brain activity such as excessive attention, were noted. These results indicate that C. indicum Linné essential oil inhalation helps to reduce blood pressure and may provide mental and physical relaxation.
