Essential oils constitute a heterogeneous collection of chemical compounds. Their main characteristics are that they all synthesized by plants and are volatile and mostly soluble in ethanol. They have traditionally been obtained from plants and they have been widely used for insecticidal, medicinal and cosmetic purposes. Essential oils contains about 20–60 components at quite different concentrations and they are characterized by two or three major components at fairly high concentrations. Lately, the essential oils and various extracts of plants have gained special interest as sources of natural antimicrobial and antioxidant agents because of the resistance to antibiotics that some microorganisms have acquired and the possible toxicities of the synthetic antioxidants. Spices consumed daily in different types of food to improve flavors, since ancient times, are well known for their antioxidant and antimicrobial properties. During recent decades, numerous numbers of plants have been monitored for their possible role as repellents and insecticides. In this review, the chemical composition profile of some important medicinal plants was evaluated, then antimicrobial properties of a number of essential oils was compared. Antioxidant activity of some essential oils was also considered. Finally, essential oil repellent properties an an important characteristics was evaluated. Further investigation for available data related to the other biological properties of medicinal plants essential oil is recommended.DOI: http://dx.doi.org/10.3126/ijls.v9i2.12043 International Journal of Life Sciences 9 (2) : 2015; 9-13

In recent years, the development of new bio-based products for biocontrol has been gaining importance as it contributes to reducing the use of synthetic herbicides in agriculture. Conventional herbicides (i.e., the ones with synthetic molecules) can lead to adverse effects such as human diseases (cancers, neurodegenerative diseases, reproductive perturbations, etc.) but also to disturbing the environment because of their drift in the air, transport throughout aquatic systems and persistence across different environments. The use of natural molecules seems to be a very good alternative for maintaining productive agriculture but without the negative side effects of synthetic herbicides. In this context, essential oils and their components are increasingly studied in order to produce several categories of biopesticides thanks to their well-known biocidal activities. However, these molecules can also be potentially hazardous to humans and the environment. This article reviews the state of the literature and regulations with regard to the potential risks related to the use of essential oils as bioherbicides in agricultural and horticultural applications.

Background: Stevia serrata Cav. (Asteraceae), widely found in Guatemala, is used to treat gastrointestinal problems. The aim of this study was to demonstrate the antinociceptive and anti-inflammatory effects of the essential oil (EO) and the mechanism of action. Methods: EO was tested in chemical (capsaicin- and glutamate-induced licking response) or thermal (hot plate) models of nociception at 10, 30 or 100 mg/kg doses. The mechanism of action was evaluated using two receptor antagonists (naloxone, atropine) and an enzyme inhibitor (L-NAME). The anti-hyperalgesic effect was evaluated using carrageenan-induced nociception and evaluated in the hot plate. Results: All three doses of EO reduced licking response induced by glutamate, and higher doses reduced capsaicin-induced licking. EO also increased area under the curve, similar to the morphine-treated group. The antinociceptive effect induced by EO was reversed by pretreatment of mice with naloxone (1 mg/kg, ip), atropine (1 mg/kg, ip) or L-NAME (3 mg/kg, ip). EO also demonstrated an anti-hyperalgesic effect. The 100 mg/kg dose increased the latency time, even at 1 h after oral administration and this effect has been maintained until the 96th hour, post-administration. Conclusions: Our data suggest that essential oil of S. serrata presents an antinociceptive effect mediated, at least in part, through activation of opioid, cholinergic and nitrergic pathways.

Background: Traditionally, The Algerian medicinal plant Elaeosilenum thapsioides have been used for many diseases. Objective: The present research work is aimed to explore the chemical and biological characterization of essential oil of, Elaeoselinum thapsioides (Desf.) Maire. Methods : The essential oils were obtained by hydrodistillation of different Elaeosilenum thapsioides (Apiaceae) aerial parts samples collected from two different regions (Mahouane and Megres) Setif, Eastern Algeria. The chemical characterization of the obtained essential oils was investigated in the present work for the first time by GC and GC-MS. Besides, they were evaluated for their in-vitro acetylcholinesterase (AChE) inhibitory activity whose enzyme hyperactivity is involved in Alzheimer’s disease. Using Ellman’s spectrophotometric method, additionally, their in-vitro antimicrobial activity was assessed by the disc diffusion method. Both activities were performed at various oil concentrations. Results: The GC/MS analysis of the aerial parts (leaves, stems, flowers, and seeds) essential oils of E. thapsioides revealed the presence of dominant compounds and others in small quantities, identifying 47 chemical molecules. Monoterpene hydrocarbons were the main components, ranging from 72.78 % to 99.13 %. Oxygenated monoterpenes and oxygenated sesquiterpenes ranged between (1.37 % -17.25 %) and (0.12 % -3.53 %) in leaves and stem essential oils. Sesquiterpene hydrocarbons were present in small to large quantities in the essential oils of both populations, with contents ranging from 0.69 % to 13.44 %. For the Isothiocyanates, their presence was recorded in leaves and stem essential oils from Mahouane and Merges with 9.73 % and 3.72 %, consecutively. Indeed, the essential oil of the Mahouane stem showed the highest AChE inhibitory activity among all the tested essential oils. Whereas the highest antibacterial activity was shown by the essential oil obtained from Megres leaves against Bacillus cereus ATCC 11778. Conclusion: The oils exhibited a moderate inhibitory activity in both activities.

The intention of this study was to compare the different parts of Tunisian Ferula communis via their fatty acids, essential oils and phenolic compounds. Results showed that the lipid fraction of fruits and leaves was characterized by the predominance of oleic acid. Erucic and linoleic acids were the most abundant in stems while linoleic and palmitic acids in flowers. F. communis essential oils were defined by four chemotypes, namely isoshyobunone/6-tert-butyl-4-methylcoumarin in stems; α-eudesmol/ caryophyllene oxide in leaves; caryophyllene/myrcene in flowers and α-gurjunene/hexadecanoic acid in fruits. So, oxygenated sesquiterpenes and sesquiterpene hydrocarbons represented the major classes of stem essential oil. Monoterpene hydrocarbons were the predominant classes of leaves and flowers. Fruit essential oil was predominated by sesquiterpene hydrocarbons. Resorcinol and ferulic acid were the main phenolic compounds in flowers but chlorogenic and ferulic acides in leaves. Stems were rich in ferulic acid and quercetin while leaves in coumarin and tannic acid. Besides to the high variability among F. communis parts, this plant contained high amounts of bioactive compounds with various health benefits attributed to their antioxidant potential.

AbstractSome forest trees have been polyploidized to improve their traits and to supply new germplasms for breeding programs. As trees have a long juvenile stage, the early characterization of the chromosome set doubling effects is crucial for previous selection. Thus, we aimed to characterize the chemical variability of essential oils from diploid and autotetraploid germplasms (autotetraploid A and B) of Eucalyptus benthamii, as well as to evaluate their larvicidal and allelopathic effects. Autotetraploid A showed a higher essential oil yield than diploid and autotetraploid B, which did not differ quantitatively. Aromadendrene, viridiflorol and α-pinene were the major compounds in the diploid essential oil. In contrast, compounds were present in autotetraploids, such as 1,8-cineole, limonene, α-terpineol, and α-terpinyl-acetate. Essential oils from the diploid at 50–200 ppm were twice as larvicidal than those from autotetraploids against Aedes aegypti larvae. Considering the phytotoxicity bioassays using Lactuca sativa, essential oils from both ploidy levels affected root growth. Moreover, the essential oils inhibited shoot growth at all concentrations tested (187.5; 375; 750; 1500; and 3000 ppm). Autotetraploid A and B had the same effect on shoot growth as glyphosate. The essential oils had no cytogenotoxic effect on root meristematic cells of L. sativa, whereas phytotoxic potential was identified mainly in shoot growth. This work demonstrated a dramatic change in secondary metabolism (terpene composition) related to an increase in the ploidy level in Eucalyptus germplasms. In addition, we report the novelty of the chemical composition of essential oils among germplasms and their potential use as larvicidal and post-emergence weed control agents.
