ABSTRACT When employing GC and GC-MS, constituents of essential oils are most frequently identified by comparing retention indices and mass spectra with those reported in the literature or analytical libraries. While this allows for a rapid analysis, incorrect data can lead to a constituent being repeatedly misidentified. This was demonstrated in this work for 5-oxolinalool (6-hydroxy-2,6-dimethylocta-2,7-dien-4-one), an oxygenated monoterpene that was often erroneously identified as 2-methylnon-2-en-4-one. After encountering an unknown constituent of the essential oil of Sambucus nigra L. (Viburnaceae) flowers, we sought to acquire relevant analytical data on both compounds. Even though their mass spectra were rather similar (with 2-methylnon-2-en-4-one missing the peak at m/z 71), their retention indices were found to be significantly different. It follows that a revision of all prior identifications of 2-methylnon-2-en-4-one as an essential-oil constituent is needed.

ABSTRACT Essential oils (EOs) from Ochna afzelii leaves, stems and roots were extracted and characterised by hydrodistillation and Gas Chromatogragphy-Mass Spectrometry (GC/MS) techniques, respectively. Antioxidant activity was evaluated by 2,2-diphenyl-1-picrylhydrazyl (DPPH*) method while antibacterial activity was determined using agar well diffusion and broth microdilution methods. Leaf, stem, and root oils afforded thirteen, ten and seven compounds, respectively, which were characterized by a high percentage of oxygenated sesquiterpenes and sesquiterpene hydrocarbons. The major compound in O. afzelii leaf and root EOs was β-Atlantol, while the O. afzelii stem EO had (E)-β-ionone as its major compound. The leaf oil displayed highest antioxidant activity (IC50 = 238.14 µL/mL). All the EOs showed antibacterial activities against Escherichia coli, Pseudomonas aeruginosa, Salmonella typhi, and Streptococcus pneumoniae, with the zones of inhibition and MIC values ranging from 12.0–18.0 mm and 2.5–10 µL/mL, respectively. O. afzelii has a mild antioxidant effect, but can be a potential source of natural antibacterial agents.

ABSTRACT Mentha suaveolens Ehrh. is an aromatic herb, traditionally used in the Mediterranean areas. Our objective was to evaluate the effect of inhalation of a commercial essential oil of M. suaveolens on human electroencephalographic (EEG) activity according to gender differences by measuring EEG power spectrum changes in healthy participants. Piperitenone oxide (55.60%) was the most abundant component in the essential oil. Our findings indicated that the inhalation of M. suaveolens essential oil produced different EEG power spectrum changes as well as affected different brain regions between genders. It could be concluded that the inhalation of M. suaveolens essential oil significantly changed the EEG wave activity according to gender and these changes may cause some alterations in the psychophysiological functions of humans. Hence, M. suaveolens essential oil may be utilized in aromatherapy for improving the psychophysiological functions of humans.

ABSTRACT For industries that use aniseed as a raw material, essential oil content and aroma composition are critical factors. Anise fruits were collected from 15 locations to determine these criteria. The essential oil procured by hydrodistillation was analysed by gas chromatography (GC) and gas chromatography–mass spectrometry (GC – MS). The locations were divided into five classes according to the cluster analysis of essential oil components. The most important components that made up the classes were estragole (2.33%), trans–anethole (93.90%), cis-anethole (0.21%), carvone (0.097%), p-anisaldehyde (0.651%), longifolene (1.35%), carvacrol (0.06%) and α-himachalane (0.12%). The rate of essential oil varied between 0.33-3.01% in the locations. Trans–anethole is the main component of the essential oil, while their rates changed according to the populations (90.8–96.6%). Location has a significant (p ≤ 0.05) effect on the essential oil, fruit width, fruit length and a thousand fruit weight; furthermore, it is positively related.

ABSTRACT In this research, aroma profile variation among five population from different parts of Pimpinella tragium and its subspecies were evaluated. According to obtained results, the main chemical component of Pimpinella tragium Vill. in (Khoy) was germacrene D in seed with amount of (51.80%). In Pimpinella tragium Vill. (Ghoshchi), the predominant compound included trans-dictamnol (25.30%) in inflorescence, in addition, in the root part geijerene (26.70%) was the major constituent. Pimpinella tragium Vill. (Tabriz-Ahar), in inflorescence sabinine (36.30%), was introduced as the major compound. In the subspecies of Pimpinella tragium Vill. (Mazandaran), in inflorescence, sabinine (37.10%) was identified as the major constituent as well. In Pimpinella tragium (Alvand-Hamedan) germacrene D (43.5%) was identified in inflorescence as the major compound. In general, it seems that the high value of the essential oil composition within and among Pimpinella tragium and subspecies population could provide useful information for conservation and selection of cross-parents in breeding programs.

ABSTRACT Citrus essential oils, thanks to their pleasant aroma, are certainly the most used ingredients in the formulation of hydroalcoholic fragrances. The non-volatile fraction of Citrus essential oil is composed for 10–20% of coumarins, furocoumarins and polymethoxyflavones. It is well known that furocoumarins induce photosensitization and have potential carcinogenic and mutagenic effects. It follows that furocoumarins levels in cosmetics product are constantly monitored by opinions and regulations issued by the International Fragrance Association. The aim of this research article was to quantify coumarins, furocoumarins and polymethoxyflavones in thirty commercial hydroalcoholic fragrances using supercritical fluid chromatography in combination with triple quadrupole mass spectrometry technique (SFC-QqQ-MS). According to author’s knowledge, this is the first report on the determination of oxygen heterocyclic compounds in hydroalcoholic fragrances by means of SFC-QqQ-MS technique.

ABSTRACT This study aimed at chemical variability of flower essential oils of 10 well-known cultivars of Paeonia × suffruticosa Andr. The essential oil yields ranged as 0.19–0.67% (w/w). The chemical compositions varied with cultivars. ‘Xueying Taohua’ essential oil had predominance of citronellol (56.4%). ‘Guifei Chacui’ essential oil was rich in citronellol (35.9%) and phloroglucinol trimethyl ether (25.3%). ‘Sheng Gejin’ and ‘Yuhou Fengguang’ essential oils were rich in phloroglucinol trimethyl ether (36.5%, 26.8%). ‘Yinhong Qiaodui’ essential oil contained geraniol + nerol (23.9%). Those from the other five cultivars did not present typical chemotypes. Nevertheless several compounds were noted, mainly germacrene D, heptadeca-6,9-diene, (Z)-hex-3-en-1-ol and linalool oxide (furan). ‘Luhe Hong’ essential oil contained the most unique components, including α-cadinol, τ-muurolol and δ-cadinene. Lack of phenylethyl alcohol was noticeable in some essential oil samples as compared with hydrolate extracts investigated previously. Multivariate analyses revealed four distinct clusters from all the essential oil samples.

ABSTRACT In this study, leaf essential oil effects on glutamate toxicity model formed in cortex neurons and LN405 cell cultures were investigated. Antidiabetic activity was evaluated by α-amylase and α-glucosidase inhibitions. MIC was used for antimicrobial activity. Seven groups were examined with MTT. Glutamate 10-5 mM in cortex showed 62% viability whereas oil viability did not increase in a dose-dependent manner and the highest viability rate was observed. There are four types of glandular trichomes in leaf anatomy of walnut. The oil exhibited half as much α-glucosidase inhibitory activity with an IC50 value of 8105 μg/mL, compared to positive control acarbose (IC50 = 4762 μg/mL). MIC of oil was determined to be 625 μg/mL against E. coli, C. albicans, and C. parapsilosis, whereas S. aureus exhibited a MIC of 1250 μg/mL. Major compounds of oil were found as β-pinene (17.6%), α-pinene (11.3%), β-eudesmol (8.6%), and caryophyllene oxide (6.2%).

ABSTRACT Diabetes and obesity are critical health concerns in the world, characterized by weak insulin secretion and activity, leading to increased blood glucose concentrations and an accumulation of excess body fat. There are conventional drugs currently used to treat these conditions, but they provide only short periods of glycemic control, are expensive, and are scarcely available in underdeveloped and developing countries. EOs are complex mixtures of aromatic and volatile compounds obtained from plants. They have numerous pharmacological and industrial applications, including anti-cancer, insecticidal, anti-microbial, anti-obesity, and antidiabetic. This review sought to investigate and organize established in vitro, in vivo, ex vivo, and in silico data, highlighting possible mechanisms of action of essential oils to treat and/or manage diabetes and obesity. The results showed that numerous essential oils from plant parts possess antidiabetic and anti-obesity properties, suggesting that essential oils can be exploited as potential antidiabetic and anti-obesity drugs.

The results showed that numerous essential oils from plant parts possess antidiabetic and anti-obesity properties, suggesting that essential oils can be exploited as potential antidiabetic and anti-obesity drugs.","PeriodicalId":15782,"journal":{"name":"Journal of Essential Oil Research","volume":"28 1","pages":"335 - 371"},"PeriodicalIF":3.0,"publicationDate":"2023-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83601983","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

ABSTRACT In this research, the effect of high-density polyethylene active packaging (HDPAP) bottles containing Coriandrum sativum essential oil (CSEO) on the oxidation stability and sensory attributes of sunflower oil (SFO) during the accelerated storage was investigated. The migration test showed that the CSEO could migrate from the package to SFO. In the accelerated storage procedure at 65°C, the increase in the levels of acid value (AV), peroxide value (PV), p-anisidine value (AnV), thiobarbituric acid reactive substances (TBARS), conjugated dienes (K232) and conjugated trienes (K268) of SFO samples was significantly inhibited after the sunflower oil packaged by the HAPAP containing CSEO at 6000 ppm (p < .05), which showed that the HDPAP bottle containing CSEO could delay the oxidation of SFO. Therefore, the results demonstrated that employment of HDPAP bottles containing CSEO at 6000 ppm could be applied as a good replacement for the direct addition of synthetic antioxidants to the SFO.
