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 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.

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 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.

ABSTRACT Thymus persicus (Lamiaceae) is a range-restricted endemic medicinal and aromatic plant from northwest of Iran. Due to the medicinal importance and over-exploitation of the plant from its natural habitats, conservationand ex situ cultivation of the plant is needed. In the present study, essential oil variability of the plant during its in vitro conservation including in vitro regenerated plant (RP) and acclimated plant (AP) was assessed by GC-FID and GC-MS, and compared with those of growing wild plant (WP). In total, 44, 25 and 25 compounds representing 98.5%, 98.7% and 98.1% were identified in the oils of WP, RP and AP, respectively. The major identified components in the oils were 4,8-β-epoxy-caryophyllene (2.3–10.7%), α-terpineol (9.5–39.2%), linalool (5.7–15.7%) and thymol (2.6–32.8%). In vitro RP with the highest content of thymol had the greatest distance with WP. The AP was also significantly dominated with a large difference in α-terpineol.

ABSTRACT Elettaria cardamomum is known as the ‘Queen of spices’; its leaf essential oil (EO) is least investigated and barely utilized. Here we report the chemical composition of E. cardamomum leaf EOs collected from five locations in the southern Western Ghats in India. EOs of fresh and dry capsules were also analyzed for comparison of their chemical profiles. The major constituents in cardamom leaf EOs were β-pinene (35.6–51.9%) and coronarin E (17.7–34.2%). In fumigant toxicity assays against two stored product pests, lowest LC50 against Tribolium castaneum was recorded in EO of fresh capsules (124.05 µL/L), followed by dry capsules (LC50 128.21 µL/L) and leaves (LC50 148.00 µL/L); LC50s of fresh, dry capsule and leaf EOs against Sitophilus oryzae were 30.24, 35.33 and 89.42 µL/L, respectively. This study demonstrates cardamom leaves as a source of untapped bioactive principles which can be viably utilized for the production of botanical pesticides.

ABSTRACT The consumption of culinary herbs and spices in our daily dietary intake has been known to reduce the risk of developing chronic diseases. The efficacy of these seasoning agents towards preventing or alleviating chronic diseases is facilitated through the synergistic effect of their secondary metabolites. A majority of the scientific reviews which have been conducted till present emphasise that the positive effects of culinary herbs and spices on human health is predominantly due to the presence of dietary polyphenols. This review however will focus on the therapeutic benefits of essential oils of culinary herbs and spices from the genera Curcuma and Zingiber in the management of Type 2 Diabetes Mellitus and Alzheimer’s Disease.

ABSTRACT The present study investigated the antibacterial, antifungal and allelopathic activities of Pistacia lentiscus essential oils (EOs) isolated at the vegetative, flowering and fructification stages. The chemical composition of EOs varied according to both the phenological stages and the used mix plant parts. The main chemical class was sesquiterpene hydrocarbons with the predominance of germacrene D, δ-cadinene and β-caryophyllene. The antibacterial activity was evaluated against five collection strains. At the vegetative stage, P. lentiscus EO was the most effective against Listeria monocytogenes and Echerchia coli as compared to the other stages. P. lentiscus EO also exhibited significant antifungal activity against the phytopathogenic strain Botrytis cinerea. Microscopic observation showed that EO induced swelling and crumbling of B. cinerea conidia. Moreover, P. lentiscus EO at the vegetative stage possessed significant allelopathic activity by inhibiting low concentration the germination and radical elongation of Raphanus sativus and radical elongation of Lepidium sativum.
