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.

ABSTRACT α-Terpineol, a monocyclic monoterpenoid tertiary alcohol with lilac-like aroma, is found in a variety of plant essential oils. Current research has revealed that α-terpineol has a varied range of biological activities including antioxidant, anti-inflammatory, antimicrobial, anticancer, analgesic, gastroprotective, cardioprotective, neuroprotective, and antidiarrheal effects. These beneficial activities of α-terpineol coupled with its unique aroma and safety offer the possibility of incorporating this compound into food, cosmetic, non-cosmetic, medical, agricultural, and chemical industries. Hence, this paper summarizes the sources and production of α-terpineol, and focuses on the biological properties so far described for α-terpineol and its mechanism of action. Furthermore, the safety of α-terpineol, industrial applications and directions for future α-terpineol research are discussed. This paper provides reference for the research and application of α-terpineol in the future.

ABSTRACT The aim of this study was to verify the seasonal influence on the Eugenia uniflora essential oils. The collections were carried out in October 2017 and March, May and August 2018. The extraction of the essential oils was performed by hydrodistillation and their composition was determined by gas chromatography. The yield of the essential oils was lower in winter (1.04% m/m). The composition of the essential oils in the different seasons did not change in relation to their compounds, differing only in their amounts. Germacrone was identified as the main compound, having a higher percentage in spring (48.05%) and summer (45.00%). Antioxidant activity (DPPH) may have been influenced by the higher percentages of germacrone, with better inhibitory concentration values (IC50) in summer (0.62 mg/mL), followed by spring (0.98 mg/mL). The E. uniflora essential oils tested have moderate to weak antibacterial activity and were more efficient against Escherichia coli.

ABSTRACT Black (Piper nigrum L.) and cubeb pepper (Piper cubeba L.) fruits from the Serbian market were chosen as unprocessed materials for obtaining market-valuable essential oils. Since pepper fruits are only imported in Serbia, inadequate transportation and storage conditions may lead to their spoilage, negatively affecting their quality as feedstocks. To ensure the highest quality of essential oils, fruits were refrigerated upon purchase, mechanically disintegrated at colder conditions and subjected to hydrodistillation. Black (BPEO) and cubeb pepper essential oil (CPEO) contained 34 and 42 compounds, respectively. CPEO showed better inhibitory effect on B. cereus (ATCC strain) and C. albicans (isolate and ATCC strain). Both oils were not bactericidal against B. cereus (isolate and ATCC strains) and S. enterica (isolate). The best antioxidant properties were shown after 1 h of incubation. These results are valuable for further progress, development and production regarding the aromatic plant industry, pharmaceutical and food industry.

ABSTRACT A combined volatile oil (VO) was extracted from Rosmarinus officinalis, Lavandula angustifolia and Citrus aurantium by simultaneous hydro- and steam-distillation, and encapsulated in β-cyclodextrin by co-precipitation. Response surface methodology (RSM) was used to optimize microencapsulation conditions. The variable recovered powder, VO retention degree, and inclusion efficiency were investigated based on two factors: solid-to-liquid and liquid-to-liquid (ethanol/water) ratios. The responses were influenced by the concentration of ethanol in the reaction mixture and the amount of VO used. VO release from the inclusion complexes was investigated in 10% ethanol and in 3% acetic acid. The obtained data were fitted to the first-order Korsmeyer-Peppas, Higuchi, and Peppas-Sahlin models. The Higuchi model gave the fittest approach for the VO release profile in both cases, showing that the release mechanism was controlled by Fickian diffusion.

ABSTRACT The present study aimed to characterize the chemical composition and evaluate the antioxidant and antibacterial activities along with the absorption, distribution, metabolism, excretion, toxicity (ADMET) study of the essential oil of Ziziphora hispanica (ZH-EO), collected from the Middle Atlas of Morocco (Boulmane). Results showed that a total of 119 volatile components, characterized by GC-FID and GC-MS analysis, which represents the 88.7% of the total of ZH-EO. ZH-EO displayed a bactericidal effect against Listeria monocytogenes, Pseudomonas aeruginosa and Enterococcus faecalis, and a bacteriostatic effect against Staphylococcus aureus. Furthermore, ZH-EO exhibited strong antioxidant activity against DPPH radical (IC50 = 1.3 mg/mL). The ADMET prediction showed good pharmacokinetic properties of the tested components. The findings obtained from this study suggest that Ziziphora hispanica essential oil could represent a source of bioactive molecules with antioxidant and antibacterial potential in the prevention against diseases related to oxidative stress and pathogenic bacteria.

ABSTRACT Plants produce variety of secondary metabolites in response to stress. The study aimed to evaluate the soil moisture stress on oil content & composition of German chamomile conducted in, 2020 and 2021 at CSIR-Central Institute of Medicinal and Aromatic Plant, Research Centre, Pantnagar, Uttarakhand, India. The treatments were T1 (just before irrigation), T2 (24 h after irrigation), T3 (72 h after irrigation), T4 (120 h after irrigation), and T5 (168 h after irrigation). Results showed that maximum oil content (0.26 & 0.57 ml/100g) was found in fresh and dry flowers, respectively of T2 & oil content decreased as the days to irrigation increased. GC results showed that the percentage of major compounds was lowest (74.02%) while maximum in acute drought conditions i.e. before irrigation (92.12%). Results suggest that soil moisture stress reduces the oil content however, the quality of oil is enhanced due to increased production of secondary metabolites.
