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.

ABSTRACT This study illustrates the importance of multivariate analysis in profiling the levels of 104 volatiles across 14 modern rose cultivars obtained using headspace gas chromatography–mass spectrometry analysis. Despite differences in the abundance of volatiles, the cultivars ‘Lady Emma Hamilton’, ‘Golden Celebration’ and ‘The Poet’s Wife’ share similar profiles of volatile organic compounds (VOCs) and the absence of phenethyl alcohol, which is usually associated with a characteristic ‘rose’ fragrance. R. ‘Hansa’ is the cultivar with the greatest abundance of volatiles, with high levels of acyclic monoterpenes and aromatic compounds. No monoterpenes were detected from the climbing rose R. ‘August Gervais’. The study revealed that highly fragrant cultivars tend to produce VOCs in higher intensity and greater diversity. These findings also demonstrate the potential of using headspace analysis to compare the natural aromas of rose cultivars, which provides information to inspire innovation in the perfumery and food industries.

摘要:本研究阐明了利用顶空气相色谱-质谱分析方法对14个现代玫瑰品种的104种挥发物含量进行多元分析的重要性。尽管挥发物含量不同，但“Lady Emma Hamilton”、“Golden Celebration”和“the Poet’s Wife”这三个品种的挥发性有机化合物(VOCs)含量相似，而且不含苯乙醇，而苯乙醇通常与特有的“玫瑰”香味有关。R. ' Hansa '是挥发物最丰富的品种，挥发物含量高，无环单萜烯和芳香化合物含量高。月季‘August Gervais’中未检测到单萜类化合物。研究表明，高香品种产生的挥发性有机化合物强度更高，多样性更大。这些发现也证明了利用顶空分析来比较玫瑰品种的天然香气的潜力，这为激发香水和食品工业的创新提供了信息。缩写AMT，无环单萜;ARM:芳香化合物;CMT，环单萜;GLV:绿叶挥发物;HEX, C6脂质衍生物;OTH，其他挥发物;主坐标分析;PEA，苯乙醇;RI:保留指数;SSQ,倍半萜烯;TD-GC-MS，热解吸-气相色谱-质谱;VOC，挥发性有机化合物。图形抽象

ABSTRACT Fourteen hexane-soluble polyphenolic secondary metabolites were previously isolated as individual compounds from Empetrum nigrum L. and identified as three bibenzyls, four 9,10-dihydrophenanthrenes, two chalcones, four dihydrochalcones and one flavanone. In this study, the mass-spectra and retention indexes (RI) of compounds 1-14 without prior derivatization were obtained and the resulting fragmentation pathways rationalized in accordance with literary data and the compounds structures. Preliminary differences in metabolite composition were assessed by comparative profiling using GC-MS chromatography combined with multivariate data analysis for a limited amount of E. nigrum n-hexane extracts obtained from plants growing in three different geographic locations. To characterize antioxidant capacity of isolated compounds 1-14 we used our well-established model based on reactive oxygen species (ROS) production by activated human platelets and showed that most of the examined polyphenols act as antioxidants by inhibition of ROS production.

ABSTRACT The Myrtaceae family has 121 genera and about 3800 to 5800 species distributed throughout the world, especially in tropical and subtropical countries. Many plants in this family found in the Amazon region produce essential oils with antioxidant, antimicrobial, and antiparasitic activities. In general, essential oils from Amazonian species of this family contain substances from the terpene class, including the monoterpene α-pinene and sesquiterpene β-caryophyllene, in addition to phenylpropanoids such as eugenol. However, the chemical composition and concentration of the major compounds can vary depending on the geographic location of the plants. This work compiles the most recent information on the chemical composition and biological activities related to the essential oils of several species belonging to the Myrtaceae family from the Amazon region, thus guiding future research.
