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.

ABSTRACT Main chemical compositions of essential oil (EO) from Litsea cubeba fruit collected in Kon Tum Province of Vietnam were geranial (32.0%), neral (24.3%), citronellal (14.2%), and limonene (10.1%). Twenty-four compounds of the EO were identified and compared with those from EOs previously reported in India, China, and Malaysia. Minimal inhibitory and bactericidal concentrations (MIC and MBC) indicated that the EO induced high levels of growth inhibition and moderate bactericidal activity against seven test Helicobacter pylori strains, including six strains resistant to one to four antibiotics, azithromycin, erythromycin, levofloxacin, and metronidazole. The bacterial biofilm formation was significantly suppressed by the EO at 1/2 and 3/4×MIC. The EO also exerts inhibitory activity against H. pylori-urease and convert a spiral form of H. pylori into a coccoid form. Fruit EO inhibits bacterial growth via both contact and fumigant action.

ABSTRACT Artemisia kanashiroi, is an important aromatic medicinal plant that is endemic to China. In the study, the chemical components of essential oil (EO) of A. kanashiroi obtained from different regions in China were analyzed. The results indicated that oxygenated monoterpenes are the predominant components of all EOs, and the major components were 1,8-cineole, camphor, terpine-4-ol, α-terpineol and spathulenol. The chemical composition of EOs exhibited ecological diversity driven by geographical factors. Furthermore, we evaluated the in vitro biological activities of the EOs, including their antioxidant and antibacterial activities. All of the EOs exhibited moderate to potent, broad-spectrum antibacterial and antifungal activities targeting both Gram-positive and Gram-negative bacteria. However, none of the EOs showed significant activity against the tested fungal strains. The antioxidant activity of the EOs was evaluated based on their scavenging activity against 2, 2-diphenyl-1-picrylhydrazyl (DPPH) free radicals, and all of the EOs showed significant concentration-dependent DPPH free radical scavenging activity.

ABSTRACT This study aimed to describe the chemical composition of the essential oil (EO) of stems, leaves and flowers of A. maritima collected from Turkey, and verify its antimicrobial and antioxidant properties. The EO was analyzed by GC-FID and GC-MS. Fifty-nine compounds representing to 98.1% of the EO were identified. The antimicrobial activities were determined against seven bacteria and two yeast species by using disc diffusion and MIC techniques. According to the results, it was observed that there was no effect of the EO against Gram-positive bacteria. The EO showed a low effect (8–9 mm) against Gram-negative bacteria, but the EO had a high effect (20–22 mm) against the tested fungi. In addition, according to the MIC test results, the EO presented effects against C. krusei, C. parapsilosis at a concentration of 50 µl/ml. The antioxidant activity of the EO was determined as IC50 = 31.9 µl/mL.

ABSTRACT The post-harvest stage of crops aims to minimize losses occuring during storage and commercialization. Drying process are some of the most used methods to minimize those losses. This work aimed at studying the drying kinetics of cinnamon (Cinnamomum zeylanicum), subject to two different drying conditions, one of which in an experimental fixed-bed dryer relying on an ambient air and speed of 0.5 m s−1, and the other with a forced air circulation oven at different temperatures (313.5, 323.15, 333.15 and 343.15 °K). The time required to reach the moisture equilibrium contents was 1.42, 3.0, 6.41, 14.0 and 21 h for drying temperatures of 343.15, 333.15, 323.15, 313.5 and 307.95 ºK, respectively. The Arrhenius equation described the diffusivity’s dependence on temperature, defining the activation energy of 64.77 kJ mol−1. The essential oils of the samples were analyzed through gas chromatography, which identified 23 individual compounds being eugenol the most abundant.

ABSTRACT The leaf oil from Baccharis punctulata D.C. specimens from Argentina, analyzed by GC and GC/MS during a one-year phenological cycle, showed important changes. In spring and summer, during the stem and floral bud development, the percentages of amorpha-4,7(11)-diene, amorpha-4-en-7-ol, amorpha-4,7-diene-11-ol and amorpha-4,7(11)-dien-8-one increased, while the percentage of verboccidentafuran decreased (c.a. 50% to 10%). The percentage of the guaiane alismol, which was negligible in other months, also increased (19.1–24.8 %). Alismol structure was spectroscopically established. Interesting, when buds opened, alismol percentage fell, so pre- and full-flowering oil composition resulted very different. Germacra-1(10),5-dien-4α-ol (16.7–23.0 %), verboccidentafuran (16.1–18.4%) and elemane-type sesquiterpenes were main components at flowering. Germacra-1(10),5-dien-4α-ol may have the adequate configuration and conformation to be biosynthetically related to alismol. Finally, germacra-1(10),5-dien-4α-ol and elemene derivative percentages decreased. Verboccidentafuran (27.6–52.4%) was the main compound in winter. These cyclic changes appear to be associated with the phenological stages of the plant during the year.
