The procedure of Salvia przewalskii shoot multiplication and the ability of regenerated plants to produce essential oil is reported. The essential oil was obtained by hydrodistillation from leaves and flowering stems of field-grown plants, and their chemical composition was examined by GC, GC-MS and 1H NMR. The differences in yield as well as qualitative and quantitative composition between the oils isolated from in vitro and in vivo plants were observed. S. przewalskii essential oil was tested for its antimicrobial and cytotoxic properties. It was found that cytotoxicity against human leukemia HL-60 cells and antimicrobial activity (especially, against Staphylococcus aureus and S. epidermidis strains) of oils isolated from in vitro plants were higher than those for oils from in vivo S. przewalskii plants.

The essential oils were isolated by hydrodistillation from the hairy roots (HR) and roots of soil-grown plants (SGR) of Rhaponticum carthamoides and were analyzed by GC-MS method. In the both essential oils 62 compounds were identified. The root essential oils showed the differences in the qualitative and quantitative composition. The sesquiterpene hydrocarbons (55–62%) dominated in both essential oils. The major compounds of HR essential oil were cyperene, 13-norcypera-1(5),11(12)-diene, and cadalene while aplotaxene, nardosina-1(10),11-diene, and dauca-4(11),8-diene dominated in SGR essential oil. Both essential oils showed antibacterial activity especially against Enterococcus faecalis (ATCC 29212) and Pseudomonas aeruginosa (ATCC 27853) (MIC value = 125 µg/mL). HR and SGR essential oils also decreased the expression of IL-1β, IL-6, and TNF-α and the ROS level in LPS-treatment astrocytes. This is the first report to describe the chemical composition of R. carthamoides essential oil from hairy roots, its protective effect against LPS-induced inflammation and ROS production in astrocytes, and its antimicrobial potential. The results show that R. carthamoides hairy roots may be a valuable source of the essential oil and may be an alternative to the roots of soil-grown plants.

The Impact

Introduction. Much attention is paid to the production of green products of aromatic plants from local raw materials, as one of the priorities implemented under the program “The Concept of the State Policy in the Field of Healthy Nutrition of the Population of the Russian Federation for the Period until 2020”. For the year-round consumption of green mass of plants, there are used different technologies of cultivation. Specific growing conditions (short light day and low light) in the autumn-winter period of highly productive plants in our country are possible only with the use of additional sources of artificial light. Material and methods. Studies of the effect of different growing technologies on the component composition of essential oil and volatile plant excreta using the example of peppermint carried out by chromatography-mass spectrometry with analytical complex «Clarus 600M» by Perkin Elmer (USA) (flame ionization) and mass spectrometry detectors with gas chromatography-mass spectrometry system Focus GC DSQ II by Thermo Scientific (USA). Results. The use of new technologies for growing ether-bearing plants may cause a change in the qualitative and quantitative composition of the essential oil and volatile plant excretions. Because of re-lighting by narrow cavity light, there have been changes in the qualitative and quantitative composition of the essential oil and volatile mint emissions. The disappearance of sabinene, bourbonene, myrtenol, colamen found in control samples and the formation of cumene, 3-hexyl-2-methylbutyrate, germacrene, carvone, cubenol, a decrease in the content of the main components: menthol, menton, benzyl alcohol, sabinene, bourbonene; an increase in the content of methylacetate, isomentone, isomenthol, neomentilacetate. With combined lighting, a reduction from 43 to 31 compounds was established with a decrease in their total content in the composition of the volatile fraction. Conclusion. Terpene hydrocarbons are the most hygienically significant substances belonging to the group of easily transformed substances, and oxygen-containing compounds (aldehydes, ketones, phenols, furans, pyrans, ethers) identified in the group of toxic and dangerous chemicals

The purpose of this work is to evaluate the effectiveness of using supercritical carbon dioxide extraction to obtain essential oils from exocarpy of Meyer lemon in comparison with the pressing method. The plant material is represented by the exocarpy of Meyer lemon Citrus meyeri Tan., Rutovye family – Rutaceae, collected in the vicinity of Khujand (Republic of Tajikistan), in November 2014. Supercritical carbon dioxide extracts (CO2 extracts) were obtained at the Research Center for Ecological GORO resources (Rostov-on-Don) at the KOERS1 installation. As a comparison, we used the essential oil obtained by direct pressing on hydraulic presses without heating. Qualitative and quantitative analysis of the components was carried out by gas chromatography with chromatography-mass spectrometric detection. As a result of the study, it was found that the optimal parameters of CO2 extraction, which provide the highest content of limonene and γ-terpinene in the extract, are: 50 °С, 16 MPa, and 30 min. A comparative analysis of the content of extract components showed that the yield of limonene during supercritical extraction, compared with traditional technology, increased by 7.5%, the γ-terpinene content was 1.5 times. In addition, significant differences were found in the qualitative and quantitative composition of the essential oil and the CO2 extract of Meyer lemon. In essential oil, the content is higher: α- and β-pinene, p-cumene, geranial, and others. In the CO2 extract, the content is higher: sabinene, α-humulene, β-bisabolene and other low-volatile compounds, with an additional 9 components: α-thuen, terpenolene, geranyl acetate, etc., which indicates the need for an additional pharmacological study of the CO2-extract of Meyer lemon.

The anti-oxidative and antimicrobial activities of different extracts from Hieracium pilosella L. (Asteraceae) whole plant were investigated. The total dry extracts were determined for all the investigated solvents: methanol, dichloromethane, ethyl acetate and dichloromethane: methanol (9:1). It was found that the highest yield was obtained by extraction with methanol (12.9 g/100 g of dry plant material). Qualitative and quantitative analysis were performed by the HPLC method, using external standards. Chlorogenic acid, apigenin-7-O-glucoside and umbelliferone were detected in the highest quantity in the extracts. The qualitative and quantitative composition of the extracts depends on the solvent used. The 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging effect of the extracts was determined spectrophotometrically. The highest radical scavenging effect was observed in the methanolic extract, both with and without incubation, EC50 = 0.012 and EC50 = 0.015 mg ml-1, respectively. The antimicrobial activities of the extracts towards the bacteria (Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, Bacillus subtilis, Salmonella enteritidis and Klebsiella pneumoniae) and the fungi (Aspergillus niger and Candida albicans) were determined by the disc diffusion method. The minimal inhibitory concentrations were determined for all the investigated extracts against all the mentioned microorganisms.

The properties ofBoswelliaplants have been exploited for millennia in the traditional medicines of Africa, China, and especially in the Indian Ayurveda. In Western countries, the advent of synthetic drugs has obscured the pharmaceutical use ofBoswellia, until it was reported that an ethanolic extract exerts anti-inflammatory and antiarthritic effects. Frankincense was commonly used for medicinal purposes. This paper aims to provide an overview of current knowledge of the volatile constituents of frankincense, with explicit consideration concerning the diverseBoswelliaspecies. Altogether, more than 340 volatiles inBoswelliahave been reported in the literature. In particular, a broad diversity has been found in the qualitative and quantitative composition of the volatiles with respect to different varieties ofBoswellia. A detailed discussion of the various biological activities ofBoswelliafrankincense is also presented.

The use of vegetable oils in the human diet is necessary to meet the energy needs of the body and regulate biological processes. This work presents the qualitative and quantitative composition of vitamins and tocopherols of various types of vegetable oils obtained by cold pressing from silybum marianum, mustard, sunflower, camelina, rapeseed grown in our country. A comparative analysis of the literature on the presence of vitamins and tocopherols in various vegetable oils has been carried out. The quantitative and qualitative vitamin composition for the same type of oil, according to different authors, varies in a wide range. During the study, the vitamin composition of five vegetable oils was studied. The results indicate that the following oils have the highest vitamin activity: camelina, silybum marianum and mustard. The presence of vitamin A was found in oils: camelina (27.15±0.002 μg%), silybum marianum (19.07±0.02 μg%), mustard (24.77±0.02 μg%). Vitamins B and B are present in mustard, camelina and silybum marianum oils; vitamin B is found in mustard and camelina; B in camelina and silybum marianum. Mustard and silybum marianum oils contain vitamin B. The richest in vitamin E are camelina (52.8±0.02 mg%), sunflower (48.3±0.02 mg%), silybum marianum (47.12±0.02 mg%). Vitamin K and tocopherols are found in all vegetable oils. The presence of b-carotene was found in camelina (1.237±0.004 mg%), silybum marianum (0.812±0.002 mg%), sunflower (0.22±0.02 mg%) and mustard (0.148±0.002 mg%) oils.
