The qualitative and quantitative composition of four types of cinnamon bark (Cinnamomum) was studied by gas chromatography with mass spectrometric detection.Found in these samples were 72 compounds of various classes, including terpenes, aldehydes, alcohols, organic acids, coumarins, esters, catechins, vitamins, sterols, and sugars. As a result of the comparative analysis, the specific compounds were found that are characteristic for Cinnamomum zeylanicum (3-tuyen, 4 (10) -tuyen, eugenol, (-)-α-curcumen, linolenic acid and for a group of Cinnamomum burmannii, Cinnamomum loureiroi and Cinnamomum Cassia, namely, sativene, isosativene, longicyclene, β-elemen, γ-mourolen, α-mourolen, α-calacorene, syrinaldehyde, and syringol. The presence of common compounds with certain concentration variability was revealed for all four types of cinnamon. The selection of the most informative compounds allowing species differentiation of the cinnamon bark has been carried out by the method of main components. Among these, four components (eugenol, α-mourolen, syrinaldehyde and linolenic acid) and specific and 12 components, such as cinnamic aldehyde, α-fellandrene, limonene, linalool, copaene, caryophyllene, coumarin, benzyl benzoate, cinnamic acid, palmitic acid, linoleic acid, and disaccharides, have common origin. Further research will be directed toward establishing the criteria that would allow species differentiation of the cinnamon bark of Cinnamomum zeylanicum, Cinnamomum burmannii, Cinnamomum loureiroi and Cinnamomum Cassia types.

The qualitative and quantitative composition of two species of Oplopanax root was studied by gas chromatography with mass spectrometric detection. Extraction of components from the investigated objects was carried out by extraction of dry ground raw material with 70% ethanol. For the analysis of polar compounds, the extracts were further derivatized to give the corresponding trimethylsilyl derivatives. Identification of components was carried out using commercial (NIST17, Wiley14) and own custom mass-spectrometer libraries. The percentage of components found was calculated using the areas of the corresponding chromatographic peaks. Found in these samples were 130 compounds of various classes: terpenes and their derivatives, alcohols, aldehydes, polyyns, polyenes, various acids and their derivatives, phenols, sterols, lignans, vitamins, nucleosides, glycosides and sugars. It has been established that the qualitative and quantitative composition of root extracts varies even within the same species. The presence of 26 compounds common to the two species of Oplopanax, including 12 acids, 3 polyyns, 6 terpenes and one representative each from the class polyenes, aldehydes, lignans, glycosides and sterols, was revealed. As a result of the comparative analysis, it was established that 4 compounds from the class of polyyns (falcarindiol acetate, oplopanediol acetate, oplopantriol A and oplopantriol B) are found only in the roots of O. horridus.

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.

Использование растительных масел в рационе человека необходимо для удовлетворения энергетической потребности организма и регулирования биологических процессов. В настоящей работе представлен качественный и количественный состав витаминов и токоферолов различных видов растительных масел, полученных холодным отжимом из выращенных в нашей стране расторопши, горчицы, подсолнечника, рыжика, рапса. Проведен сравнительный анализ литературных источников о наличии витаминов и токоферолов в различных растительных маслах. Количественный и качественный витаминный состав для одного и того же вида масла, по данным разных авторов, варьируется в достаточно широком диапазоне. В ходе исследования изучен витаминный состав пяти растительных масел. Результаты свидетельствуют, что наибольшей витаминной активностью обладают масла рыжиковое, расторопши и горчичное. Установлено наличие витамина А в маслах: рыжиковом (27,15±0,002 мкг%), расторопши (19,07±0,02 мкг%), горчичном (24,77±0,02 мкг%). Витамины В и В присутствуют в маслах горчичном, рыжиковом и расторопши; витамин В определен в горчичном и рыжиковом, В - в рыжиковом и расторопши. В маслах горчичном и расторопши присутствует витамин В. Наиболее богаты витамином Е масла рыжиковое (52,8±0,02 мг%), подсолнечное (48,3±0,02 мг%), расторопши (47,12±0,02 мг%). Витамин К и токоферолы определены во всех растительных маслах. Присутствие b-каротина обнаружено в рыжиковом (1,237±0,004 мг%), расторопши (0,812±0,002 мг%), подсолнечном (0,22±0,02 мг%) и горчичном (0,148±0,002 мг%) маслах. Анализируемые масла холодного отжима можно рассматривать как ценный источник при проектировании новых многоцелевых продуктов или побочных продуктов для промышленного, косметического и фармацевтического использования. 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. The analyzed cold-pressed oils can be considered as a valuable resource when designing new multipurpose products or by-products for industrial, cosmetic and pharmaceutical applications.

Most cities in major agglomerations in Europe started to address the rise of short-term accommodation rentals by introducing regulation designed to protect the local housing stock. The momentum behind the widespread introduction of such regulations can be attributed to qualitative and quantitative factors. This article examines selected fields related to short-term rentals in order to uncover the (structural) triggers or conditions that are necessary and sufficient for municipalities to initiate the regulation of their housing market. The study is based on the systematic examination of the effects of those triggers and their combinations using qualitative comparative analysis (QCA). With this method, we explore the implementation or non-implementation of regulation on a sample of major German cities. The results suggest a universal set of conditions covering three central fields: housing market situation, accommodation market conditions and tourism accommodation demand.
