The purpose of this study was to determine the content of carotenoids in the fruits of some representatives of Sorbus genus from the collection of the South Ural Botanical Garden-Institute. For the quantitative analysis, the fruits of the rowan trees were collected in the phase of full ripening and dried to an air-dry state. Sorbus aucuparia L. was used as an object of comparison as the official pharmacopoeias species. Qualitative detection of carotenoids was performed by thin layer chromatography, quantitative determination - spectrophotometrically.It was found that the highest content of carotenoids is characterized by a sort of hybrid origin × Crataegosorbus miczurinii “Garnet” – 46.41 mg/% and a natural hybrid Sorbocotoneaster pozdnijkovii – 42.64 mg /%. The minimum content of this group of substances is noted in the raw material of Sorbus frutescens (0.86 mg/%) with white fruits. This fact is confirmed by the presence of plant pigments – carotenoids, in fruits that have a yellow-orange-red color. The local Sorbus aucuparia had a low carotenoid content (11.24 mg/%).The study, with a certain degree of reliability, suggests the presence of carotenoids in the fruits of the rowan trees studied and allows us to recommend them as a promising source of raw materials for the production of vitamin-active drugs and food additives. The studied taxons × Crataegosorbus miczurinii and × Sorbocotoneaster pozdnijkovii are characterized by high introduction resistance under the conditions of the Bashkir Cis-Urals. In the future, it is intended to continue the study of other members of the Sorbus genus for the presence of pharmacopoeias properties.

Abstract Lonicera caerulea L., also known as honeysuckle berries, are rich in biologically active compounds, which makes them a valuable raw material for the development of functional foods. The objects of the research were three honeysuckle cultivars (‘Zoluška’, ‘Siņaja Ptica’, ‘Goluboje Vereteno’), four genotypes (No 2A; No 3; No 5; No 8) and kefir, enriched with various amounts (3–10%) of fruit puree. Physical and chemical analyses to determine the qualitative indicators of raw materials and products were performed. The degree of liking of kefir was assessed using sensory analysis: hedonic and line scales. The results obtained showed that among the cultivars the highest content of anthocyanins (1103.5 mg·100 g−1), total phenols (693.3 mg·100 g−1), flavonoids (753.9 mg·100 g−1), and tannins (1.6 mg·100 g−1), were found in ‘Siņaja Ptica’ berries, while among the genotypes, berries of No 8 had the highest concentration of the aforesaid compounds. Both samples also showed the highest antiradical activity: ABTS+• on average by 71.7% and DPPH− by 43.7%. According to the sensory evaluation, kefir with 10% honeysuckle puree was rated the highest. Honeysuckle berries could be used as a promising source of natural anti-oxidants in future research aimed at developing different new products that could meet consumer expectations.

Background. Oils of hemp and cotton presently have reduced retail trade offer in Russia, but are widely produced and used. Industrial hemp is still cultivated and processed domestically. In the 1950s, industrial cotton was cultivated on a hundred thousand hectares in the country, and now there are signs of its restored growing. Both crops have the ability to restore the raw material base to produce textile fibers, seed and oil as well as the potential to improve functional food production, because they contain functional food ingredients in their oil capable of reducing human nutrition disorder risks, preventing or restoring nutrient deficiencies, preserving and improving health.Materials and methods. Unsaturated and polyunsaturated fatty acids’ profiles of hempseed (Cannabis sativa L.) and cottonseed (Gossypium hirsutum L., G. herbaceum L., G. barbadense L.) oils were evaluated. Seeds were grown respectively under the conditions of the Russian North-West (hemp) and Adler District, Krasnodar Territory (cotton). The PUFA profile was measured using gas chromatography with mass spectrometry equipment (Agilent 6850, USA). All data were calculated using the UniChrom software.Results and conclusions. The content of the omega-6 linoleic acid in hemp accessions reached 64.2%; omega-3 alpha-linolenic acid, 27.1%; monounsaturated oleic acid, 14.0%. The sum of unsaturated acids was 94.2%; and that of polyunsaturated ones, 87.2%. Compared with hemp oil, cotton oil had a lesser sum of polyunsaturated (maximum 58.0%) acids, while its unsaturated acids were up to 79.0%. Oleic acid was found to reach 22.7% in cottonseed oil. Industrial cultivation of hemp and cotton in Russia need not be limited to textile fiber production, but may serve as a potential base of vegetable oils and food; just because of their PUFA contents, it is promising for the production of functional food ingredients, which have health benefits in reducing the risk of cancer and cardiovascular diseases, lowering the HDL cholesterol levels, and relaxing the smooth muscle cells in arteries, thus increasing the blood flow. Seed cake may be valuable addition to animal feed rations as well. As a result of the evaluations, valuable accessions (cultivars and lines) of hemp and cotton were identified. Although the selected accessions are not the products of previous breeding efforts aimed at the PUFA content improvement, they are promising source materials for the development of new cultivars with seeds enriched with compounds or sets of compounds that provide a beneficial effect on human health when included in the composition of food products (functional food ingredients).

The homeland of Myrthus communis L. is Mediterranean region, in the countries of which its wild-growing and cultivated varieties grow. In the collection of the Nikitsky Botanical Gardens – National Scientific Center of the Russian Academy of Sciences the economic-valuable and morphological features of nine cultivars of this species have been studied. The plant is considered as a promising industrial medicinal culture. Contamination of medicinal plants with heavy metals and other toxic elements is an existing problem, which is associated with serious concern of international organizations on the quality and safety of medicinal raw materials. It is now established that trace constituents, entering into connection with chemical regulators of metabolism, including amino acids, participate in various biochemical processes, stimulate and normalize metabolism. The objective of this work is to study the elemental and amino acid composition of leaves of Myrthus communis L., cultivated in the Nikitsky Botanical Gardens. The study of Myrthus communis L. ultimate composition has been done with due regard to General Monograph requirements "The identification of heavy metals and arsenium in medicinal raw materials and plant preparations" for State Pharmacopeia of XIII edition. The research of the amino acid profile has been done subject to State All-Union Standard 32195-2013 (ISO 13903:2005). As a result of research it has been established that leaves of Myrthus communis L. accumulate 28 elements and 16 amino acids. The content of heavy metals and arsenium in the studied samples did not exceed the maximum permissible values for medicinal plant raw materials established by the Russian State Pharmacopoeia. The total content of amino acids in the leaves of myrtle was 11.65%. Among the amino acids found, glutamic and aspartic acids prevailed. The least in the leaves was methionine. The obtained results will be used for follow up standardization of myrtle raw materials as a promising source of medicinal plant raw material.

Abstract A field trial with Miscanthus sinensis Anderss. was performed in Vysoká nad Uhom (average yearly temperature: 9.0°C, yearly precipitation: 584 mm) on Haplic fluvisol (WRB 2006) during 2006-2009. The average dry matter (DM) yield of the above- ground phytomass was 25.63 t/ha/year (excluding establish- ment year when yield was 4.81 t/ha) and had an increasing trend according to production years (14.13, 26.14 and 36.63 t/ha). We achieved in developing a trial stand in the third year of production when the field coverage of 10 thousand rhizomes being planted per hectare was over 80%; however, it can be used as a denser spacing for the earlier performance of stand with full production capability, which means plantation of 12-13 thousand plants per hectare. The average lower heating value of the organic sample of phytomass, as received (LHV) was 15.56 MJ/kg, and according to the trial years were 15.09; 15.80; 15.70; and 15.80 MJ/kg. The amount of total energy value of the produced phytomass per unit area (energy yield) was 1,284.989 GJ/ha, and 72.583, 223.254, 410.398, 578.754 GJ/ha, respectively, in the trial years. The energy yield was exclusively affected (r = 0.999), and the caloric value (LHV) was affected by phytomass yield (r = 0.739). Obtained emission characteristics and the concentration of selected volatiles, and remaining ash, ash content 3.46%, total water 10.65%, carbon 42.49%, hydrogen 5.20%, total sulphur 0.12%, nitrogen 0.55%, silicone 1.17% and chlorine 0.16% have supported the environmentally friendly introduction of Chinese silvergrass, as the energy crop is desirable for the targeted agroecological conditions of Slovakia.

Biomass is doubtless a very significant source of renewable energy being worldwide abundant with high energy potential. This paper deals with assessment energy consumption at especially grinding and briquetting processes, which should result in essential economy of energy at solid biofuel production. Various types of raw materials were used at the experiment such as hemp (Cannabis sativa L.) biomass, two species of Miscanthus (Miscanthus sinensis, Miscanthus x gigantheus) and apple wood biomass. These materials were dried, grinded and pressed by piston press having pressing chamber diameter of 65 mm. Materials were grinded into three fractions (4 mm, 8 mm and 12 mm). Material throughput (kg.h-1) and energy consumption (kWh.t-1) were registered. As to results: the highest throughput at both grinding cases as well as briquetting was found at apple wood biomass; however the energy consumption during briquetting of apple wood was relatively high. The worst results concerning throughput and energy consumption (especially at briquetting) were found at hemp biomass. Nevertheless, briquettes made of hemp had the best mechanical durability. Both Miscunthus species (herbaceous biomass) have very similar parameters and showed quite good relation between throughput and energy consumption at the used machines.
