Abstract:
The cultivation of non-edible oil-bearing plants as feedstocks for the biodiesel production can aggressively take advantage of natural environments. Herbaceous non-edible oil-bearing plants have been significantly favored as an ideal feedstock for biodiesel fuel, though little is known about its industrial feasibility and environmental impact. The items with the greatest sensitivity in capital and ecology are land acquisition, plant life cycle, mechanical harvesting, fertilizer, control of weed, pests and diseases, seed yield and oil content. This study aims at analyzing the disadvantages of herbaceous non-edible oil-bearing plants and suggests impeding their industrial cultivation for the biodiesel production. The source of information for the proper selection of non-edible oil-bearing plants suitable as biodiesel feed-stocks has been the recent relevant literature. Herbaceous non-edible oil-bearing plants have a low phytoremediation potential and oil yield, but high weed potential. They occupy a large arable area while demand harder cultivation conditions and mechanical harvesting. Non-edible oils from woody plants are promising biodiesel feedstock. However, the weed potential of woody oil-bearing plants must also be considered to prevent their invasiveness.

Abstract:
The assortment of butter in Russia traditionally contained anhydrous butter produced by the method of knocking cream. At present, butter is produced to a greater extent by the conversion of high-fat cream. On the shelves of stores, besides the sweetening and acidic oils, you can see butter butter with the addition of additional flavor components. Fito components have high antioxidant properties and are widely used in the food industry. Introduction to the product of this recipe ingredient allows you to enrich the product with valuable nutrients and increase the stability of the latter when stored. The recipe of oil of the acidic and phytocomponents containing high-fat cream, leaven, salt, cooked phytocomponents, vitamins, stabilizer, emulsifier is proposed. The phytocomponent composition includes a dry mixture of parsley, dill and porridge. It is of interest to study the antioxidant activity of phyto-components. The dried parts of the plants were shredded to a particle size of 2.5 ± 1.5 mm. Plant extracts were obtained by maceration using distilled water. The extracts were filtered before the study. An indicator of the antioxidant activity of the aqueous extract of phyto-components was determined – 0.271 mg / g. A comparison of the obtained results with known indices of other plants is carried out. As the objects of comparison took the most used herbs in the food industry: sweet, saffron, thyme, St. John's wort, chamomile chemist, melissa. It has been established that the mixture of dill, parsley and porridge meal has a high antioxidant index and minimal restrictions when used. The optimal dosage of the mixture of herbs is 1.0 – 1.5 % and food cooking salt – 1 % (indicator according to GOST 32899–2014 for greenery and their mixtures is 0.5 – 8.0 %, for sodium chloride – no more than 2 %) The technology of production of oxygen-containing oil with phytocomponents is developed. The indicators of its quality have been studied, the shelf life of the oil has been determined.

Abstract:
Rose oil production worldwide is based on different oil-bearing Rosa species. This 4-year study determined the essential oil content, constituents, and morphologic/phenologic characteristics of 25 varieties, chemotypes, and hybrids belonging to five Rosa species (R. damascena Mill., R. gallica L., R. centifolia L., and R. alba L.). Limits of variation of these indices were established for each variety, chemotype, and hybrid group. The essential oil content of R. damascena varied from 0.032% to 0.049% and that of hybrid roses from 0.037% to 0.05%. The highest essential oil content was found in R. damascena accession Svejen 74 and the lowest in R. alba. Within R. damascena, the weight of single flowers varied from 2.09 to 3.44 g, the number of petals from 22 to 28, the height of the plants from 61 to 128 cm, and the diameter of bushes from 53 to 118 cm. R. centifolia had the largest flowers. The essential oil of the various species showed moderate to no antimicrobial activity at 50 μg/mL and no significant antibacterial, antifungal, antileishmania, or antimalarial activity at this concentration. All the tested species and accessions could be grown in Bulgaria (and possibly in southeastern Europe and the northern Mediterranean) and provide comparable productivity to the traditional species R. damascena. Wide variations occurred in essential oil content and constituents and morphologic/phenologic characteristics of the tested Rosa species and accessions. The availability of various species and chemotypes within specific species offer an opportunity for production of oil-bearing roses and essential oils to meet market requirements of specific rose oils.

Abstract:
Essential Oils (EOs) are expensive hydrocarbons produced exclusively by specific species in the plant kingdom. Their applications have deep roots in traditional herbal medicine, which lacks scientific evidence. Nowadays, more than ever, there is a growing global interest in research-based discoveries that maintain and promote health conditions. Consequently, EOs became a much attractive topic for both research and industry, with revenues reaching billions of dollars annually. In this work, we provide key guidance to all essential oil-bearing plants growing in the United Arab Emirates (UAE). The comprehensive data were collected following an extensive, up-to-date literature review. The results identified 137 plant species, including indigenous and naturalized ones, in the UAE, citing over 180 published research articles. The general overview included plant botanical names, synonyms, common names (Arabic and English), families and taxonomic authority. The study acts as a baseline and accelerator for research, industry and discoveries in multiple disciplines relying on essential oil-bearing plants.

Different systems of direct oil supply have been developed in order to facilitate efficient introduction of fresh lubricant to the oil gap and reduction of churning power loss in tilting pad thrust bearings. Up to now there is no documented application of the supply groove in large thrust bearings used in water power plants. The results of modeling lubricant flow in the lubricating groove of a thrust bearing pad will be presented in the paper. CFD software was used to carry out fluid film calculations. Such analysis makes it possible to modify groove geometry and other parameters and to study their influence on bearing performance. According to the results a remarkable decrease in total power loss due to avoiding churning losses can be observed in the bearing.

Abstract:
Phenolic and non-phenolic chemotypes of Thymus pulegioides L. are common in Europe. Essential oils of these chemotypes, as various compositions of allelochemicals, can have different phytotoxic effects on neighboring plants in natural habitats. The aim of this study was to establish the distribution of carvacrol and geraniol in T. pulegioides, growing wild in Lithuania, and compare phytotoxity of essential oils of carvacrol and geraniol chemotypes on selected plant species. In investigating 131 T. pulegioides habitats, essential oils were isolated by hydrodistillation and analyzed by GC-FID and GC-MS. Phytotoxity of essential oils extracted from carvacrol and geraniol chemotypes transmitted through water and air to selected plants was determined under laboratory conditions. Pharmacologically valuable Hypericum perforatum L. and the important forage grass Phleum pratense L. were respectively selected for experimentation from among 35 medicinal plants and 10 feed Poaceae species, growing in T. pulegioides habitats. Field results showed that carvacrol is common throughout Lithuania’s territory, whereas the geraniol is predominantly located under the continental climatic conditions of the eastern region of the country. In the laboratory experiment, it was established that there was stronger inhibition of P. pratense seed germination by the essential oil of the geraniol chemotype than the carvacrol chemotype. None of the H. perforatum seeds germinated after exposure to the essential oil of the geraniol chemotype. In general, this study builds on previous studies by providing further evidence that different T. pulegioides chemotypes have contrasting phytotoxic effects on neighboring plants within their natural habitats.

Abstract:
Tung tree (Vernicia fordii) is an industrially important oil-bearing woody plant of the Euphorbiaceae family. Functional studies of tung tree at the molecular level are limited by the lack of an efficient transgenic system. The Agrobacterium rhizogenes-mediated hairy root generation system is an alternative to typical plant transformation systems. However, its application in many plants has been blocked due to the inability of existing methods to induce hairy roots. Thus, it is critical to build a method suitable for the hairy induction of the specific plant of interest. In this study, a modified method for tung tree was developed, and it is the first report that hairy roots could be effectively induced in the stem of tung tree. With the method, an average of 10.7 hairy roots per seedling were generated in tung tree, approximately 67% of seedlings produced transgenic hairy roots and approximately 13.96% of the hairy roots of these seedlings were transgenic. This modified method is also suitable for the hairy root induction of two other oil-bearing plants of the Euphorbiaceae family, Ricinus communis and Vernicia montana. This modified method will accelerate functional studies of tung tree at the molecular level and also shed light on plants lacking a transgenic system.

Abstract:
Push for sustainability is evident in areas such as energy generation where the focus has been on finding new deposits to outpace drawdown on existing reserves. Gas flaring is employed by oil and gas industries to burn-off associated gasses from refineries, hydrocarbon processing plants or oil and gas reserve wells. It is one of the most taxing energies and environmental problems challenging the world today. Generally, safety flaring was dubbed as the saviour of process plants and mostly covers for sudden or unplanned plant trips. It is an opportunity to cut greenhouse gases (GHGs) from oil and gas processing plants through flare gas recovery (FGR) process. Oil and gas plants can employ diverse FGR procedures to offset key concerns about the environmental bearing of GHGs emanation most of which necessitating novel apparatus and extraordinary outlay of design and construction. In this study, apart from economic aspects, a real-life case study is extensively analysed to highlight exploration and adoption of optimizing FGR that may be beneficial if flare gas can be recovered, instead of burning. The output of the study may have a significant impact for refineries towards both economic and sustainability towards greening. In a nutshell, this study highlights the efficacy of reducing ‘flare gas system’ towards environment-friendly ‘greening’ aspect as the core of designing.

Abstract:
Currently, the negative effects of unified and intensive agriculture are of growing concern. To mitigate them, the possibilities of using local but nowadays underused crop for food production should be more thoroughly investigated and promoted. The soybean is the major crop cultivated for vegetable oil production in Zambia, while the oil production from local oil-bearing plants is neglected. The chemical composition of oils and cakes of a three traditional oil plant used by descendants of the Lozi people for cooking were investigated. Parinari curatellifolia and Schinziophyton rautanenii oils were chiefly composed of α-eleostearic (28.58–55.96%), linoleic (9.78–40.18%), and oleic acid (15.26–24.07%), whereas Ochna serrulata contained mainly palmitic (35.62–37.31%), oleic (37.31–46.80%), and linoleic acid (10.61–18.66%); the oil yield was high (39–71%). S. rautanenii and O. serrulata oils were rich in γ-tocopherol (3236.18 μg/g, 361.11 μg/g, respectively). The O. serrulata oil also had a very distinctive aroma predominantly composed of p-cymene (52.26%), m-xylene (9.63%), γ-terpinene (9.07%), o-xylene (7.97), and limonene (7.23%). The cakes remaining after oil extraction are a good source of essential minerals, being rich in N, P, S, K, Ca, and Mg. These plants have the potential to be introduced for use in the food, technical, or pharmaceutical industries.

Abstract:
In some cases, the oil shale deposited in shallow lakes may be genetically associated with the coal-bearing successions. Although paleovegetation is an important controlling factor for the formation of oil shale- and coal-bearing successions, few studies have focused on their joint characterization. In this study, a total of twenty-one oil shale and coal samples were collected from the upper member of the Lower Cretaceous Muling Formation (K1ml2) in the Laoheishan Basin, and investigated for their bulk geochemical, maceral, palynological, and terpenoid biomarker characteristics, in order to reconstruct the paleovegetation and reveal its influence on the formation of oil shale and coal. The K1ml2 is subdivided into lower, middle, and upper units. The studied oil shale samples from the lower and upper units display a high ash yield (Ad), low total organic carbon (TOC) and sulfur (S) contents, and limited hydrocarbon generation potential. The studied coal samples from the middle unit are characterized by low Ad, and high TOC and low S values, and show significant hydrocarbon generation potential. The paleovegetation during the formation of the lower unit was dominated by mire vegetation, such as shrubs (e.g., Lygodiaceae, Schizaeaceae), tree ferns (e.g., Dicksoniaceae/Cyatheaceae), and coniferous trees (e.g., Podocarpaceae). In the middle unit interval, the paleovegetation was represented by highland vegetation (Pinaceae and Araucariaceae) and peat-forming coniferous plants (e.g., Podocarpaceae, Cupressaceae/Taxodiaceae). Various vegetation, such as herbs (e.g., Osmundaceae), shrubs (e.g., Schizaeaceae), and coniferous trees (e.g., Podocarpaceae) was prosperous during the upper unit interval. Coniferous trees could provide abundant hydrogen-rich materials (e.g., resins) to the mire/lake, which may elevate the hydrogen content in peat/lake sediments, and finally result in higher hydrocarbon generation potential in the coal than in the oil shale. Therefore, the influence of paleovegetation on the formation of oil shale and coal should be fully considered when studying oil shale- and coal-bearing successions. The results also provide guidance for further exploration studies on oil shale and coal in northeast China.

Abstract:
Lavandula angustifolia Mill., known as one of the best essential oil-bearing plants, is an aromatic plant that is well cultivated in many Mediterranean regions due to its adaptability to variations in climatic and edaphic conditions. Therefore, its essential oil (EO) composition and its antimicrobial activity change as a consequence of abiotic and biotic factors. The chemical composition of L. angustifolia EO collected during four consecutive years of growth was one of the aims of this work. The volatile profile evidenced the prevalence of linalool and linalool acetate even though they switched their positions according to age. Plants in their first year were characterized by a high amount of sesquiterpene compounds (22.1% of the identified fraction). This percentage decreased during plant growth, not representing more than 5.3% in the fourth year. It is interesting to note that both the third- and fourth-year plants showed a content of monoterpenes that exceeded 90% of the total identified constituents. The EO extracted from the oldest plants evidenced higher activity on the studied strains, with more sensitivity on the Gram-positive ones. Tuscan lavender EO, especially that obtained from the four-year-old plants, is of great interest for its potential industrial applications and constitutes an example for the valorization of marginal Tuscan land and good-quality production.

Abstract:
Camellia is one of the four main oil-bearing trees along with olive, palm, and coconut in the world. Known as “Eastern Olive Oil,” camellia oil shares similar chemical composition with olive oil, with high amounts of oleic acid and linoleic acid and low saturated fats. Camellia was first exploited for edible oil in China more than 1000 years ago. Today, its oil serves as the main cooking oil in China’s southern provinces. Introduction of camellia oil into the Western countries was delayed until the recognition of its many health benefits. Although popularity for the oil has yet to grow outside of China, interest has emerged in commercial production of camellia oil in other countries in recent years. Unlike seed-oil plants that are grown on arable land, oil camellias normally grow on mountain slopes. This allows the new crop to take full usage of the marginal lands. To facilitate promoting this valuable crop as an alternative oil source and selecting promising cultivars for targeted habitats, this paper reviews the resources of oil camellias developed in China, use of by-products from oil-refining process, as well as the progress of developing camellias for oil production in China and other nations.

Abstract:
Abstract Rhododendron tomentosum Harmaja (formerly Ledum palustre L.) is a medicinal peat bog plant native to northern Europe, Asia and North America. This plant has a distinctive aroma thanks to the presence of essential oil, to which it also owes its anti-inflammatory, analgesic, antimicrobial and insecticidal properties. However, in Europe R. tomentosum is classified as an endangered species, mainly due to degradation of peatlands. In the present work, the micropropagation protocol for R. tomentosum was established for the first time, providing both an ex situ conservation tool and a means of continuous production of in vivo and in vitro plant material for further studies. R. tomentosum microshoots were initiated from leaf explants and further multiplied using Schenk-Hildebrandt (SH) medium supplemented with 9.84 μM 2iP and 1.00 μM TDZ. The shoots were elongated on the SH medium supplemented with 24.6 μM 2iP and subsequently rooted using the perlite substrate saturated with half-strength Woody Plant medium supplemented with 1.0% sucrose and 4.92 μM IBA. The regenerated plants were hardened on the phytohormone-free SH medium and acclimatized using 3:1:1 deacidified peat:perlite:gravel substrate. The identity of the mother plant was confirmed at morphological and molecular levels and Random Amplified Polymorphic DNA (RAPD) method was implemented to assess the genetic fidelity of the regenerants. The essential oil content of the maternal plant, in vitro shoots and the regenerants was determined by steam-distillation, and the obtained volatile fractions were analyzed by GC/MS.

Abstract:
SUMMARYWinter rapeseed was introduced into Greece a decade ago to provide oil for biodiesel. To identify agronomic traits affecting yield and quality, three hybrids and an inbred line were tested over two seasons (2005–2006 and 2006–2007) and four locations, in central and northern Greece, varying in pedo-climatic conditions. The large variations in seed yield, quality and agronomic traits were largely ascribed to location; in contrast, cultivar accounted for ⩽0·010 of the variation for many traits. Below 40°N, rapeseed is a risky crop; short season, high temperatures and low rainfall during reproductive growth diminished seed yield and oil content, increased oleic and erucic acid and minimized linolenic acid. A hybrid, Exact, with tall stature and large seeds was adaptive to such conditions. The most productive location had dense stands with tall plants bearing numerous pods on the main raceme. At the site with the coldest winter, plant density (PD) was lowest (ca. 30 plants/m2) but rapeseed compensated by producing large seeds, with high oil content and harvest index (HI). A biplot revealed that the hybrid Excalibur, outperforming the other cultivars for oil content in six out of eight trials, produced the highest and most stable oil yield. Combined data showed that seed yield and oil yield were positively correlated with PD, seed size and HI and negatively to the number of pods on branches and per plant. Large seeds had high seed oil content. Oleic acid was negatively correlated to linolenic acid concentration. High temperatures and low rainfall favoured oleic acid, which was positively associated with seed number per pod.

Methods. The object of the study was the flora and spatial localization of certain types of technical plants on the territory of Chechnya and adjacent territories. The material for the study was obtained as a result of observations in nature and collection of herbarium material during expeditionary researches from 2010 to 2017. Discussion. The article lists dyeing, essential oil-bearing, tannic, tar-bearing plants of the flora of Chechnya and adjacent territories. The main woodraw plants that provide valuable wood are also given special attention in the research; the qualitative properties of various woods and their intended use are briefly described. Are also descried many arboreal and herbaceous species which are widely used or are promising for tanning leather, fabrics, as well as species for obtaining essential oils and aromatic substances suitable for the use in liquor and vodka production, confectionery and other industries. Conclusion. The availability of large reserves of raw technical crops in the republics of the North Caucasus makes them very promising for industrial use. The study of the properties of biologically active substances, establishment of their structure, and creation of valuable herbal preparations on their basis is of great practical importance. On the territory of the Chechen Republic we have identified 157 types of technical plants belonging to 74 genera and 35 families. The problem of preserving the species diversity of valuable, economically useful, including technical plants in culture, becomes especially urgent in connection with the expansion of the use of new species as sources of biological substances.

Abstract:
Vegetable oil is extracted from oil rich seeds, such as soybeans. Genetic engineering of green plants to accumulate oil in vegetative tissue is a future source of oil that promises increased land productivity and the use of marginal lands. However, the low concentration of lipids in current engineered plant biomass samples makes the oil extraction process challenging and expensive. In this study, liquid hot water (LHW) pretreatment was investigated to enhance oil recovery from the solids and increase enzymatic hydrolysis efficiency of such feedstocks. Corn germ meal was chosen as a model feedstock representing lipid-producing energy crops. Germ meal was pretreated at 160 and 180 °C for 10 and 15 min at 20% w/w solids loading. Enzymatic hydrolysis on the pretreated solid was performed. After pretreatment, the oil concentration increased by 2.2 to 4.2 fold. The most severe pretreatment condition of LHW, at 180 °C for 15 min, gave the maximum oil concentration (9.7%, w/w), the highest triacylglycerol (TAG) content of the extracted oil (71.6%), and the highest conversions of glucose and xylose (99.0% and 32.8%, respectively). This study demonstrates that the optimal pretreatment condition for corn germ meal is 180 °C LHW for 15 min. Pretreatment improves lipids recovery from oil bearing biomass with little or no effect on the lipid profile.

Abstract:
Abstract Dracocephalum moldavica L. is an aromatic plant emitting intense lemon scent. The aboveground parts of the plants constitute raw material for medicine and food industry. In contrast to the comprehensively investigated trichomes, there are only few studies of the histochemical characteristics of the leaves of essential oil-bearing plants from the family Lamiaceae. The present study shows the micromorphology, anatomy, and histochemistry of the leaves of the analysed species. The research aimed to determine the location of essential oil and other specialised metabolites in leaf tissues. The investigations of fresh and fixed material were carried out with the use of light, fluorescence, and scanning electron microscopy. Additionally, the content and composition of essential oil in the leaves were determined with the GC/MS method. The leaf epidermis had non-glandular unbranched trichomes and three types of glandular trichomes: peltate as well as long and short capitate trichomes. The results of the histochemical assays showed positive reactions to lipids and to some secondary compounds such as essential oil, terpenes, phenolic compounds, and flavonoids in all types of the glandular and non-glandular trichomes. The same compounds were found in the epidermis cells of the leaves. The results of the present study indicate that the intense smell of the leaves is associated with emission of essential oil not only by the glandular and non-glandular trichomes but also by the leaf epidermis cells. The main components in the essential oil (0.10%) include geranial, neral, geraniol, nerol, and trans-myrtanol acetate. Since D. moldavica has been used as an adulterant of Melissa officinalis L., the anatomical traits of leaves and the essential oil composition in both species were compared in the study.

Gas has great potential to be converted into electrical energy. Indonesia has natural gas reserves up to 50 years in the future, but the optimization of the gas to be converted into electricity is low and unable to compete with coal. Gas is converted into electricity has low electrical efficiency (25%), and the raw materials are more expensive than coal. Steam from a lot of wasted gas turbine, thus the need for utilizing exhaust gas results from gas turbine units. Combined cycle technology (Gas and Steam Power Plant) be a solution to improve the efficiency of electricity. Among other Thermal Units, Steam Power Plant (Combined Cycle Power Plant) has a high electrical efficiency (45%). Weakness of the current Gas and Steam Power Plant peak burden still using fuel oil. Compressed Natural Gas (CNG) Technology may be used to accommodate the gas with little land use. CNG gas stored in the circumstances of great pressure up to 250 bar, in contrast to gas directly converted into electricity in a power plant only 27 bar pressure. Stored in CNG gas used as a fuel to replace load bearing peak. Lawyer System on CNG conversion as well as the power plant is generally only used compressed gas with greater pressure and a bit of land.

Abstract:
The effects of plant density on the growth and yield of winter oilseed rape (Brassica napus) were examined in a series of five multifactorial experiments at Rothamsted Experimental Station between 1984 and 1989. Plant densities, manipulated by changing the seed rate and row spacing, or because of overwinter losses, ranged from 13·5 to 372 plants/m2. Normalized yields for the multifactorial plots increased with densities up to 50–60 plants/m2. In very high density plots in 1987/88, yield decreased as density increased >150 plants/m2. Plants grown at high density had fewer pod-bearing branches per plant but produced more branches/m2. Branch dry matter (DM) per plant was decreased by 42%, the number of fertile pods per plant and pod DM/plant by 37%. There was no effect of density on the number or DM of pods/m2. Over 74% of the fertile pods were carried on the terminal and uppermost branches of plants grown at high density in 1987/88 compared with only 34% in plants grown at low density in 1988/89. Seed DM/plant decreased with increase in density but seed size (1000-seed weight) increased. There was no effect of density on seed glucosinolate or oil contents.

Abstract:
The recent decline in crude oil prices due to global competition and COVID-19-related demand issues has highlighted the need for the efficient operation of an oil and gas plant. One such avenue is accurate predictions about the remaining useful life (RUL) of components used in oil and gas plants. A tribosystem is comprised of the surfaces in relative motion and the lubricant between them. Lubricant oils play a significant role in keeping any tribosystem such as bearings and gears working smoothly over the lifetime of the oil and gas plant. The lubricant oil needs replenishment from time to time to avoid component breakdown due to the increased presence of wear debris and friction between the sliding surfaces of bearings and gears. Traditionally, this oil change is carried out at pre-determined times. This paper explored the possibilities of employing machine learning to predict early failure behavior in sensor-instrumented tribosystems. Specifically, deep learning and tribological data obtained from sensors deployed on the components can provide more accurate predictions about the RUL of the tribosystem. This automated maintenance can improve the overall efficiency of the component. The present study aimed to develop a deep learning-based digital twin for accurately predicting the RUL of a tribosystem comprised of a ball bearing-like test apparatus, a four-ball tester, and lubricant oil. A commercial lubricant used in the offshore oil and gas components was tested for its extreme pressure performance, and its welding load was measured using a four-ball tester. Three accelerated deterioration tests was carried out on the four-ball tester at a load below the welding load. Based on the wear scar measurements obtained from the experimental tests, the RUL data were used to train a multivariate convolutional neural network (CNN). The training accuracy of the model was above 99%, and the testing accuracy was above 95%. This work involved the model-free learning prediction of the remaining useful lifetime of ball bearing-type contacts as a function of key sensor input data (i.e., load, friction, temperature). This model can be deployed for in-field tribological machine elements to trigger automated maintenance without explicitly measuring the wear phenomenon.

Aim. To study accessions of new medicinal plants, to form and augment collections, to use valuable accessions of the gene pool in breeding and collections for educational and outreach activities. Results and Discussion. We present results of multi-year research work on creating collections of medicinal and essential-oil-bearing plants, their using in breeding, training and educational activities. The collection of the Botanical Nursery of the Experimental Station totals 990 samples belonging to 436 species of 254 genera of 69 families. The following genera are most fully represented: Mentha – 13 species (263 samples), Thymus L. – 11 species, Salvia L. – 6, Echinacea Moench – 6 (29 samples), etc. The collection consists of accessions from 22 countries: 605 from Ukraine, 29 from Russia, 22 from Germany, 12 from Bulgaria, 11 from the USA, 5 from France, etc. Training collections of mint and medicinal plants, trait collections of calendula, thyme, and echinacea and the basic collection of mint were formed and registered with the NCPGRU. Collections are dynamically being formed, and accessions of tree/shrub medicinal species belonging to the genera Sambucus L., Berberis L. and Crataegus L. are being studied. Selected accessions and sources of economically valuable traits are constantly involved in breeding. Ten new varieties of medicinal plants were originated from the gene pool accessions variety Yuvileina (2018) – from Dalmatian chamomile , variety Poltavka (2018) – from blessed milk thistle, variety Berezotitska Soniachna (2020) – from pot marigold, variety Struminka (2020) – from dyer's-madder. Acquisition companies in 14 regions of Ukraine resulted in gathering the gene pool accessions of valuable medicinal species for breeding and investigating: 720 seed samples, 62 planting material samples, 42 raw material samples and 691 herbarium specimens. Conclusions. The exploratory research at the Experimental Station of Medicinal Plants of IAEM NAAS allowed building up unique collections of medicinal and aromatic plants, accessions of which are used in breeding, training and educational activities, as well as to preserve the biodiversity of domestic and wild plants.
