Academic literature on the topic 'Medicinal plants Northern Territory Composition'

Aromatic and Medicinal Plants (AMP) represent a large part of biodiversity. However, in the absence of a detailed record of this diversity, research and AMP development projects are generally limited to a small portion of ethnobotanical heritage. To guide prospection, exploitation and conservation studies of the existing potential, a comprehensive evaluation of the natural diversity of AMP is required. The western Rif region in northern Morocco, which area represents less than 1% of national territory, is home to about 50% of the Moroccan floristic richness (2053 species and infraspecific taxa). This heritage includes 630 taxa from which only 23 are currently exploited and merely 57% are recognized by ethno-botanists. Among these assets, a list is drawn up containing 106 taxa with a special conservation status (very rare or rare taxa, and / or endemic and / or threatened) and some of which are widely exploited. From a phytosociological point of view and based on an available database of 449 floristic samples, natural forest stands and matorrals contain about 27% of all MAP of the study area. These AMP organize almost half the floristic composition of sclerophyllous forests (oleaster, kermes oak and cork oak forest) and about a third of the richness of each of the other groups analyzed (thermophilic formations, pure fir, limestone mountains forest, calcifuges deciduous, maritime pine, matorrals). Mountain groups are the richest in exclusive, endemic, rare and endangered AMP.

Introduction. Orthilia secunda (L.) House is a perennial herb that grows in Europe, Siberia, Asia Minor and Central Asia. The herb of Orthilia secunda is actively used in folk medicine as a diuretic, wound-healing and anti-inflammatory agent. From literary sources it is known that this medicinal plant raw material (PRM) contains flavonoids, tannins, organic acids, vitamins, as well as simple phenols and their derivatives (arbutin and hydroquinone). The presence of arbutin is responsible for the plant's high antioxidant and anti-inflammatory properties. But the use of Orthilia secunda in official medicine is limited due to the lack of complete information on the chemical composition and criteria for standardization of this type of medicinal product.Aim. Identification and quantification of arbutin by chromatographic methods in Orthilia secunda (L.) House, harvested in various phytocenotic zones.Materials and methods. The investigated medicinal plant material – the herb of Orthilia secunda – was harvested in various phytocenotic zones: in July 2018, harvesting was carried out in the northern part of Kazakhstan (Kokshetau district), in July-August 2019 in the Perm Territory and in the Tyumen Region. Preliminary identification of arbutin and related phenols – gallic acid and hydroquinone – was carried out by high performance thin layer chromatography (HPTLC) on a CAMAG instrument with a UV cabinet (Merck HPTLC silica gel 60 F154 plates, 20 × 10), semi-automatic Linomat 5 applicator (sample application). Elution of the plates was performed in a CAMAG Automatic Developing Chamber (ADC2). Image fixation was performed on a CAMAG Scanner 3 spectrodensitometer. The quantitative determination of arbutin was carried out by the method of highperformance liquid chromatography, which was carried out on a Prominence LC-20 device (Shimadzu, Japan) according to the validated method described in the European Pharmacopoeia 10.0. Diode array detector SPD-M20A, column Intersil C18 column (250–4.6 mm, 5 μm) (Phenomenex, USA). The results were processed using the LabSolution software. The identification and quantification of arbutin was carried out in comparison with a standard solution containing a reference sample (RS) of arbutin (C = 0,025 mg/ml) and RS of hydroquinone (C = 0,0125 mg/ml).Results and discussion. HPTLC analysis made it possible to detect arbutin and gallic acid – the main product of hydrolytic degradation/ precursor of the biosynthesis of tannins of the hydrolysable group – in the herb of Orthilia secunda from different places of growth. HPLC analysis demonstrates a different chromatographic profile of Orthilia herb harvested in different phytocenotic zones. However, in all studied objects, the absence of hydroquinone and the presence of substances that can presumably be attributed to its derivatives were confirmed, which is confirmed by the visual similarity of the spectra of these compounds and the proximity of the extrema. It was found that arbutin does not belong to the marker (majority) compounds of Orthilia. Its content is low and reaches a maximum (about 0,021 %) in the herb of Orthilia secunda growing on the territory of Kazakhstan, while in the herb of Orthilia harvested in the Perm Territory arbutin was not identified. From the data obtained, it follows that the greatest accumulation of arbutin occurs in areas with a warmer and drier climate (northern part of Kazakhstan).Conclusion. HPTLC analysis of the herb Orthilia secunda allowed the identification of arbutin and gallic acid (the main precursor of tannins of the hydrolysable group). The results of HPLC analysis of Orthilia herb harvested in various phytocenotic zones suggest quantitative differences in the content of arbutin depending on the region of growth. From the experimental data, it follows that Orthilia growing in the northern part of Kazakhstan accumulates the maximum (0,021%) amount of arbutin, in comparison with the samples harvested in the Tyumen region and the Perm region. At the same time, Orthilia harvested in the Perm Territory does not accumulate arbutin. The presence of hydroquinone has not been confirmed (by HPTLC and HPLC methods); therefore, it is not justified to talk about the hydrolytic cleavage of arbutin in the process of biosynthesis or drying. However, in all studied objects there are peaks of substances with spectral characteristics like hydroquinone, which makes it possible to assume the presence of its derivatives. Therefore, it is not advisable to position arbutin as a marker compound of Orthilia secunda harvested on the territory of the Russian Federation, and to standardize raw materials for this compound.

The following paper considers aspects of systematic and ecological structure of the weed medicinal plants growing in the biosphere reserve Pribuzhskoye Polesye. The studied weed plants of the region are considered to be used in pharmacology and medicine. Therefore, a detailed study of environmental groups and economic importance of commensal medicinal plants can serve as a basis for new trends development in resource studies of medicinal plants. The paper identifies diagnostic signs, as well as similarities and differences of morphometric evidence. The collection of field data was carried out by reconnaissance of the terrain. The study shows that the territory of the biosphere reserve Pribuzhskoye Polesye is characterized by a rich species composition of synanthropic weed medicinal plants of 57 species growing in different habitats that can be used for the treatment of diseases of the gastrointestinal tract, circulatory system and respiratory system. It is necessary to use weed plants for medicinal purposes to increase the base of receiving biologically active materials of plants.

The peculiarity of the geographical location of the Pereyaslav Region, the existence of dense river nets (the Dnieper River, the Trubizh River, the Alta River, the Supiy River, etc.) and the diversity of landscapes led to the formation of the region rich in plant species. However, the vegetation cover of the region has been significantly transformed as a result of the construction of a hydroelectric power plant on the Dnieper River and the creation of the Kaniv Reservoir. The purpose of the article is to carry out a systematic, biomorphological and ecological analysis of the composition of wild medicinal plants of the Pereyaslav region. The research was conducted during 2018-2019 years on the territory of the Pereyaslav Region. The object of the study is the flora of wild medicinal plants of the Pereyaslav Region. The study was performed by means of the route, stationary and semi-stationary methods. During the field surveys (geobotanical descriptions) of the studied territory, the flora was described, species and families of the plants were determined, their location and ecological conditions of growth, life form, etc. were noted. As a result of the critical inventory of the species composition of the Pereyaslav flora, the systematic composition of wild herbs and medicinal plants of the region was first developed (582 species), consisting of 106 families and 360 species, among which there are vascular plants (Lycopodiophyta, Equisetophyta, Polypodiophyta) – 15 species, Pinophyta – 3 species, Magnoliophyta – 567 species. The biomorphological analysis of wild herbs and medicinal plants of the Pereyaslav Region was performed and it was established that the vast majority of species belong to hemicryptophytes (316 species). It was found that in the studied territory the diversity of wild medicinal plants is represented by trees (27 species), shrubs (28 species), subshrubs (10 species), perennial herbaceous plants (387 species), biennial plants (46 species) and annual plants (84 species). It has been established that the ecological-coenotic nature of valuable species of plants in the study consists of forest (170 species), meadow (145 species), meadow-steppe (114 species), synanthropic phytocenoses consist of 95 species and wetland ecotopes – 58 species.

The article presents research data on studies of the current state of the species composition of medicinal plants growing in the south of the Far East on the territory of the forest area of FSBEI HP «Primorskaya State Agricultural Academy» in mountain cedar-latitudinal forests. Biological harvest, production harvest is calculated, size of usage is established and period of restoration of medicinal plants is determined. The work shows how much raw materials can be harvested during one-time operation of thickets. Analysis was carried out, which made it possible to determine the main species composition of plants in hazelnut cedar with linden and oak and in different-shellfish cedar with yellow birch, to distinguish from them the types of medicinal plants characteristic of these types of forest. It was established that 18 types of medicinal plants are promising for volumetric harvesting of above-ground and underground organs. The yield of the remaining species is insignificant and is possible only with the observance of the rules for harvesting during the take-away measures to increase their phytomass.

A number of valuable medicinal plants will grow in the Trans-Baikal Territory, but there is not enough information on the content of chemical elements in them, including vital and toxic ones. The aim of the work was to study the content of chemical elements in medicinal plants in one of the districts of the Trans-Baikal Territory. The concentration of 43 chemical elements in the roots of Saposhnikovia divaricata, Paeonia lactiflora and Phlojodicarpus sibiricus growing in the Nerchinsk steppe (Eastern Transbaikalia) was studied. Soil samples were taken at the plant growth sites to analyze the granulometric composition, pH, content of mobile forms N, P, K, and a number of trace elements. The ecological conditions of the habitat were noted: the height above sea level, the exposure and steepness of the slope, the type and floral composition of the plant community. The roots of the plants, after being released from the ground, were placed in cloth bags and dried. At each site, a mixed sample of 5–15 roots was taken, depending on the weight of the root. Chemical analysis of the soil and plants was carried out in certified laboratories in Moscow. Kostroma and Khabarovsk. In the roots of plants, the concentration of Ti, Cr, Sc, La, Ce, Li, Nb and a number of other elements was found to be high relative to the Clark of terrestrial plants, and the content of Mn, Tl, Se, Cd and other elements was relatively low. The concentration of toxic elements Pb, Cd and Hg did not exceed the MPC in the medicinal raw materials, and the accumulation of As exceeded the MPC in the medicinal raw materials by 4–6 times. The studies conducted in this area were conducted for the first time, they allow us to judge the quality of medicinal raw materials, and in the future, to compare the results with other areas of plant growth.
