Influence of Ajuga turkestanica and Asparagus racemosus Phytoextracts on the Effectiveness of Aerobic–Anaerobic Training Regime

In this work, we study the effect of Asparagus racemosus (EAR) and Ajuga turkestanica (EAT) dry extracts at a dose of 100 mg/kg in comparison with a Rhaponticum carthamoides extract (ERC) on the effectiveness of an aerobic–anaerobic training regimen in female mice in a triple-weight loaded exhaustive swim test with a 10% load of body weight, as well as on the level of malondialdehyde and catalase activity in blood hemolysate, cardiac and skeletal striated muscle tissue, and liver homogenate. The results obtained indicate a reduced severity of lipid peroxidation under the influence of dry EAR and EAT extracts, thus pointing to the antioxidant activity of the extracts. In the conducted triple-weight loaded exhaustive swim test, a statistically significant increase in the duration of swimming No. 3 and the test index was noted in both groups compared to the control. Therefore, it can be concluded that the studied extracts have a positive effect on the first-phase recovery processes.

Natural Resources of Rhaponticum carthamoides in the Tarbagatai State National Nature Park

The study of medicinal plants and having a protected status is an urgent issue for the conservation of biodiversity in Kazakhstan. Rhaponticum carthamoides (Willd.) Ilijn is a medicinal plant, and its excessive harvesting and destruction of habitats, as well as its conservation status, are of concern. We conducted a study to assess the ecological characteristics of the habitat of the species in the Tarbagatai National Natural Park, calculate the amount of medicinal raw materials, calculate both aboveground and underground phytomass, and calculate biological and operational reserves. A map has been developed to show the distribution of the species and potential harvest sites. In addition, a correlation analysis was performed to understand how population size affects productivity. The results highlight the need for continuous monitoring and protection of endangered species. The conservation of Rhaponticum carthamoides in the Tarbagatai State National Nature Park is currently ensured by its protected status. However, the study emphasizes the importance of developing a sustainable use regime to effectively manage plant resources and ensure their preservation for future generations.

Phytoecdysteroids: Quantification in Selected Plant Species and Evaluation of Some Effects on Gastric Smooth Muscles.

Phytoecdysteroids (PEs) are naturally occurring steroid compounds, that have recently gained significant attention, due to their diverse biological activities and high therapeutic potential. The aim of the present study was to quantify some PEs including 20-hydroxyecdysterone (20-HE), ponasterone A (PA), and turkesterone (TU) in selected plant foods and Rhaponticum carthamoides extract. Furthermore, the effects of 20-HE, TU, and R. carthamoides extract, were investigated with in vitro methods using isolated smooth muscle tissues. The levels of 20-HE in the analyzed samples exhibited significant differences, with kaniwa seed extract containing the highest amount, followed by spinach leaf extract, quinoa seed extract, and asparagus stem extract. The in vitro analyses suggested that R. carthamoides extract exhibits dose-dependent cytotoxic effects on smooth muscle cells, with low doses promoting contraction and higher doses inducing relaxation. Additionally, the extract demonstrated a significant inhibitory effect on ACh-induced contractions, while 20-HE enhanced the contractile response. The current findings highlighted phytoecdysteroids' potential for modifying gastrointestinal motility.

Expression of Genes Related to Meat Productivity, Metabolic and Morphological Significance of Broiler Chickens with the Use of Nutritional Phytochemicals.

The study aimed to analyze gene expression linked to skeletal muscle growth and lipid metabolism in broiler chickens fed with plant extracts. Five groups of chickens were formed: four experimental groups and one control group. The diets of the experimental groups were supplemented with different plant extracts: chicory, St. John's wort, maral root, and creeping thyme, whereas the control group received feed without phytobiotic compounds. Weekly weighings were conducted (n = 36). The chickens were slaughtered at day 26 for tissue sampling of four birds from each group. Gene expression (MYOG, MSTN, FASN) related to muscle growth and fatty acid synthesis was analyzed using the β-actin ACTB gene as a reference. Blood samples were taken at day 35 for biochemical analysis and anatomical dissection was performed. The study revealed that using plant extracts from chicory, thyme, and maral root increased MYOG gene activity by 4.21, 7.45, and 8.93 times, respectively. T. serpyllum extract boosted the MSTN gene by 10.93 times, impacting muscle growth regulation. FASN gene expression for fatty acid synthesis increased significantly by 18.22-184.12 times with plant extracts. The best results regarding meat productivity of chickens were obtained when using R. carthamoides extract. The results of the study will serve as a basis for further development of a phytocomposition designed to increase the meat productivity of broiler chickens in the production of environmentally safe poultry products.

Modulating effects of fodder grasses extracts on antibiotic sensitivity and biofilm production in avian pathogenic Escherichia coli strains

Extracts of certain fodder grasses may be viewed as powerful agents against infections induced by avian pathogenic Escherichia coli strains. Here we demonstrated ability of Galega orientalis and Rhaponticum carthamoides extracts, alone or in combination with antibiotics, to inhibit growth, viability and biofilm formation in avian pathogenic Escherichia coli strains with different sensitivity to antibiotics and non-pathogenic laboratory strain E. coli BW25113 as well as its mutant derivatives. Modulation of motility and production of extracellular structures in the presence of the extracts correlated with their anti-biofilm effects. Interestingly, an increase in antibacterial action of kanamycin, streptomycin, ciprofloxacin, and cefotaxime on both biofilms and planktonic cultures of the studied strains was observed in the presence of the extracts, including antibiotic resistant APEC strain #45. The extracts alone showed weak prooxidant activity which could contribute to modification of redox-sensitive sites of various regulatory circuits, resulting to synergetic effects in combination with antibiotics.

INTRODUCTION TO IN VITRO CULTURE OF RHAPОNTICUM CARTHAMOIDES

The article presents the results of studies on the introduction into in vitro culture of the valuable medicinal plant Rhaponticum carthamoides, growing in the territory of the Kazakhstan Altai. R. carthamoides - or maral root is a source of various biologically active compounds (flavonoids, polysaccharides, saponins, cumanins). This species is of particular value as a producer of ultra-high quantities of ecdysteroids, which have a hepatoprotective and hypoglycemic effect, acting as adaptogens. Currently, natural reserves of this species are sharply reduced due to increasing demand and, as a consequence, lead to the depletion of natural populations. Modern biotechnology methods make it possible to develop highly effective approaches for the propagation and preservation of R. carthamoides for subsequent introduction and expansion of the range of fodder and medicinal crops that meet the needs of agriculture, medicine and the food industry. Seeds collected from their natural habitats were used as research material. A seed sterilization protocol has been developed; it has been established that to obtain aseptic seedlings it is necessary to use a multi-stage sterilization protocol using various sterilizing agents. Surface-sterilized seeds were placed on MS and MS media containing ½ mineral salts with different hormonal compositions. The results showed that the percentage of seed germination varied depending on the hormonal status of the environment and ranged from 42.9 to 85.5%. Thus, the lowest percentage of germination was noted on the B0 medium option (½ MS) - 42.9%. The highest percentage of germination was in seeds on the B3 medium option (MS + 3 mg/l BAP + 3 mg/l kinetin) - 85.5%.

Light-Emitting Diodes and Liquid System Affect the Caffeoylquinic Acid Derivative and Flavonoid Production and Shoot Growth of Rhaponticum carthamoides (Willd.) Iljin.

Plant in vitro cultures can be an effective tool in obtaining desired specialized metabolites. The purpose of this study was to evaluate the effect of light-emitting diodes (LEDs) on phenolic compounds in Rhaponticum carthamoides shoots cultured in vitro. R. carthamoides is an endemic and medicinal plant at risk of extinction due to the massive harvesting of its roots and rhizomes from the natural environment. The shoots were cultured on an agar-solidified and liquid-agitated Murashige and Skoog's medium supplemented with 0.1 mg/L of indole-3-acetic acid (IAA) and 0.5 mg/L of 6-benzyladenine (BA). The effect of the medium and different treatments of LED lights (blue (BL), red (RL), white (WL), and a combination of red and blue (R:BL; 7:3)) on R. carthamoides shoot growth and its biosynthetic potential was observed. Medium type and the duration of LED light exposure did not affect the proliferation rate of shoots, but they altered the shoot morphology and specialized metabolite accumulation. The liquid medium and BL light were the most beneficial for the caffeoylquinic acid derivatives (CQAs) production, shoot growth, and biomass increment. The liquid medium and BL light enhanced the content of the sum of all identified CQAs (6 mg/g DW) about three-fold compared to WL light and control, fluorescent lamps. HPLC-UV analysis confirmed that chlorogenic acid (5-CQA) was the primary compound in shoot extracts regardless of the type of culture and the light conditions (1.19-3.25 mg/g DW), with the highest level under R:BL light. BL and RL lights were equally effective. The abundant component was also 3,5-di-O-caffeoylquinic acid, accompanied by 4,5-di-O-caffeoylquinic acid, a tentatively identified dicaffeoylquinic acid derivative, and a tricaffeoylquinic acid derivative 2, the contents of which depended on the LED light conditions.

Ecdysterone and Turkesterone-Compounds with Prominent Potential in Sport and Healthy Nutrition.

The naturally occurring compounds ecdysterone and turkesterone, which are present in plants, including Rhaponticum carthamoides Willd. (Iljin), Spinacia oleracea L., Chenopodium quinoa Willd., and Ajuga turkestanica (Regel) Briq, are widely recognized due to their possible advantages for both general health and athletic performance. The current review investigates the beneficial biological effects of ecdysterone and turkesterone in nutrition, highlighting their roles not only in enhancing athletic performance but also in the management of various health problems. Plant-based diets, associated with various health benefits and environmental sustainability, often include sources rich in phytoecdysteroids. However, the therapeutic potential of phytoecdysteroid-rich extracts extends beyond sports nutrition, with promising applications in treating chronic fatigue, cardiovascular diseases, and neurodegenerative disorders.

Isoprenoids from Rhaponticum carthamoides (Willd.) Iljinand Rhaponticum serratuloides (Georgi.) Bobr

The article presents the results of a chemical study of Rhaponticum carthamoides (Willd.) Iljin. and Rhaponticum serratuloides (Georgi.) Bobr., which are of interest as sources of new adaptogenic, anabolic, and antiparasitic drugs; a method for complex chemical processing of the raw materials of the above-mentioned plants has been proposed. The structure of new sesquiterpene lactones raposerine, raserolide, 15-deacetylraposerine, and raserine has been isolated and established. The content of pharmacologically active ecdysterone in various organs of the studied Rhaponticum species is discussed according to the phenological phases of plant development. The antiparasitic, antiviral activity and cytotoxicity of the isolated compounds were determined.

Plant-Derived Extracts Plus Vitamin E and/or Aloe Vera Protect Against Intrinsic/Extrinsic Stressor in Human Skin: In Vitro and Clinical Evidence.

Humans are exposed to physical, biological, chemical, and psychological stressor throughout their life span. In recent years many medicinal plants have been shown to induce stress adapting and protective functions. Plant-derived extracts and vitamin E exhibit stress protection or resistance by normalizing cellular homeostasis and enhancing resistance to toxic stimuli to overcome cellular damage. Here we report the evaluation of a topical preparation (product test materials; PTM) containing an ingredient blend of Rhodiola Rosea, Eleutherococcus Senticosus (Siberian Ginseng), Rhaponticum Carthamoides, Inonotus Obliqus, and Slegainella Lepidophylla as the base formula and tested the addition of Lespedeza Capitata (leaf/stem) extract plus vitamin E and/or Aloe Vera to determine the induced protective functions in human skin when challenged with intrinsic and extrinsic stressors. The base topical preparation plus Lespedeza Capitata extract plus vitamin E or the base topical preparation plus vitamin E and Aloe Vera were assayed in vitro on (a) intrinsically stressed excised abdominoplasty skin, (b) full thickness (FT) skin equivalent models post-treated with a combination of ultra-violet (UV) B light (250 mJ/cm2) and diesel particular matter (DPM) (75 µg/mL) skin, for their effect on antioxidant, inflammation, and stress biomarker geners. Additionally, the bioadaptive activity of the PTMs was confirmed in providing resilience and protection against UV-induced erythema. For example, in a clinical study, daily topical application of the PTMs on the buttocks of 20 woman (18-78 years old), average age of 51.1 years, median body mass index (BMI) of 26.5 for 8 weeks followed by 2 minimal erythema dose (MED) of UVB exposure was accessed 24 hours after irradiation. Statistical analysis was performed by t-test and ANOVA, repectively. Pretreatment with the topical PTMs on intrsinically stressed skin significantly reduced the expression of the stress gene biomarkers, p53, pro-inflammatory cytokines Interleukin-1β (IL-1β) and Tumor Necrosis Factor-α (TNFα) and the pro-apoptotic BCL2 associated X, apoptosis regulator (BAX) values compared to controls. Topical application of the PTMs on Full Thickness (FT) human skin treated with UVB light and DPM significantly enhanced the stress response by activating heat shock transcription factor 4 (HSF4) and heat shock protein family B (small) member 1 (HSPB1) gene levels belonging to the heat shock protein (HSP) family by significantly increasing the expression of heme oxygenase 1 (HMOX1). At the same time, significantly reducing IL-1β levels were observed plus protection of skin cells from toxicity ocurred by significantly increasing the expression of B-cell lymphoma 2 (BCL2) (anti-apoptotic gene). In the clinical study, daily topical applications of the PTMs for 8 weeks followed by 2MED of UVB irradiation with clinical assessment 24 hours later revealed a significantly reduced intensity of erythema when compared to the buttock region treated with UVB alone. The PTMs containing adaptogen ingredients may confer stress resistance and induce stress protective responses against intrinsic as well as extrinsic stressors as demonstrated by the obtained in vitro and clinical evidence.

Phenolic Compounds and Antioxidant and Anti-Enzymatic Activities of Selected Adaptogenic Plants from South America, Asia, and Africa.

Despite the fact that there are many studies related to the adaptogenic and pro-healthy activities of plant-based compounds, there are some adaptogenic plants whose activities are not fully known, especially those coming from the wild regions of Asia, Africa, and South America. The aim of these studies was to examine the contents of non-nutritional compounds, such as polyphenols, flavonoids, and phenolic acids in ten adaptogenic species (Astragalus membranaceus (AM), Uncaria rhynchophylla (UR), Polygonum multiflorum (PM), Angelica sinensis (AS), Andrographis paniculatea (AP), Tinospora cordifolia (TC), Uncaria tomentosa (UT), Pfaffia paniculate (PP), Sutherlandia frutescens (SF), and Rhaponticum carthamoides (RC)). Considering biological activity, their antioxidant (DPPH, ABTS, FRAP, and ferrous-ion-chelating ability assays), anti-acetylcholinesterase, anti-hyaluronidase, and anti-tyrosinase activities were evaluated. The richest in polyphenols, flavonoids, and phenolic acids was UR (327.78 mg GAE/g, 230.13 mg QE/g, and 81.03 mg CA/g, respectively). The highest inhibitions of acetylcholinesterase, hyaluronidase, and tyrosinase were observed for TC, UR, and PM, respectively. In the case of antioxidant properties, extract from PM appeared to most strongly reduce DPPH, extract from UR inhibited ABTS, and extract from SF showed the best chelating properties. It should be noted that a particularly interesting plant was Ulcaria rhynchophylla. The results mean that there were compounds in UR with broad biological activities, and this species should be explored in more detail. Additionally, our results justify the traditional use of these species in the nutripharmacological or ethnopharmacological care systems of different regions.

Comparative analysis of genetic polymorphism in <i>Rhaponticum carthamoides</i> (Asteraceae) populations by ISSR markers in the Altai Republic

Background. Rhaponticum carthamoides (Willd.) Iljin (Asteraceae) is a rare species for the Altai Republic (AR). The purpose of this study was to characterize the genetic polymorphism of Rhaponticum carthamoides at the inter- and intrapopulation level in a comparative analysis for subsequent selection of seed samples from the genetically most heterogeneous natural populations of the AR for practical purposes. Materials and methods. The species was studied for ISSR variability in five habitats in the AR. DNA from dried leaves of R. carthamoides was isolated using the STAB method. For testing seventeen ISSR primers were used, seven of which were selected as most informative ones. Results and conclusion. The analysis showed that individual plants from five cenopopulations (CP) were distributed into three groups of similarity on the dendrogram. A separate clade was formed by plant samples from two CPs of the Katun Nature Reserve (KNR). Samples of one of those CPs grew on well-warmed southern slopes and exhibited a higher genetic heterogeneity than the others. The highest intrapopulation and interpopulation similarity in the distribution of DNA fragments was also found in two CPs from habitats with the smallest geographic distance from each other. Representatives of a separate population, least in size and number of individuals in the KNR, showed a high level of similarity in the distribution of DNA fragments. Significantly lower coefficients of genetic similarity with other CPs were found in plants from a small isolated CP from the Shavlinsky Protected Area. It can be assumed that one of the main reasons for the least genetic similarity of this population with others is its location in the immediate vicinity of the foothill at the pass to Achik (Ongudaysky District; absolute height: 2300 masl). This location can be a limiting factor for the exchange of genetic information with individuals from other populations.

Techno-economic and safety assessment of supercritical CO2 extraction of essential oils and extracts

Currently, products based on herbaceous plants are receiving global attention due to the significant rise in human awareness of environmental protection and well-being. These products contain compounds with valuable medicinal and nutritional effects. However, extracting these substances via conventional methods can be challenging concerning economic and environmental effects. Compared to conventional techniques, supercritical CO2 extraction is a clean technology that mitigates environmental issues and enhances extraction yields. This work focuses on developing a commercial-scale closed-cycle process using supercritical CO2 as a solvent with the possibility of varying feedstock material. The full process encompasses the raw material pre-treatment, the scCO2 extraction of compounds, and solvent recovery. This multiproduct processing unit includes three products: essential oil from garden angelica and extracts from roseroot and maral root. The process model was established using Aspen Plus®. Parallel to process design, safety was assessed by a hazard and operability study (HAZOP) to evaluate possible deviations during the operation. For assessing the feasibility of the process, a comprehensive techno-economic assessment was conducted. With this analysis, it can be seen that the designed production process is not only feasible but also economically profitable. For an annual production capacity of 13,240 kg, considering the three products, capital expenditure of 5.4 M€ was estimated. As to profitability, an internal rate of return of 40% and a payback time of 2.5 years resulted. In addition to economic benefits of the designed process, waste production was reduced by recycling used solvents and employing different approaches for mitigating greenhouse gas emissions.

Anti-Adipogenic Activity of Rhaponticum carthamoides and Its Secondary Metabolites

Besides their common use as an adaptogen, Rhaponticum carthamoides (Willd.) Iljin. rhizome and its root extract (RCE) are also reported to beneficially affect lipid metabolism. The main characteristic secondary metabolites of RCE are phytoecdysteroids. In order to determine an RCE’s phytoecdysteroid profile, a novel, sensitive, and robust high-performance thin-layer chromatography (HPTLC) method was developed and validated. Moreover, a comparative analysis was conducted to investigate the effects of RCE and its secondary metabolites on adipogenesis and adipolysis. The evaluation of the anti-adipogenic and lipolytic effects was performed using human Simpson–Golabi–Behmel syndrome cells, where lipid staining and measurement of released glycerol and free fatty acids were employed. The HPTLC method confirmed the presence of 20-hydroxyecdysone (20E), ponasterone A (PA), and turkesterone (TU) in RCE. The observed results revealed that RCE, 20E, and TU significantly reduced lipid accumulation in human adipocytes, demonstrating their anti-adipogenic activity. Moreover, RCE and 20E were found to effectively stimulate basal lipolysis. However, no significant effects were observed with PA and TU applications. Based on our findings, RCE and 20E affect both lipogenesis and lipolysis, while TU only restrains adipogenesis. These results are fundamental for further investigations.

More than 30 literary sources were analyzed as well. 6 species of the genus Rhapontiсum were identified within the territory of Kazakhstan, which can be classified according to the following ecological and high-altitude groups. The groups include species growing in the subalpine and alpine meadows of Altai such as Rhaponticum carthamoides (Wiild.) Iljin; plain species such as Rh. Serratuloides (Georgi) Bobr., Rh. Nitidum Fisch.; plants growing on rocky and gravelly slopes of the Western Tien Shan such as Rh. Karatavicum Regel et Shcmalh., Rh. aulieatense Iljin, Rh. namanganicum (Iljin) Dittrich. Medicinal species Rh. carthamoides, Rh. serratuloides and Rh. karatavicum were analyzed to research future prospects of their usage. The perspectives of plants having adaptogenic, psychostimulant, tonic, immunostimulating, anabolic, antibacterial, antioxidant, hemorheological, antiviral, cytotoxic, antiprotozoal properties have been noted and discussed to be used in the medicine, food industry, fodder production, landscape design, beekeeping areas.

Development and Validation of High-Performance Liquid Chromatography for Identification and Quantification of Phytoecdysteroids Ecdysterone and Turkesterone in Dietary Supplements

Phytoecdysteroids are a group of naturally occurring ecdysteroid hormones found in certain plant families and used for centuries for their adaptogenic, tonifying, and antioxidant properties. Ecdysterone and turkesterone are the dominant phytoecdysteroids found in the plant species Rhaponticum carthamoides Willd., Cyanotis arachnoidea C.B.Clarke and Ajuga turkestanica (Regel) Briq., and have been recognized for their adaptogenic potential and ability to enhance physical performance. However, over the past few years, supplementation with ecdysterone by professional athletes has raised some concerns about its safety and quality, leading to its inclusion in the World Anti-Doping Agency monitoring program. This study proposes a simple and reliable method for quality control of ecdysterone- and turkesterone-containing products using high-performance liquid chromatography (HPLC) analysis. The HPLC method is based on reversed-phase chromatography and gradient elution to achieve a superior separation of phytoecdysteroids. The method has been shown to qualify both phytoecdysteroids at low concentrations such as 10.98 μg/mL for ecdysterone and 11.43 μg/mL for turkesterone. This method could be successfully used in research programs and routine quality control of dietary supplements to ensure their safety in professional athletes’ nutrition.

Study of acute and chronic toxicity of feed additive based on vermiculture

The paper presents the results of study of the toxicity of a feed additive, which includes Leuzea safflower (Rhaponticum carthamoides) and protein obtained from vermiculture. The acute toxicity of the feed additive was studied in 31 SD white rats. It has been established that the acute oral toxicity of the feed additive is above 2500 mg/kg, which makes it possible to classify the feed additive as hazard class 3 and classify it as “moderately hazardous” according to GOST 12.1.007-76. The chronic toxicity of the feed additive was studied in 22 SD white rats. The feed additive was administered orally at a dose of 120 and 1200 mg/kg for 30 days. Long-term effects were assessed 14 days after the last introduction of the feed additive. To assess the toxic effects, the effect of the additive on the general condition of the animals, food and water intake was evaluated, blood and urine were analyzed. Complete blood count was carried out by standard methods with the determination of the following parameters: hematocrit, hemoglobin level, the number of erythrocytes, platelets, leukocytes, eosinophils, segmented neutrophils, lymphocytes and monocytes. The study of biochemical parameters of blood was carried out using standard kits for biochemical analysis. The following indicators were determined: ALT, total bilirubin, glucose, creatinine and urea. The urinalysis included the determination of the following indicators: density, leukocytes, nitrites, pH, erythrocytes, protein, glucose, ascorbic acid, ketones, urobilinogen, bilirubin. There was no statistically significant difference in blood and urine parameters between the animals of the control and experimental groups. A pathohistological examination of the stomach, liver, kidneys and heart was carried out, which showed the absence of a toxic effect of the feed additive. Local irritant action was studied in pathomorphological studies. It has been established that the feed additive does not have an irritating effect at the injection site. Thus, the feed additive can be used in feeding farm animals and birds at the recommended dose.

Adaptogens - use, history and future

Adaptogens are synthetic compounds or plant extracts that have the ability to increase the body's efficiency in the presence of stress stimuli. Extracts from ginseng, Eleutherococcus senticosus, Rhaponticum carthamoides, roseroot and chinensis are the best known plant adaptogens. The aim of this work is to assess the use of plant adaptogens in the past and present, and to outline the prospects for their future use. The use of natural adaptogens by humans has a rich history - they are used to treat many diseases, improve memory or reduce the effects of stress. Half a century ago, plant adaptogens were first used in competitive sports due to their effect on increasing the body's resistance to stress and improving physical endurance. Although many people now take plant adaptogens, human clinical trials are still very limited. Information obtained while writing this paper indicates that plant adaptogens may provide a number of benefits in the treatment of chronic fatigue, cognitive dysfunction and immune diseases.

ИСПОЛЬЗОВАНИЕ ПРЕПАРАТОВ НА ОСНОВЕ ЛЕВЗЕИ САФЛОРОВИДНОЙ В ЖИВОТНОВОДСТВЕ (ОБЗОР)

The purpose of the work is to summarize the results of our own research, as well as studies of domestic and foreign authors to study the composition, properties and issue of the use of drugs isolated on the basis of maral root in the process of growing farm animals. In connection with the adoption of a number of technical regulations, the requirements for the use of antibiotics and their lagging content in the final product have been tightened, and as a result, consumer demand for «environmental production» has increased. Literature analysis has shown that maral root is one of the most widely used medicinal herbs that is of interest to zootechnics because of its valuable anabolic, antioxidant, antistress, immunotropic and antimicrobial properties. Its popularity is caused by the increased content of biologically active substances and the wide range of effects of its drugs. Maral root has a long history of medical use, especially in infections. It has been proven that the toxicity of maral root is very low. The analysis found that current scientific research on the use of maral root in animal husbandry is limited, but can be used as a reference and rationale for use in animal husbandry to improve the well-being, productivity and immune status of various farm animal species.

Effect of Sucrose Concentration on Rhaponticum carthamoides (Willd.) Iljin Transformed Root Biomass, Caffeoylquinic Acid Derivative, and Flavonoid Production.

Rhaponticum carthamoides (Willd.) Iljin is a rare, pharmacopoeial, and medicinal plant, endemic to Siberia and endangered due to the massive collection of raw material from the natural habitat. The aim of the current study was to estimate the effect of sucrose concentration (0-7%) on R. carthamoides transformed root growth and on caffeoylquinic acid derivative (CQA) and flavonoid production. Sucrose in higher concentrations may induce osmotic stress and thus may affect secondary metabolism in plants. It was revealed that sucrose concentration influenced R. carthamoides transformed root biomass and modified the phenolic compound metabolic pathway. However, the dynamics of both processes varied significantly. The optimal sucrose level was different for biomass accumulation and the biosynthesis of specialized metabolite. The highest dry weight of roots was achieved for 7% sucrose (31.17 g L-1 of dry weight), while 1% sucrose was found to be optimal for phenolic acid and flavonoid production. Considering the dry weight increase and metabolite accumulation, 3% sucrose was revealed to give optimal yields of CQAs (511.1 mg L-1) and flavonoids (38.9 mg L-1). Chlorogenic acid, 3,5-, 4,5-di-O-caffeoylquinic acids, 1,4,5-O-tricaffeoylquinic acid, and a tentatively-identified tricaffeoylquinic acid derivative 1 were found to be the most abundant specialized metabolites among the identified CQAs. Our findings indicate that R. carthamoides transformed roots may be an efficient source of CQA derivatives, with valuable health-promoting activities.
