“…The content of heavy metals is below the standard values adopted by the US EPA (EPA, 2012 ). A comparative analysis of the composition of heavy metals shows that the peloids of Western Kazakhstan have mostly similar content of manganese, zinc, copper, lead, and cadmium with sapropels from Romanian saline lakes (Baricz et al, 2021 ), as well as zinc and lead with peloids from Ulcinj coast, Montenegro (Potpara et al, 2017 ), and San Diego de los Baños Thermal Center, Cuba (Suárez Muñoz et al, 2015 ). Comparing the available data from other countries, the mud of Southern and Western Kazakhstan has a low copper content; however, it has a high cadmium content.…”

In recent years, interest in natural therapeutic mud has been growing all over the world. This natural product has a positive therapeutic effect on the skin and has fewer side effects on the human body. There are more than 40 thousand salt lakes in Kazakhstan. Most of them have natural mud sources, the potential of which has not yet been fully explored. The review presents an analysis of the available information on the physical and chemical properties of the main sources of natural mud from salt lakes in Kazakhstan and Kazakh sanatoriums that use natural mud in the treatment. All available publications, presenting the systematic studies, were used for data analysis. A comparative analysis of the mineralization of water, brine, and silt in one reservoir shows that the mineralization of water is not always the least. The available data indicate a point and partial nature of peloid studies, e.g., inorganic composition of natural muds from Western and Southern Kazakhstan is well described in the literature. In turn, there is a lack of these data from Northern and Eastern Kazakhstan. Studies of peloids in these regions seem to be a promising direction of the future research for both local and world scientists. What is more, there is also a big gap in the analysis of organic matter of muds from the Kazakh lakes. Comparing the state of the art, i.e., the studies from other parts of Asia and Europe, the identification of the organic part of muds is another desirable direction as a potential source of biologically active compounds of natural origin.

“…To determine carotenoids and chlorophylls in medicinal plant raw materials use the method of liquid chromatography-mass spectrometry [24], high performance liquid chromatography (HPLC) [25]. For simultaneous detection of carotenoids and chlorophylls in sapropels use the method of high-performance liquid chromatography (HPLC) (HPLC-UV-VIS) [26], as well as the method of HPLC with photodiodes with UV -detection in the visible region and atmospheric pressure (High performance liquid chromatography with photodiode array UV -Vis detection and atmospheric pressure chemical ionization mass spectrometry) [27] and Raman spectroscopy [28].…”

For use in veterinary medicine for the treatment of the wound process and the prevention of mastitis, the composition and technology of an emulsion-based cream, conventionally called “Saprocream”, has been developed. Clinical trial of the drug “Saprocream” proved its effectiveness and safety for use in the healing of microtraumas, erosions and cracks (wounds) of the udders of cows. The aim of the research were was the standardization of the cream under the conventional name “Saprocream” for use in veterinary medicine as a wound healing agent, the development of methods of identification and quantification and their validation. Materials and methods. Test samples of emulsion cream type o / v, containing 15 % aqueous extract of sapropel (VES), 10 % oil extract of sapropel (OES), 6 % emulsifier No. 1, 1 % cetylstearyl alcohol, preservatives – 0.01 % nisin, 0.1 % euxil K 100 and purified water up to 100 g were made by phase inversion. The methods of pharmacopoeial articles of the European Pharmacopoeia of the 10th edition, SPhU 1.0, as well as industry standards were used to develop methods for identification and quantification of active pharmaceutical ingredients (API) in the developed cream and its standardization. Results. The chromatographic profile of the acetone extract from the cream coincides with the chromatographic profile of the reference solution ((PRS) β-carotene), which indicates the presence of substances of carotenoid structure. The absorption spectrum of hexane extraction from the cream in the range from 500 nm to 750 nm has a maximum absorption at a wavelength of 670±2 nm, which coincides with the maximum absorption of hexane solution OES, indicating the presence of chlorophyll. A method for quantifying the total mass fraction of humic acids (HA) has been developed and it has been established that the total mass fraction of HA in cream samples with sapropel extracts is 0.828 %. The results of the validation of the method show that there is a linear relationship between the concentration of the total mass fraction of HA and the mass of the AES sample with a correlation coefficient of 0.9981 (³ 0.9981). The developed technique is precise, because the value of the relative confidence interval is less than the critical value for the convergence of the results: D %=1.34≤1.60 and the criterion of insignificance of systematic error d=0.51 is fulfilled. Conclusions. An emulsion-based cream under the conventional name “Saprocream” has been standardized, methods for identification and quantification of active substances have been developed and validation of the developed methods for use in veterinary medicine as a wound-healing and anti-inflammatory agent has been carried out.

“…The chemical composition of natural muds, their physical properties, as well as the therapeutic effect are studied by researchers in different countries. A comprehensive physical and chemical study of mud was described, including the determination of pH, granulometry, chemical, and mineralogical composition, organic matter in Romania (Baricz et al, 2021), in Montenegro (Potpara et al, 2017), in Turkey (Odabasi et al, 2007), in Cuba (Martínez-Villegas et al, 2020. The factors influencing the formation of the chemical composition and genesis of silt mud include the salt composition of the brine of the reservoir, soil, and organic matter of plant and animal origin.…”
