The research was carried out on forested pasture areas of the Neftekumsky district of the Stavropol Territory. The basis of the research was the laboratory-field method. The twig-leaf and herbaceous phytomass of forest pastures, in accordance with its chemical indicators of organic matter content, meets zootechnical requirements. The maximum protein content is observed in spring in the woody greenery of Ulmus pumila (at the level of 18.19%) and decreases in autumn (17.4%). In addition, it was found that the twig-leaf mass of Ulmus pumila has a relatively high feed value (0.68 f.u., 8.5 Mj, digestible protein 62.67 g/kg) than herbaceous species and is a large reserve in forest pastures during drought or absence of herbaceous vegetation before the establishment of snow cover. As a result of the research, it was also found that during the dry period (summer) in the grass-grass and grass-grass phytocenoses, there is a low protein content (less than 10%) and a high fiber content (34.0–35.13%). The nutritional value of plants in general on man–made forest pastures is 0.25–0.68 fodder units, while 1 kg of feed contains 31.0–78.48 g of digestible protein. The fat content in the analyzed plants in the territory under consideration is small (1.10–4.23%), and the content of nitrogen-free extractives is quite high (30.44–65.2%) regardless of the season of the year. According to the content of macronutrients, a deficiency of phosphorus (P) was detected according to the norms. Accordingly, with constant grazing of animals in these areas, it is necessary to additionally include feed additives containing this element in the diet for the prevention of deficiency and diseases.","PeriodicalId":9946,"journal":{"name":"chemistry of plant raw material","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139324091","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The difficulty of obtaining MCC from vegetable raw materials is that, in addition to cellulose, it contains in its composition such compounds as lignin, hemicelluloses, various extractive substances and an insignificant percentage of minerals. When grinding plant fibers in an aqueous medium, both a purely mechanical process of changing the size and shape of fibers and a colloidal chemical process called fiber hydration occurs. Mechanical phenomena are expressed in the shortening of fibers, their longitudinal splitting into fibrils, an increase in the outer surface and the number of free hydroxyl groups on their surface. The term hydration refers to colloidal chemical phenomena that begin with the swelling of hydrophilic plant fibers. The paper considers methods for obtaining microcrystalline cellulose and factors influencing the development of a fibrous suspension isolated from coniferous wood species in a grinding plant with inertial bodies. Multiphysical models of the flow of fibrous suspension in the installation are constructed. A study of the effect of grinding a fibrous suspension on the process of obtaining fine cellulose was carried out. The indicators of the finished product are given. The change in the degree of polymerization of cellulose that has previously passed the grinding stage, with different degrees of grinding according to the Shopper-Rigler, is analyzed. Data on cost reduction and resource savings (acid concentration, temperature and processing time) in the process of obtaining fine cellulose are presented.","PeriodicalId":9946,"journal":{"name":"chemistry of plant raw material","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139324271","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Phenotypic factors (altitude above sea level, soil composition, number of sunny days, precipitation volume, humidity, average daytime temperature, etc.) affected the vitamin composition of milk thistle fruits growing in natural conditions. High-performance liquid chromatography in gradient elution mode was used to determine water-soluble vitamins in milk thistle fruit samples. Nine water-soluble vitamins in milk thistle fruits (ascorbic acid, vitamins B and PP) have been identified and quantified. The variability of the content of water-soluble vitamins in the fruits of wild milk thistle, depending on the growing conditions, has been established. Statistical analysis of the data array on vitamin composition showed the presence of not only significant symbate and asymmetric correlations of the type Y=aX+b (pair correlation coefficient |R|≥0.55), but also close natural correlations (|R|≥0.80) between the content of certain vitamins and individual phenotypic factors.","PeriodicalId":9946,"journal":{"name":"chemistry of plant raw material","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139324188","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Leaf extracts have antioxidant, anti-inflammatory, antibacterial, antiviral, adaptogenic and immunostimulatory properties due to the complex of biologically active substances (BAS) (tannins, organic acids and flavonoids), which confirms their value as MPRM for the development of herbal medicines (HMP) on their basis. The aim of the work was to study the composition of organic acids (including amino acids) of sea buckthorn leaves of various phenological phases of the harvest. The object of the study is the dried leaves of sea buckthorn of three phenological phases of plant life (I – the phase of fruit set, II – the phase of single fruit ripening, III – the phase of mass ripening of fruits) collected on the territory of the Voronezh region and dried leaves of sea buckthorn in 2021. The objectives of the study included a comprehensive study of the composition of the fraction of organic acids in leaves (free and bound) using the methods of chemical and physicochemical analysis. The data obtained showed that, in general, the qualitative composition of the BAS of the group of acids of the studied leaf phenophases is similar to each other, but differs quantitatively. For the harvesting of this medicinal product on an industrial scale, from the point of view of the content of the total organic acids, the harvesting phase can be recommended, since early deleafing can lead to a decrease in the accumulation of valuable BAS groups in fruits – the source of the pharmacopoeial preparation «Oil of Hippophaës».","PeriodicalId":9946,"journal":{"name":"chemistry of plant raw material","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139324330","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The predominant component of external birch bark extracts is pentacyclic triterpene alcohol - betulin. Allobetulin (19,28-epoxy-oleanan-3-ol) is an isomer of betulin and belongs to the pentacyclic triterpenoids of the oleanane types. Allobetulin and its derivatives are non-toxic compounds and they have antiviral, antimicrobial and antitumor activities. A new one-step method for producing allobetulin directly from birch bark by combining the stages of betulin extraction with ethanol and its isomerization into allobetulin in the presence of phosphoric acid catalyst was developed. The effect of the duration of birch bark treatment with ethanol and H3PO4 content on the yield of allobetulin was esteblished. The highest yield of crude allobetulin (35% by weight of a.s.b.) is achieved at a process duration of 8 hours in the presence of 5% H3PO4 and also at a duration of 15 hours in the presence of 3% H3PO4. The yield of recrystallized allobetulin is about 22% of the weight of absolutely dry birch bark. The composition of the allobetulin sample after recrystallization from isopropanol was confirmed by elemental analysis and its structure by – IRS and 1H NMR methods. The antioxidant properties of allobetulin were established in vivo and in vitro experiments.","PeriodicalId":9946,"journal":{"name":"chemistry of plant raw material","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139324422","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
