Экстракцию корней женьшеня осуществляют водно-спиртовыми растворами или водой с последующим консервированием этиловым спиртом. При этом отмечается неполное извлечение биологически активных компонентов. Анализ химического состава корней женьшеня показал, что в них содержатся вещества различной полярности, поэтому целесообразно для лучшего извлечения экстрактивных веществ (ЭВ) проводить экстракцию этого лекарственного сырья в три этапа с использованием в качестве растворителей сжиженного диоксида углерода, этилового спирта и воды. Объектами исследования были экстракты, полученные из двух образцов измельченных корней женьшеня: из образца сырья 1 получены при последовательной экстракции СО2-экстракт из исходного сырья, спиртовой и водный экстракты; из образца сырья 2 – спиртовой экстракт из исходного сырья и водный экстракт из сырья, подвергнутого экстракции этиловым спиртом. Установлено, что последовательная экстракция сжиженным диоксидом углерода, этиловым спиртом и водой увеличивает выход ЭВ на 7% в сравнении с экстракцией только этиловым спиртом и водой. В составе СО2-экстракта корней женьшеня содержание токоферолов и других соединений фенольного ряда составляет 3,8%, каротиноидов 0,04%. Предварительная экстракция сжиженным диоксидом углерода корней женьшеня увеличивает выход органических кислот, флавоноидов и анионов солей в 5,8 раза; органических веществ, определенных методом ГЖХ, в 2,5 раза; моно-, ди- и полисахаридов в водном экстракте на 33,2% . В спиртовых экстрактах отмечено наибольшее содержание минеральных веществ: макроэлементов – магния, калия и фосфора; микроэлементов – марганца, железа, меди и йода. Общий выход сапонинов при последовательной экстракции корней женьшеня, включающей СО2-экстракцию, увеличивается на 9,7%. Результаты исследования подтверждают целесообразность разработки технологии комплексной переработки корней женьшеня, включающей применение в качестве растворителей сжиженного диоксида углерода, этилового спирта и воды. Extraction of ginseng roots is carried out with water-alcohol solutions or water, followed by preservation with ethyl alcohol. At the same time incomplete extraction of biologically active components is noted. Analysis of the chemical composition of ginseng roots shows that they contain substances of different polarities, so it is advisable to extract this medicinal raw material in three stages using liquefied carbon dioxide, ethyl alcohol and water as solvents for better extraction of extractive substances (ES). The objects of the study were extracts obtained from two samples of crushed ginseng roots: from a sample of raw materials 1, CO2-extract from the feedstock, alcohol and water extracts were obtained by sequential extraction; from a sample of raw materials 2 an alcohol extract from the feedstock and water aqueous extract from raw materials extracted with ethyl alcohol. It was found that sequential extraction with liquefied carbon dioxide, ethyl alcohol and water increases the ES yield by 7% in comparison with extraction with only ethyl alcohol and water. In the composition of the CO2-extract of ginseng roots, the content of tocopherols and other phenolic compounds is 3,8%, carotenoids 0,04%. Preliminary extraction of ginseng roots with liquefied carbon dioxide increases the yield of organic acids, flavonoids and anions of salts by 5,8 times; organic substances determined by the gas-liquid chromatography method by 2,5 times; mono-, di- and polysaccharides in an aqueous extract by 33,2%. The alcohol extracts have the highest content of minerals: macronutrients – magnesium, potassium and phosphorus; microelements – manganese, iron, copper and iodine. The total yield of saponins during sequential extraction of ginseng roots, including CO2-extraction, increases by 9,7%. The results of the study confirm the feasibility of developing a technology for complex processing of ginseng roots, including the use of liquefied carbon dioxide, ethyl alcohol and water as solvents.

AbstractHumans have dyed textiles and leather, colored food, and paint body parts using natural dyes throughout history. Natural dyes have suffered drastically due to recent socioeconomic changes and replacement with synthetic dye in the textile industry. Hence, it is urgent to study indigenous dye plants and dyeing craft in local communities to protect these resources' potential ecological, economic, and cultural values. In 11 Monpa villages of Mêdog County, South-east Tibet, China, we conducted field research to record the indigenous method of cloth dyeing using madder dye. An aqueous extract of the root of Rubia wallichiana is a traditional madder dye. In this study, we used traditional dye and ethyl alcohol extract of the residue of aqueous extract. Two fabrics were dyed with the extractions in the presence of one of the metallic mordants or biomordants. Pigment compounds from aqueous extraction of madder and ethyl alcohol extraction of recycled madder were evaluated using Phytochemical, UV–visible spectroscopy, and FTIR test. We carried out One-way ANOVA and Duncan's new multiple range method to analyze different dying approaches and conditions. The dyed fabrics were evaluated by indicators of color strength and fastness, including washing, rubbing, and perspiration. The findings revealed the potentiality of biomordants to improve the dyeing properties of madder. The dyeing properties of recycled madder were marginally better than traditional madder. The results revealed the feasibility of enhancing the dyeing property and reuse of the residue from madder dyeing. The improved dyeing and reuse of residue can improve local ecological, economic benefits, and cultural heritage while applying research findings for the subsequent commercialization of plant dyes.

The object of research in this work is the technology of pastille with the addition of multicomponent fruit and berry paste. Pastille are becoming more and more popular in the world for all segments of the population. Usually, the main ingredients for their manufacture are fruit raw materials, a structurant and egg white, therefore, the products contain practically no fat and have a low calorie content. It is proposed to replace 75 % of traditional applesauce in the recipe with a multicomponent fruit and berry paste made from apples, cranberries, hawthorn. It was found that such a composition makes it possible to obtain products with an increased content of pectin substances, ascorbic acid, polyphenols, including anthocyanins, catechins and flavonols. The work is aimed at studying the application of the principles of qualimetry to determine a complex indicator of the quality of pastille For this, the organoleptic and physicochemical indicators of the quality of the developed pastille were taken from previous studies and the chemical composition was determined and the content of biologically active substances was calculated relative to the average daily human need. The content of pectin substances in new products increases 1.7 times and satisfies the average daily human need by 18.2 %. The content of ascorbic acid is 4.2 times higher, which is 20.5 % of the average daily human need, and polyphenols 3.2 times higher – 579.0 %. The data obtained make it possible to consider the developed product functional. The next step was to determine the complex indicator of products by the qualimetric method. For a more complete disclosure of product properties, a structure of pastille quality indicators has been developed – a «tree of properties». Thus, the comprehensive assessment of the quality of the control sample corresponds to the indicator «good» (0.66), while the integrated assessment of pastille with multicomponent paste corresponds to the indicator «very good» (0.98). On the basis of organoleptic, physicochemical indicators and chemical composition of products, it was established that the indicator of a comprehensive assessment of the quality of a pastille with a multicomponent paste, taking into account all group indicators, is 48 % higher compared to the control.

Brown algae are a valuable source of a variety of biologically active compounds. Their accumulation is influenced by many environmental factors in which macrophytes grow. The purpose of this study is to carry out comparative studies of the general chemical composition of brown algae in the White and Yellow Seas to substantiate the possibility of their use as raw materials for obtaining new pharmaceutical substances. Using the proposed scheme, which involves sequential supercritical fluid, acid, alkaline and water extraction, it was possible to isolate various components of brown algae, including a protein-polysaccharide complex, which in the case of the species Laminaria digitata and Laminaria saccharina is more than 80% cellulose and squirrel. The data obtained by FTIR spectroscopy confirm the qualitative composition of the complexes and also indicate its purity. Significant differences were revealed in the chemical elemental and component composition, which are affected by the growing conditions of macrophytes. The resulting chemical compounds from brown algae biomass, in particular the protein-polysaccharide complex, have a high potential for obtaining new pharmacological preparations based on them for health protection purposes. Based on the previously obtained data, it can be assumed that this complex has a double activity – enterosorption and immunomodulatory.

Relevance. The search for new forms of herbal medicine is an important area of modern biotechnology, pharmacology and pharmacy. More and more attention is paid to the development of extracts from plant materials, since the extraction products provide the maximum content of biologically active substances, which increases the rationality of their use, due to the accuracy of dosing, the therapeutic effect is increased, the period of use increases and storage conditions are simplified. The extraction of the fruit mixture of Citrullus сolocynthis in the Soxhlet apparatus was modified by reducing the procedure time 5-10 times and improving the processing of raw materials by using a press at the same time and increasing the temperature, or even by modifying the apparatus. Objective: to study the composition of FA in an aqueous solution of the dry extract of Citrullus сolocynthis when modifying the extraction mixture in the Soxhlet apparatus by increasing the temperature and technological reduction of processing time. Materials and methods. We carried out the determination and comparison of the composition of FA’s by gas-liquid chromatography of all parts of the fruit of Citrullus сolocynthis and in an aqueous solution of its dry extract with various concentrations of the substance. Results. Chromatographic analysis showed that all parts of the fetus Citrullus colocynthis are promising sources of saturated and unsaturated FA. In all parts of the fruit of Citrullus colocynthis, linoleic acid prevails in quantitative content. The modification of the extraction of the mixture in the Soxhlet apparatus by increasing the temperature and technological reduction in the processing time of the raw materials led to the production of a substance with a new composition and FA content. The ratio of unsaturated / saturated FA in the resulting dry extract is 5 times greater than the similar ratio separately in seeds, pulp and shell. At the same time, the distribution of separate unsaturated and polyunsaturated FA’s in the dry extract solution is fairly uniform. The relative amount of linoleic FA in the dry extract was smaller, and the linolenic FA was greater than in the seeds and pulp of the fruit. Conclusions. Modifying the extraction of the mixture in the Soxhlet apparatus by increasing the temperature and technological reduction of the processing time did not lead to complete degreasing of the substrate and allowed to obtain a dry extract of Citrullus solvent with content of microdoses of the FA, their balanced (uniform) in amount, and predominance of 5 times the amount of unsaturated polyunsaturated FA over the amount of saturated. We assume that such a redistribution of FA, and especially their micro doses, can be the basis for creating medicines with more effective effects on the body.
