The composition and content of starch largely determines quality of flour in breadmaking. The genotype and environmental conditions affect the quantity and qualitative composition of starch and the ratio of different types of starch granules in wheat endosperm. In this work, the qualitative and quantitative content of gluten, starch and starch fractions in the grain of wheat samples with hard and soft endosperm was studied to assess variability of traits. Wholemeal flour was separated into gluten, starch and dietary fiber by the \"plant on the table\" method. The isolated starch was separated into fractions A and B. Starch granules were examined using laser-scanning microscopy to determine their size. The analysis showed that the hard-grain variety Novosibirskaya 67 and the soft-grain variety Golubka could be the donors of high content of starch A. The hybrid lines SSL-2, SSL-2 and Rodina-M1 can be the donors of high content of starch B. For the studied samples, the proportion of small starch granules (<10 µm) was associated with grain endosperm structure.","PeriodicalId":9946,"journal":{"name":"chemistry of plant raw material","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139840979","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}

As a result of research, it has been established that during cavitation treatment, the chemical structure of sawdust is transformed, which ensures the production of hydrodynamically activated wood particles with a high content of reactive surface functional groups, which is caused by a change in the ligno-carbohydrate complex. It has been established that as a result of hydrodynamic activation, the amount of difficult-to-hydrolyze polysaccharides is reduced by 37%, while the proportions of easily hydrolyzable substances and substances of phenolic nature increase, respectively, by 12 and 25%. The transformation of the ligno-carbohydrate complex of wood particles during cavitation largely determines the change in the characteristics of their porous structure. An increase in the number of micropores by 1.5 times and large transport pores by 3 times during the cavitation process was established. The results obtained largely prove that the physical and chemical properties of hydrodynamically activated wood particles largely determine the possibility of obtaining non-toxic wood materials with high physical and mechanical properties without piezo-thermal effects.","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":"139324215","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}

Along with carbohydrates and proteins, HCCs are the most common compounds in the plant world and are found in almost all higher plants in free form, as part of esters and glycosides. Although the pharmacological activity of most HCCs has not been studied enough yet, however, its spectrum is quite wide. Many wild plants, which are currently used mainly in ethnoscience and traditional medicine, are cheap, affordable raw materials that are promising for introduction into the medical and pharmaceutical practice of our country as potential medicines. Therefore, the search for new plant species that are interesting for detailed study and the creation of modern medicines containing HCC on their basis is an scientific research area of current interest. The review is devoted to the study and systematization of paper and thin-layer chromatography methods used to determine the composition of HCC in plant raw materials growing on the territory of the Russian Federation as a potential raw material base of polyphenolic compounds. The review uses 80 sources of domestic scientific literature for the period from 2007 to 2022 inclusive, which show the results of the use of thin-layer (TLC) and paper (PC) chromatography for the study, identification and standardization of plant raw materials by the content of hydroxycinnamic acids (HCC).

For the first time, a water-soluble fraction of polysaccharides was isolated from radish seeds by sowing Margilan successive extraction after the extraction of proteins and polyphenols. Anion exchange chromatography and gel filtration were used to obtain homogeneous polysaccharides. The polysaccharide fraction was separated by ion-exchange chromatography, purified on a Sephadex G-100 column. As a result, two polysaccharides RSP1 and RSP2 were obtained. The monosaccharide composition of the isolated polysaccharides was established. Analysis of monosaccharide residues showed that the composition of the RSP1 polysaccharide is represented by monosaccharides in the following composition: rhamnose - 0.7%, ribose - 4.7%, arabinose - 55.6%, xylose - 1.5%, mannose - 3.7%, glucose - 5.1% and galactose - 28.7%.

From the obtained results, it can be seen that the RSP1 polysaccharide consists mainly of arabinose (55.6%) and galactose (28.7%) residues and belongs to the type of arabinogalactans, and the RSP2 polysaccharide mainly consists of glucose residues (64.9%) and galactose (18.4%).","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":"139324369","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}

A high saponins amount (6%) was detected in the aerial part during the flowering which decreased twice at the fruiting. The antioxidant activity and foaming index of the total ethanol extracts from the initial and deposited plant materials were determined. The maximum antioxidant activity (35.5%) and antiradical properties (IC50 1480) in vitro were found in extracts from the aerial part with the highest content of flavonoids and phenols.

For qualitative analysis of ascorbic acid and organic acids, extracts were obtained in three ways: in a flask in a water bath with a reverse refrigerator, in infusion mode, in decoction mode. The determination of organic acids was carried out using qualitative reactions, as well as by thin-layer chromatography and high-performance liquid chromatography. By the method of thin-layer chromatography in extracts from three samples of raw materials were identified oxalic, tartaric, citric, ascorbic and malic acids. The method of high-performance liquid chromatography confirmed the presence of five organic acids. The content of the sum of organic acids was: in fresh fruits – 6.52%, in dry fruits – 6.26%, in overwintered fruits – 6.35%. The content of ascorbic acid is 0.78%, 0.75% and 0.76%, respectively.
