“…In most cases, solid-liquid extraction can be advantageously used for the recovery of natural compounds from untreated or pretreated biomass materials [10][11][12][13]. A large number of studies indicate that the extraction yields and the properties of the recovered compounds are significantly dependent on the structural and compositional features of the plant matrix, the type of compounds and the strength with which they are bound to the matrix [14][15][16]. As a result, a deep knowledge of the characteristics of the system under investigation is required.…”

Water–Organic Solvent Extraction of Phenolic Antioxidants from Brewers’ Spent Grain

2019

Brewers’ spent grain (BSG) is the most abundant by-product of the brewing process. BSG is currently disposed of or used as a supplement for animal feed, although it contains significant amounts of bioactive compounds of great interest to the pharmaceutical, cosmetic and food sectors. In this study we investigate the feasibility of using a simple solvent extraction procedure to recover phenolic antioxidants from BSG. Acetone–water and ethanol–water mixtures were used as extraction solvents. Phenolic extracts obtained by treatment of BSG with the two solvent systems were characterized in terms of total phenolics and antioxidant activity. For both systems, the extraction yield was maximum at 60% (v/v) organic solvent concentration. At all solvent compositions, mixtures containing acetone provided higher extraction yields. As suggested by the strong correlation between the antioxidant activity of BSG extracts and their phenolic content, the antioxidant capacity of the extracts can be mainly attributed to polyphenols. Overall, the obtained results strongly support the exploitation of BSG as a source of phenolic antioxidants and the possibility of recovering them by a mild and green extraction process.

Tannins are phenolic compounds with considerable abundance in nature. They have attracted significant attention lately owing to their huge variety of potential applications. Accordingly, the tannin-related activity in terms of research has undergone a great boost, especially as green feedstock for materials in several fields. Nevertheless, the extraction process remains as the main bottleneck for their valorization, due to their heterogeneous nature. In the present review, a comprehensive study of the main types of tannins extraction techniques was carried out based on the works from the last 20 years. The literature review was carried through analysis of an initial sample of works followed by snowballing process, obtaining the main extraction parameters of each method. Thereby, the different tannins extraction methods were assessed and their major strengths and weaknesses elucidated. Moreover, a direct comparison between the different techniques was done, leading to the main prospectives for the efficient and clean tannins extraction and production.

Determination of xanthones in plants and the nutrient medium under in vitro cultivation conditions

et al. 2018

View full text Add to dashboard Cite

In recent years, xanthones have received considerable attention from scientists due to their biological activity: anticarcinogenic, antiviral, antibacterial, antioxidant, anti-inflammatory and other properties.Therefore they are useful for prevention and treatment of different diseases:cancer, Alzheimer's and Parkinson's disease, cardiovascular disorders, diabetes, etc. Extracts of different species of plants containing xanthones are components of chemotherapeutic and other medical drugs. In order to find the most sensitive and environmentally safe method of quantitative determination of xanthones in the plant material and the nutrient medium, known methods were tested and selected for the prototype Vyisochina G. I. et al., 2011 method, which uses ethanol as an extractor. As the plant material we used plants of different species that were grown under in vitro cultivation conditions on the agarized nutrient medium. This agarized nutrient medium was also used for the xanthone content analysis. Based on the performed research, modifications of the method for determining the content of xanthones were adapted to the in vitro conditions, which detail the specificity of extraction and quantitative calculation of the xanthone content in plant explants. Our own method of determination of these compounds in the agarized nutrient medium was developed as well. The method, that we proposed, will significantly speed up the process of xanthone detecting and will also increase their yield in biotechnological processes for obtaining the pharmacologically valuable secondary metabolites of phenolic nature.
