“…Previously, UAE has also been effectively applied to the extraction of phenolics in several other food matrices such as black chokeberry [61], Laurus nobilis L. [62] and defatted hemp, flax and canola seed cakes [63] while SFE has been successfully used in hazelnut, coffee and grape wastes samples [64]. In fact, SFE, being a green process, has emerged in the last decade as one of the techniques of choice for the extraction and isolation of high-value natural products and phytochemicals, including polyphenols.…”

Polyphenols comprise a large family of naturally occurring secondary metabolites of plant-derived foods and are among the principal micronutrients associated with the health beneficial effects of our diet. Liquid chromatography coupled to mass spectrometry (LC-MS) and, in the last few years, high resolution mass spectrometry (LC-HRMS) is playing an important role in the research of polyphenols, not only for the determination of this family of compounds in food matrices, but also for the characterization and identification of new polyphenols, as well as the classification and authentication of natural extracts in the prevention of frauds. The purpose of this review is to describe recent advances in the LC-MS and LC-HRMS analysis and characterization of polyphenols in food focusing on the most relevant applications published in the last years. Trends regarding sample treatment, chromatographic separation, mass analyzers and chemometric approaches used in the determination and characterization of polyphenols will be addressed

“…Phenolic compounds are interesting in terms of a broad spectrum of biological properties, including antidiabetic, antioxidant, gastroprotecitve, anti-inflammatory, spasmolytic, antimicrobial, anticarcinogenic [ 22 , 23 ] but also antiseptic, disinfectant [ 24 ], hepato-protective, hypotensive and cardioprotective [ 25 ]. They have an influence on chronical and degenerative diseases [ 2 ] and different types of cancer [ 26 , 27 ]. The presence of phenolic compounds in plant materials determines their use in various areas of cosmetic, food and pharmaceutical industries.…”

“…The phenolic compounds are of a great interest for different institutions aimed at the applications of phenolics in food, cosmetics and pharmaceutical industries. Seeds, leaves, fruits and roots are the richest sources of not only polyphenols but also other groups of compounds, such as vitamins, fatty acids, triacylglycerols and others [ 1 , 2 ]. The efforts are made to obtain natural antioxidants and replace the synthetic ones that would be extremely beneficial from the viewpoint of health [ 3 , 4 ].…”

The Application of Supercritical Fluid Extraction in Phenolic Compounds Isolation from Natural Plant Materials

2018

View full text Add to dashboard Cite

The separation of phenolic compounds by supercritical fluid extraction has been widely studied throughout the last two decades. This is evidenced by a number of publications and articles. Supercritical fluid extraction (SFE) has become thus the effective method of separating the mentioned group of compounds. On the other hand, SFE is a beneficial approach in plant waste materials utilization and reduction of environmental burdens caused by the wastes. The aim of the study is to gather and systematize available information on the phenolic compounds separation that have been reported so far as well as to evaluate whether there is one optimal supercritical fluid extraction method for the phenolic compounds.

“…As stated before, the application of modern extraction techniques results in increased yields of different active compounds (Minjares-Fuentes et al, 2014;Manna et al, 2015;Ferrentino et al, 2018;Zachová et al, 2018;Pereira et al, 2019). The advantages of pressurized liquid extraction (super and sub-critical fluid extraction) are low processing temperature (removing the possibility of thermal degradation of phytochemicals), the ease of separation with no solvent residue in the recovered substance, and the minimization of undesirable oxidation reactions.…”

The growing demand for more sustainable, alternative processes leading to production of plant-derived preparations imposes the use of plants waste generated mainly by agri-food and pharmaceutical industries. These mostly unexploited but large quantities of plants waste also increase the interest in developing alternative approaches for sustainable production of therapeutic molecules. In order to reduce the amount of plant waste by further processing, different novel extraction techniques can be applied. Fruits and their industrial by-products are rich sources of different classes of compounds with therapeutic properties. The processed fruits waste can be reused and lead to novel pharmaceuticals, food supplements or functional foods. This review intends to briefly summarize recent aspects regarding the production of different active compounds from fruit by-products, and their therapeutic properties. The potential use of fruits by-products in different industries will be also discussed.
