This study presents the metabolomic profiles of the four species ( Turcz., Pall., Fisch., and Purch.). The plant material was collected during two expeditions in the Russian Far East. Tandem mass spectrometry was used to detect target analytes. A total of 205 bioactive compounds (155 compounds from polyphenol group and 50 compounds from other chemical groups) were tentatively identified from the berries and extracts of the four species. For the first time, 29 chemical constituents from the polyphenol group were tentatively identified in the genus . The newly identified polyphenols include flavones, flavonols, flavan-3-ols, lignans, coumarins, stilbenes, and others. The other newly detected compounds in species are the naphthoquinone group (1,8-dihydroxy-anthraquinone, 1,3,6,8-tetrahydroxy-9(10H)-anthracenone, 8,8'-dihydroxy-2,2'-binaphthalene-1,1',4,4'-tetrone, etc.), polyhydroxycarboxylic acids, omega-3 fatty acids (stearidonic acid, linolenic acid), and others. Our results imply that species are rich in polyphenols, especially flavanols, anthocyanins, flavones, and flavan-3-ols. These results indicate the utility of species for the health and pharmaceutical industry.

Purpose Of Review: Berries are a great source of fiber, polyunsaturated fatty acids, and beneficial secondary metabolites (polyphenols). Various phytochemicals present in berries (glycosidic-linked flavonoids, anthocyanins, etc.) provide potential health benefits to consumers.

Background: The brain is a potential target for aluminium toxicity as it induces oxidative stress, strategies, rich in polyphenolic compound, containing flavonoid and possessing antioxidant property, found in natural plant products, to attenuate aluminium-induced impairments could provide a potential therapeutic intervention and protection for aluminium neurotoxicity.
Method: Forty adult rats weighing between 160 - 165g was used. The rats were divided into four groups (n = 10).

As a result of human activities, surface waters worldwide are experiencing increasing levels of eutrophication, leading to more frequent occurrences of microalgae, including harmful algal blooms. We aimed to investigate the impact of decomposing camelina straw on mixed phytoplankton communities from eutrophic water bodies, comparing it to the effects of barley straw. The research was carried out in 15 aquaria (five of each type - containing no straw, camelina straw, and barley straw).

Oxidative stress, associated with excessive production of reactive oxygen and nitrogen species (ROS, RNS), contributes to the development and progression of many ailments, such as aging, cardiovascular diseases, Alzheimer's disease, Parkinson's disease, diabetes, cancer, preeclampsia or multiple sclerosis. While phenols and polyphenols are the most studied antioxidants structurally similar compounds such as anilines or thiophenols are sporadically analyzed despite their radical scavenging potential. This work assesses the impact of structural features of phenols and thiophenols on their antioxidant activity.

Fenton reactions, commonly employed in environmental remediation, decompose H₂O₂ using Fe⁺ to generate free radicals. However, the efficiency is often limited by the slow conversion of Fe³⁺ to Fe⁺. In this study, we synthesize zero-valent iron nanoparticles (nZVI) via a green, plant extract-mediated reduction method, resulting in nZVI coated with a reductive polyphenolic layer that enhances Fe³⁺/Fe⁺ cycling.
