The objective of the article is to investigate the chemical composition of roots methanolic extract and to evaluate the polyphenol content and antioxidant potential. Gas Chromatography-Mass Spectroscopy (GC-MS) and High-Performance Liquid Chromatography - Photo Diode Array (HPLC-PDA) techniques were used to characterize chemical composition of methanolic extract of roots. The GC-MS analysis extract resulted in the isolation of thirty-seven phytochemical constituents in methanol extracts. The root extracts were strongly characterized by 1-Propene, 2-nitro-3-(1-cyclooctenyl), (2E,4E)-N-Isobutyldodeca-2,4-dienamide, (+)- Seasmin and Paulowin. The phenolic composition of the root extract quantified by using HPLC revealed Ascorbic acid as most abundant polyphenol, followed by Gallic acid, Chlorogenic acid, Epigallocatechin gallate, Vanillic acid and p-hydroxybenzoic acid, while Caffeic acid was the recorded as least. In addition, root extract also showed the presence of antioxidant activity (DPPH Free radical scavenging, Metal Chelating and Ferric Reducing Antioxidant Activity) and polyphenol content (Total Phenol, Flavonoid, and Tannin Content).

Tyrosinase is a rate-limiting enzyme for melanogenesis and abnormal melanin production can be controlled by utilizing tyrosinase inhibitory substances. To develop potent and safe inhibitors of tyrosinase, complex tannins a narrowly distributed plant polyphenols were prepared from the fruit peel of Euryale ferox (EPTs) and then structurally characterized, as well as investigated for their inhibitory effects and the involved mechanisms against tyrosinase activity and melanogenesis. The structures of EPTs were established to consist of 63.

There is limited research on the influence of environmental variables on the interactions of biodegradable microplastics with chromium. This study reports the results of adsorption experiments with Cr and poly(lactic acid) (PLA) in synthetic aqueous solutions. It addresses the influence of the initial oxidation state, Cr(III) or Cr(VI), the effects of UV irradiation and the presence of organic matter.

Phenolic compounds (PC) were analyzed by UHPLC-ESI-QTOF-MS in two sorghum genotypes, harvested in two growing seasons (GS) at five distinct days after flowering (DAF) to evaluate how genotype/GS influences the PC synthesis and antioxidant capacity during grain growth. Total phenolic contents were strongly correlated with antioxidant capacity ( > 0.9, < 0.

The individual (poly)phenols of red wines cultivated in two different Western Balkan wine-growing regions were determined using the HPLC method, while the ABTS and DPPH tests were employed to investigate antioxidant activity. The reduction potential of antioxidants was determined by FRAP assay. Five distinct classes of phenolic compounds, including phenolic acids, flavan-3-ols, flavonols, stilbenes, and anthocyanins, were identified.
