Metabolomic Analysis and In Vitro Investigation of the Biological Properties of a By-Product Derived from Vicia faba

Chem Biodivers. 2023 Oct 25:e202301095. doi: 10.1002/cbdv.202301095. Online ahead of print.ABSTRACTBy-products from plant sources are recently regarded as a valuable source of bioactive compounds. In this regard, the present study aims to assess the bioactivities of the 70% MeOH extract obtained from Vicia faba peels and analyze its metabolomic profile. Acetylcholinesterase and carbohydrate metabolizing enzymes inhibitory activities of the plant extract were assayed using quantitative colorimetric tests. Antioxidant activity was estimated by DPPH assay, and cytotoxic activity was evaluated against normal fibroblast skin cells (1- BJ1). Ninety-one metabolites were tentatively identified using ultra-high-performance liquid chromatography (UHPLC) hyphenated with quadrupole-time-of-flight tandem mass spectrometry (QTOF-MS). Most of these compounds were described for the first time in the plant. In addition, catechin, rutin, quercitrin, and rhamnetin were isolated from the plant extract. The plant extract and the isolated compounds possessed no cytotoxic activity on (1- BJ1), while they exhibited anticholinesterase with the highest activity for 70% MeOH extract (IC50= 120.11mg/L), antioxidant potential with the highest activity for rutin (90.54±0.73%), and carbohydrate metabolizing inhibitory activities with the highest activity for rutin. These discoveries imply that V. faba peels might serve as an efficient antioxidant, exhibit anticholinesterase properties, and have the potent...
