Exploring by-products as sources of bioactive compounds: LC-ESI-QTOF-MS profiling and bioactivity assessment of blood twig dogwood and cornelian cherry leaf extracts and fractions

Le résumé fourni par la source

The increasing incidence of chronic diseases, interest in bioactive compounds from agro-industrial by-products is increasing. This study explored the chemical profile and bioactivities of Cornus mas and Cornus sanguinea leaf extracts obtained through various extraction methods, especially focusing on the lesser-known C. sanguinea . The study assessed their anti-inflammatory properties (inhibition of NF-κB, nitric oxide reduction), antioxidant activity, and hypoglycaemic effects (inhibition of α-amylase and α-glucosidase). LC-ESI-QTOF-MS analysis identified phenolic acids, iridoids, and flavonoids as key constituents. Hydroalcoholic maceration of dried C. mas and ethanol maceration of fresh C. sanguinea were fractionated using XAD-16 resin. Bioactivity was tested on fractions and on three key compounds: sweroside, cornuside, and ellagic acid. Sweroside and cornuside inhibited highly NO production. Moreover, sweroside exhibited a notable α-glucosidase inhibition. These findings highlight the potential benefits of Cornus leaves, providing a basis to develop Cornus -based products for the prevention or treatments for type 2 diabetes and inflammation.
