Kombucha Fermentation Remodels the Phytochemical Composition of Gooseberry Juices and Reveals a Divergence Between Phenolic Abundance and HepG2 Cell Growth Inhibition

Kombucha fermentation can modify the phytochemical composition and biological properties of fruit-based beverages, although these changes may differ depending on the fermentation substrate. This study investigated the effects of 10-day kombucha fermentation using a symbiotic culture of bacteria and yeast (SCOBY) on red...

Polyphenolic Composition and Multifunctional Biological Properties of Raspberry Leaves: Variation Among Cultivar-Specific Samples

Despite increasing interest in raspberry leaves (Rubus idaeus L.) as a source of bioactive compounds, comparative information linking their phenolic composition to multiple biological properties remains limited. This study compared the polyphenolic profiles and biological properties of leaves from seven raspberry culti...

The Phenolic Composition of Centaurea cyanus L. Flower Extracts: Antioxidant, Antimicrobial, and Fibroblast Biocompatibility of a Phenolic-Rich Ethanolic Extract

The findings indicate that the phenolic-rich ethanolic extract demonstrated both antioxidant and antimicrobial activities while also being non-cytotoxic against fibroblasts within the tested concentration range; as such, it may be suitable for dermatological and cosmetic formulations.
