- Abstract
This study investigated the in vitro antioxidant and biological properties of ethanol extracts obtained from the fruits of the highbush cranberry. The produced extracts exhibited a high content of polyphenols (1041.9 mg 100 g d.m.−1) and a high antioxidant activity (2271.2 mg TE g 100 d.m.−1 using the DPPH method, 1781.5 mg TE g 100 d.m.−1 using the ABTS method), as well as a substantial amount of vitamin C (418.2 mg 100 g d.m.−1). These extracts also demonstrated significant in vitro biological activity. Studies conducted on the Saccharomyces cerevisiae cellular model revealed the strong antioxidant effects of the extract, attributed to a significant reduction in the levels of reactive oxygen species (ROS) within the cells, confirming the utility of the extracts in mitigating oxidative stress. Moreover, inhibitory properties were demonstrated against factors activating metabolic processes characteristic of inflammatory conditions. It was observed that the cranberry extract inhibits the activity of cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2) non-selectively. Additionally, the extract was found to be a highly active inhibitor of acetylcholinesterase (AChE), potentially suggesting the applicability of this extract in the prevention of neurodegenerative diseases, including Alzheimer's disease.
