Research on the Antioxidant and Anti-Inflammatory Effects of Hawthorn Polyphenols

Abstract

Hawthorn (Crataegus pinnatifida) polyphenols are important natural plant chemicals with significant antioxidant and anti-inflammatory effects. This study aims to systematically explore the chemical components of hawthorn polyphenols and their impact on oxidative stress and inflammatory responses. Hawthorn polyphenols mainly include hawthorn acid, flavonoids, and tannins, which exhibit notable antioxidant properties, effectively scavenge free radicals, and reduce oxidative damage. Additionally, hawthorn polyphenols show significant inhibitory effects on inflammation by modulating relevant signaling pathways and inflammatory mediators, thereby alleviating inflammatory symptoms. This paper summarizes the extraction and separation techniques of hawthorn polyphenols, analyzes their biochemical mechanisms of antioxidant and anti-inflammatory effects, and validates their bioactivity through in vitro and in vivo experiments. The findings provide scientific evidence for the application of hawthorn polyphenols in health fields and offer directions for their future functional development and clinical applications.
