polyphenol-bioactivity
Polyphenol-bioactivity refers to the biological activity and functional properties of polyphenolic compounds—plant secondary metabolites with multiple phenolic groups. In plant science, understanding polyphenol bioactivity is critical because these compounds serve fundamental roles in plant defense mechanisms, stress tolerance, and environmental adaptation. This knowledge is essential for assessing plant quality, enhancing crop resilience, and developing plant-based solutions in agriculture and biotechnology.

A polyphenol-rich extract from coffee leaves reduced weight gain and inflammation in mice on high-fat diets by strengthening gut barrier function and improving liver health, suggesting coffee leaf compounds may prevent diet-related metabolic disease through changes to gut bacteria and bile acid metabolism.
WEAC supplementation at 100-200 mg/kg reduced body weight, serum TNF-α, and inflammatory markers across multiple tissues (colon, liver, brain)
Improved intestinal barrier integrity through upregulation of tight-junction proteins and 50%+ reduction in intestinal permeability markers
Decreased hepatic lipid accumulation and improved lipid profiles (reduced triglycerides, total cholesterol, and LDL cholesterol levels)
