Phenolic Compounds

Definition

Phenolic compounds are a group of chemicals naturally found in plants, known for their antioxidant properties and potential health benefits.

Scientific / Technical Definition

Phenolic compounds are a diverse class of chemical compounds containing one or more hydroxyl groups attached to an aromatic benzene ring. They are widely distributed in the plant kingdom, functioning primarily as defense mechanisms against ultraviolet radiation, pathogens, and herbivores. Researchers often study these compounds due to their potential biological activities, such as antioxidant, anti-inflammatory, and anticancer effects.

Benefits

• Act as antioxidants, protecting cells from damage by free radicals
• Reduce inflammation and lower the risk of chronic diseases
• May improve cardiovascular health
• Potentially help in the prevention of some cancers
• Support cognitive functions and mental health

Examples

• Berries (e.g., blueberries, strawberries)
• Nuts (e.g., walnuts, almonds)
• Tea (especially green tea)
• Red wine
• Dark chocolate
• Spices like cloves and ginger

Additional Information

• Effects: Phenolic compounds have several biological effects, including modulation of enzyme activities, scavenging of free radicals, and altering cellular signaling pathways. Their antioxidant properties are particularly noteworthy in reducing oxidative stress.
