Phenolic / Polyphenol Comparison Matrix including:
-Gallic acid (GA)
-Caffeic acid (CA)
-Ferulic acid (FA)
-Ellagic acid (EA)
-DHCA (3,4-dihydroxycinnamic acid variant class)
-HCAs (general hydroxycinnamic acids class)
-Rosmarinic acid
-Propolis (CAPE-rich context)
-Perilla (rosmarinic-rich context)
-Moringa
-Date fruit extract
True Phenolic Acids (GA, CA, FA, EA, DHCA, HCAs)
-Core identity: redox modulators
-Anti-inflammatory signature: NF-κB ↓
-Nrf2 activation common in normal tissue
-Tumor cytotoxicity usually requires ≥10–50 µM
-Bioavailability often limiting
Polyphenol-Rich Extracts (Propolis, Perilla, Moringa, Date)
-Effects depend on composition
-Strongest NF-κB inhibition: Propolis (CAPE)
-Strongest biphasic redox: Gallic, Caffeic
-Weakest direct tumor evidence: Date fruit extract
