Title: Antioxidant Activity of Echinacea Polyphenols –HPLC-Verified Extracts from Trusted B2B Supplier

Introduction

Echinacea polyphenols, particularly cichoric acid, flavonoids, and alkylamides, demonstrate potent antioxidant properties, making them valuable for nutraceutical and functional food applications. As a GMP-certified supplier, Blue Eyes Biotech Co., Ltd provides HPLC-standardized Echinacea polyphenol extracts with verified radical-scavenging efficacy. This study examines the antioxidant mechanisms of Echinacea polyphenols and presents our quality-controlled extraction process for global buyers.   

Key Antioxidant Mechanisms

1. Free Radical Scavenging   

   - Echinacea polyphenols exhibit 94.05% hydroxyl radical scavenging and 76.2% DPPH inhibition, comparable to ascorbic acid.   

   - Cichoric acid (≥4%) contributes significantly to ROS neutralization via electron donation.   

2. Enzyme Modulation

   - Suppresses NF-κB and NLRP3 inflammasome, reducing oxidative stress-induced inflammation.   

   - Enhances SOD and GSH-Px activity, improving cellular antioxidant defense.   

3.Synergistic Effects

   - Polyphenol-flavonoid complexes in Echinacea show **2–3× higher ABTS+ scavenging** than isolated compounds.   

HPLC-Verified Quality Assurance

- Extraction Method: Ethanol-water (70:30) reflux extraction maximizes polyphenol yield (HPLC-confirmed ≥12% total phenolics).   

- Standardization:   

   - Cichoric acid ≥4% (primary bioactive marker).   

   - Flavonoids ≥2% (quercetin, luteolin derivatives).   

- Purity Tests: Heavy metals (<10 ppm), microbial limits (TAMC < 1000 CFU/g).
