CO2 Extraction for Resveratrol – High-Purity & Solvent-Free Extraction

Resveratrol is a potent antioxidant and anti-aging compound found in grapes, red wine, Japanese knotweed, and peanuts. It is widely used in nutraceuticals, pharmaceuticals, and skincare formulations due to its cardiovascular benefits, anti-inflammatory properties, and longevity-enhancing effects.

Traditional resveratrol extraction relies on solvent-based methods, which may leave behind chemical residues and degrade bioactive compounds. CO2 SUPERCRITICAL EXTRACTION MACHINES offer a high-purity, solvent-free alternative that preserves the bioactivity and potency of resveratrol.

1. Why Use CO2 Extraction for Resveratrol?

Supercritical CO2 extraction is ideal for resveratrol isolation because it:

  • Preserves bioactivity by operating at low temperatures (~30-50°C) to prevent thermal degradation.
  • Eliminates toxic solvents – Ensures a pure, contaminant-free extract suitable for pharmaceuticals.
  • Enhances extraction efficiency – CO2 selectively dissolves resveratrol, minimizing impurities.
  • Maximizes bioavailability – Maintains resveratrol’s trans-isomer form, the most active biological state.

2. Key Sources of Resveratrol for CO2 Extraction

SourceResveratrol Content (mg/kg)Additional Benefits
Japanese Knotweed (Polygonum cuspidatum)1,000 – 3,000 mg/kgHigh yield, used in pharmaceuticals
Red Grapes30 – 100 mg/kgSupports cardiovascular health
Red Wine0.1 – 15 mg/LAntioxidant properties
Peanuts0.02 – 1.92 mg/kgRich in polyphenols

Conclusion

CO2 extraction is the gold standard for preserving resveratrol’s bioactivity and purity. Unlike traditional solvent-based methods, it eliminates contaminants, enhances yield, and maximizes potency. SHANG HAI NORTH BROOKS CO2 SUPERCRITICAL EXTRACTION MACHINES provide high-efficiency, solvent-free resveratrol extraction, making them ideal for nutraceutical and pharmaceutical applications.
