Antioxidant, neuroprotective and anti-inflammatory activity of Curcuma longa extracts: from green extraction to nanoemulsion

Turmeric isn't just a kitchen staple—it's a chemical powerhouse. A new study shows how a green, two-step extraction can turn this golden rhizome into a nanoemulsion with real brain-protecting potential.

The study begins with humble preparation: dried turmeric rhizomes, ground to an average particle size of just 0.402 mm, with a moisture content of 14.38%. These were stored carefully—refrigerated, away from light and oxygen—before undergoing a clever two-stage extraction process.

Key Points

• Green two-step extraction: supercritical CO2 + ultrasound
• Turmeric rhizomes: 0.402 mm particle size, 14.38% moisture
• Nanoemulsion formulation with antioxidant, neuroprotective, anti-inflammatory activity
