Deep eutectic solvent-based ultrasound-assisted extraction of ginsenosides from ginseng leaves: Quantification and antioxidant activity investigation

What if the humble ginseng leaf, often discarded, holds a treasure trove of bioactive compounds waiting to be unlocked with a whisper of sound and a green solvent?

Ginseng leaves have long played second fiddle to their prized roots. But new research shines a spotlight on these underdog leaves, revealing a potent cocktail of ginsenosides—the compounds behind ginseng's legendary health benefits. The challenge? Getting them out efficiently without harsh chemicals.

Enter Natural Deep Eutectic Solvents (NADES). These eco-friendly mixtures are emerging as a sustainable alternative to traditional organic solvents. In this study, scientists paired NADES with ultrasound, using high-frequency sound waves to gently but effectively shake the precious compounds loose from the leaf matrix.

The team didn't just extract; they quantified. They measured exactly how much ginsenoside was recovered and, crucially, tested the extract's antioxidant activity. The results point to a greener, smarter path for nutraceutical production, proving that sometimes the most valuable ingredients are hiding in plain sight—or rather, in the leaves we often overlook.

Key Points

• NADES paired with ultrasound extracts ginsenosides from leaves.
• Study quantifies ginsenoside yield and antioxidant activity.
• Offers a green alternative to conventional solvent extraction.
