Water an eco-friendly crossroad in green extraction: An overview

Water, the most ancient solvent known to humanity, is emerging as the unexpected hero in the quest for greener chemistry. This review reveals how this everyday molecule is reshaping the future of natural product extraction.

Imagine a solvent that has been used for millennia, yet only now are we unlocking its full potential in the lab. This review dives into water's dual role as both a green solvent and a co-extractant, tracing its journey from ancient practices to modern environmental imperatives. The authors argue that water is not just a passive medium but an active 'crossroad' where traditional wisdom meets cutting-edge innovation.

The paper surveys a spectrum of extraction methods for natural products, from conventional techniques to groundbreaking processes, all centered on water. It highlights how this simple molecule can replace hazardous organic solvents, reducing environmental impact while maintaining efficiency. But the story doesn't stop at the bench—the review also confronts the elephant in the room: wastewater. By addressing the challenge of water waste, the authors call for a more responsible use of this finite resource.

Looking ahead, the review offers future insights that position water as a cornerstone of sustainable chemistry. It's a call to action for researchers to rethink their solvent choices, not just for better yields, but for a healthier planet. After all, the greenest solvent might be the one we've had all along.
