Description
Neli Memdueva and nine co-authors compare ways of drawing useful compounds out of marshmallow, a plant used in food and medicine. Their 2026 study tests extracts from its leaves, flowers, and roots. One set used a standard alcohol-water mix, and the other used natural deep eutectic solvents, blends prized as greener options.
Profiling found 35 plant compounds, mostly from two families known for health effects. Alcohol extracts of roots held the most phenolic compounds, while flower extracts fought free radicals best. Germ tests split sharply by solvent: one green blend gave strong antibacterial zones up to about 34 millimeters wide, yet its sibling blend did almost nothing. No extract fought fungi well. The lesson is that the choice of solvent shapes what a plant gives up.
