Description
Heba El-Nashar and co-authors profile the chemistry of leaves from Schinopsis balansae, a tannin-rich tree from Argentina's Gran Chaco, and test the extract against skin aging. Their 2026 study uses advanced liquid chromatography with mass detection to name the compounds present. They also measure total phenolic and flavonoid content, two classes tied to antioxidant effects.
The analysis found twenty-two compounds across several chemical families. Lab assays tested whether the extract blocks two enzymes that break down skin's elasticity and collagen. Computer docking then modeled how the compounds might fit those enzymes. The combined evidence supports the extract as a candidate for anti-aging skin products. The tree is also grown in Egypt, outside its native range.
