A water-free, ternary solvent mixture consisting of a natural deep eutectic solvent (NADES), ethanol, and triacetin was investigated concerning its ability to dissolve and extract curcumin from Curcuma longa L. To this purpose, 11 NADES based on chol

Solubility, extraction and stabilization of curcumin extracted from Curcuma longa are still a challenge. Either the solubility power of the extracting solvent mixture is not at its optimum or non-sustainable solvents are used or the curcumin instabil

In preceding papers, it could be shown that mixtures of water, ethanol, and triacetin can significantly boost the extraction of curcuminoids out of Curcuma longa, compared to the usually applied water–ethanol mixtures. To further improve it, additi
