摘要
Curcuminoids originated from the plant Curcuma longa L. show high medical values. Herein, ionic liquids (ILs) were synthesized using fatty acids and alcohol amines to extract curcuminoids. Through single-factor experiments and response surface methodology (RSM) optimization, the extraction amount of curcuminoids by [TEA] [FA-C7] 7 ] aqueous solution reached 34.89 mg/g at a liquid-solid ratio of 16.36 mg/g and an extraction temperature of 36 degrees C, surpassing that of methanol. The extraction capacity of [TEA][FA-C7] 7 ] to curcuminoids was 299.33 mg/g. Furthermore, the separation of extracts and recovery of fatty acids were studied. Quantum chemical calculations and molecular dynamics simulations were performed to investigate the extraction mechanism profoundly. This study not only proposed a novel green solvent for the extraction of curcuminoids from the plant Curcuma longa L. but also provided the possibility of applying fatty acid-based ILs to extract natural medicine efficiently.
