Deep eutectic solvents (DES) and ionic liquids (ILs), specifically natural deep eutectic solvents (NADES), allow for the extraction of natural products using environmentally friendly solvents instead of organic solvents. Here we describe the extraction of anthocyanins from a medicinal plant using NADES prepared either by evaporating method or heating-and-stirring method with the help of ultrasound-assisted extraction (UAE). The NADES extract can be qualified by the high-performance liquid chromatography (HPLC) method, which can separate the component of NADES with target compounds from medicinal plant.

The NADES extract can be qualified by the high-performance liquid chromatography (HPLC) method, which can separate the component of NADES with target compounds from medicinal plant.
