Preconcentration of Cinnamic Acid Derivatives in Traditional Chinese Medicines by an Effective Dispersive Liquid‐Liquid Microextraction Based on a Hydrophobic Deep Eutectic Solvent

ABSTRACT A dispersive liquid‐liquid microextraction based on hydrophobic deep eutectic solvent (hDES) was developed for the extraction and quantification of four cinnamic acid derivatives in traditional Chinese medicines coupled with high‐performance liquid chromatography‐ultraviolet detection. In t...
