摘要： An uncomplicated, valid, and convenient way for detection of lycopene and beta-carotene in fruit juice samples using acid-base-induced deep eutectic solvent (DES) liquid-liquid microextraction (DES-ABLLME) prior to HPLC was developed. The ternary fatty acid DESs were prepared by C-9:C-10:C-11 (2:1:1), which serve as hydrogen bond donors and hydrogen bond acceptors synchronously. In extraction procedure, NH3.H2O was used as the emulsifier and reacted with DESs with a milk solution, which can significantly increase the extraction efficiency. HCl was used as the de-emulsifier, which could break the state of emulsification. At optimum conditions, the calibration graphs were linear in the concentration range from 0.1 to 100 mu g mL(-1) for lycopene and from 0.025 to 5.00 mu g mL(-1) for beta-carotene. The limits of detection (LODs) were 0.05 and 0.002 mu g mL(-1) for lycopene and beta-carotene, respectively. The RSD values were varied from 1.3 to 4.1%. Finally, the proposed method was applied to analyze beta-carotene and lycopene in fruit juices.
