摘要

A method for the determination of anethole in aniseed drinks by high performance liquid chromatography (HPLC) is proposed. A C-18 column and a methanol-water (80:20, v/v) mobile phase with isocratic elution were used. UV detection at 257 nm was carried out. Validation was performed according to the EURACHEM guidelines, considering precision, trueness, robustness, linearity and sensitivity. The detection and quantification limits were 2.3 and 7.7 μg L−1, respectively. Recoveries of 95–101% were obtained. Repeatability, calculated as relative standard deviation was 0.9%. Reproducibility under intermediate precision conditions, expressed as relative standard deviation, was 1.6%. The method was compared with the gas chromatographic one, proposed by the European regulations.
