The invention discloses a method for simultaneously detecting acetylmethylcar-binol and ligustrazine in table vinegar, which comprises the following steps of: (1) pretreatment: table vinegar to be detected and an extraction solvent are blended, and are extracted by the ultrasound; (2) the pretreated table vinegar mixed liquor is detected according to the following chromatographic condition: the column temperature is 45 DEG C, the sample size is 2 MuL, the detection wavelength is 285 to 300 nm, the mobile phase is the volume ratio of the methanol: water solution containing acid of 55:45; the isocratic elution is carried out; the flow rate is 0.8ml/min; (3) the appearance time of the acetylmethylcar-binol and ligustrazine is 1.278 to 1.299min and 1.982 to 2.039min; according to a chromatogram map, whether the table vinegar containing acetylmethylcar-binol and ligustrazine or not is respectively determined. The method is characterized by the simple and fast operation, good repeatability,high precision, low cost and the like.
