Objective: To analyze correlation between the content of ligustrazine and storage period of different kinds of vinegar for processing. Method: HPLC was adopted to determine the content of ligustrazine with mobile phase of methanol-0.2 mmol·L-1 ammonium dihydrogen phosphate(46:54) and detection wavelength at 270 nm.Fifteen batches of vinegar with different kinds and storage periods were collected
correlation between the content of ligustrazine and storage period was analyzed by Spearman statistical method. Result: Among these fifteen batches of vinegar
the content of ligustrazine was undetectable in three batches of white vinegar or white rice vinegar
the content of ligustrazine in other batches of vinegar were in the range of 10.1-109.5 mg·L-1
correlation coefficient between the content of ligustrazine and storage period was 0.926. Conclusion: The content of ligustrazine had a large difference in different kinds of vinegar
and it showed a significantly positive correlation with storage period.
