A HPLC method for rapid determination of 9 organic acids in vinegar was developed.The organic acids were separated by the Prevail Organic acid column in the optimal condition.The recoveries of the method were 89%～104%,the RSDs were 0.38%～1.41%.Two kinds of geographical indicated vinegars,Shanxi extra aged vinegar,Zhenjiang vinegar,were analyzed.The results showed;the organic acids from the vinegars were acetic acid,latic acid,pyruvia acid,formic acid,tartaria acid and citric acid.The contents of latic acid,pyruvia acid in Shanxi extra aged vinegar were different from Zhenjiang vinegar.Compared with non-geographical indicated vinegars,the contents of acetic acid,lactic acid,pyruvia acid and total acid were much more than non-geographical indicated one.Four organic acid contents would be the important factor for the geographical indication discrimination.
