The invention discloses a high performance liquid chromatographic analysis method of benzoic acid and sorbic acid in toothpaste and belongs to the technical field of analysis. High performance liquidchromatography is adopted to respectively detect a blank sample, a sample solution and a standard curve solution, and the blank sample, a standard curve, a sample, a sample and a standard curve are sequentially detected (notes: the number of feeding the sample between the two standard curves should not exceed 15, and a quality control sample or a standard curve needs to be added therebetween if the number exceeds 15). The method can quantitatively analyze content of benzoic acid and sorbic acid in a toothpaste sample quickly and accurately and can be used by market regulatory authorities for monitoring quality of commercially available toothpaste products. The method has the advantages of accurate detection result and reliability.
