Sanguisorba officinalis and long-leaf sanguisorba officinalis medicinal material characteristic spectrum construction method and identification method

The invention relates to the technical field of traditional Chinese medicine identification and quality evaluation, in particular to a garden burnet and long-leaf garden burnet medicinal material characteristic spectrum construction method which comprises the following steps: preparing a reference solution and a test solution; and detecting the reference solution and the test solution by adopting an ultrahigh liquid chromatography to obtain corresponding chromatograms, and comparing the corresponding chromatograms of the reference solution and the test solution to obtain the specific chromatograms of the sanguisorba officinalis and longleaf sanguisorba officinalis medicinal materials. According to the method, the UPLC characteristic chromatograms of the sanguisorba officinalis medicinal material and the long-leaf sanguisorba officinalis medicinal material are constructed, the characteristic peak information of the sanguisorba officinalis medicinal material and the long-leaf sanguisorba officinalis medicinal m
