The invention relates to a fingerprint spectrum determination method of a ligusticum wallichii tea-blending granular preparation, which comprises the following steps: (a) preparing ligusticum wallichii tea-blending preparation test sample: precisely weighing a proper quantity of ligusticum wallichii tea-blending preparation, adding a solvent for reflux extraction, centrifuging the extracting solution, evaporating and drying supernate, dissolving with water, extracting with n-butyl alcohol, collecting n-butyl alcohol extracting solution, evaporating and drying, dissolving with 70% methyl alcohol, and filtering by using a microfiltration membrane to obtain the test sample; (b) chromatograph condition: with octadecylsilane bonding silica gel as the chromatograph column of filler, carrying out gradient elution, wherein a flowing phase A is acetonitrile, the flowing phase B is 0.01-0.2% formic acid aqueous solution, and the detection wavelength is 230-280nm; and (c) determination: precisely adsorbing test sample solution, introducing in a liquid chromatograph, recording the chromatogram to finally obtain the characteristic fingerprint spectrum of the ligusticum wallichii tea-blending preparation. The HPLC (High Performance Liquid Chromatography) characteristic fingerprint spectrum analysis method for ligusticum wallichii tea-blending preparations, such as the granular preparation, is simple to operate, has the advantages of high precision and repeatability, and is suitable for controlling the quality of the ligusticum wallichii tea-blending preparations, such as the granular preparation.
