| titleOfInvention | Construction method of Digupi UPLC characteristic map and detection method of Digupi |
| abstract | The invention discloses a method for constructing a UPLC characteristic map of Digupi, comprising: (1) respectively taking Digupi reference medicinal material, Digupi B reference substance and Digupi A reference substance, adding a solvent to extract or dissolve , obtain the reference substance solution; (2) take Digupi powder, use methanol-acetic acid mixed solution to extract, obtain the test solution; (3) get the reference substance solution and the need test solution of preset amount, inject A liquid chromatograph, which uses octadecylsilane-bonded silica gel as filler, methanol as mobile phase A, and trifluoroacetic acid aqueous solution as mobile phase B for gradient elution to establish UPLC characteristics of Digupi Atlas. Correspondingly, the present invention also provides a detection method for identifying different bases of Digupi medicinal material and its counterfeit Xiangjiapi. The invention has the advantages of good reproducibility, accuracy and reliability, and the identification of different bases of Digupi and its counterfeit Xiangjiapi can be realized through the established UPLC characteristic map. |
