| titleOfInvention | Construction method and application of UPLC characteristic map of a kind of Qinpi medicinal material |
| abstract | The invention belongs to the technical field of drug analysis, and relates to a method for constructing a UPLC characteristic map of a medicinal material of Qinpi and its application. Wherein, the construction method comprises the following steps: 1) prepare the need testing solution and the reference solution; 2) carry out UPLC analysis to obtain a corresponding chromatogram; 3) use the chromatogram of the reference solution as a control, from the need testing solution Common peaks were selected in the chromatogram to construct the UPLC characteristic map of Qinpi medicinal materials. The constructed characteristic map can be used for the detection of Qinpi medicinal materials and preparations containing Qinpi medicinal materials, and provides a new analytical method for the internal quality control of Qinpi medicinal materials. In addition, the method is simple and easy to implement, has good reproducibility, is accurate and reliable, and is more time-saving and solvent-saving than HPLC, and has less pollution to the ecological environment. |
