| titleOfInvention | Construction method and application of UPLC fingerprint of Dingkundan |
| abstract | The invention discloses a construction method and application of UPLC (ultra performance liquid chromatography) fingerprint spectrum of Dingkundan, belonging to the technical field of traditional Chinese medicines. Respectively carrying out ultra-high performance liquid chromatography analysis on the test solution and the reference solution under the chromatographic conditions that 0.1% formic acid water is taken as a mobile phase A and 0.1% formic acid methanol is taken as a mobile phase B, carrying out gradient elution, carrying out the column temperature of 30 ℃, carrying out the sample injection amount of 5 mu L, carrying out the flow rate of 0.2mL/min, carrying out the detection wavelength of 280nm, and analyzing fingerprint information of the captan to obtain 22 common peaks. And (3) adopting traditional Chinese medicine chromatogram fingerprint similarity evaluation system software prepared by the State pharmacopoeia Commission to perform data matching on the liquid chromatogram of the test solution and the reference solution, thus obtaining the standard fingerprint. The fingerprint of the minipill established by the invention can comprehensively reflect the material information of the minipill and accurately and effectively evaluate and control the quality of the minipill. |
