| titleOfInvention | Construction method and detection method of UPLC characteristic map of psyllium |
| abstract | The invention relates to a construction method and a detection method of a UPLC characteristic map of plantain herbs. The steps of the method for constructing a characteristic map are as follows: prepare a reference substance solution with psyllium and verbasin as reference substances respectively; prepare a reference substance solution of a reference medicinal material with psyllium reference medicinal material; respectively take psyllium and standard decoction The sample is extracted with an extraction solvent, filtered, and the obtained filtrate is used as the test solution and the standard decoction need test solution; respectively draw the reference solution, the need test solution, and the standard decoction need test solution and inject it into the ultra-high performance liquid phase Chromatography, determination; compare the chromatogram of the plantain material for testing with that of the standard decoction sample, calibrate the characteristic peaks of 7 water-soluble components, and obtain the UPLC characteristic chromatogram of the plantain material. The characteristic map can be used for qualitative and quantitative analysis of the quality of plantain herbs, can ensure the quality of the traditional plantain decoction prepared by using the herbs, and is also suitable for detecting other preparations containing plantain. |
