| titleOfInvention | Construction method of a HPLC characteristic fingerprint of Celosia japonica and determination of flavonoids content |
| abstract | The invention relates to a method for constructing a HPLC characteristic fingerprint of celosia and determination of the content of flavonoids. The method for establishing the HPLC characteristic fingerprint of the cockscomb medicinal material comprises the following steps: (1) accurately weighing the cockscomb medicinal material to prepare a cockscomb test solution; (2) using high performance liquid phase for the cockscomb test solution Chromatographic analysis was performed to obtain the HPLC characteristic fingerprint of Cockscomb; the method for determination of flavonoids content was: (1) Inject mixed reference solutions of different concentrations into the high-performance liquid chromatograph, take the injection concentration as the abscissa and the peak area as the Draw the standard curve on the ordinate to determine the linear regression equation; (2) inject the cockscomb sample solution to be tested into the high performance liquid chromatograph, and measure the corresponding peak area; (3) calculate by the linear regression equation; The stability and reproducibility are good, which can better evaluate the quality of cockscomb. |
