| titleOfInvention | A kind of method for building up of Xiao ' erqixingcha oral liquid finger-print and standard finger-print thereof |
| abstract | The present invention relates to Chinese medicine preparation field of quality control, disclose a kind of Xiao ' erqixingcha oral liquid HPLC standard finger-print and method for building up thereof.The method for building up of described finger-print, comprises the steps: the preparation of test sample and reference substance solution, the determination of chromatographic condition, and the mensuration of finger-print, is characterized in that, described chromatographic condition is: determined wavelength is 280 ~ 340nm; Column temperature is 20 ~ 40 DEG C, and flow velocity is 0.8 ~ 1.5ml/min, take octadecylsilane chemically bonded silica as filling agent; Taking acetonitrile as mobile phase A, take pH value as the aqueous solution of 2.0 ~ 4.0 is Mobile phase B, and in 50 ~ 80min, carry out linear gradient elution, the initial volume fraction of mobile phase A is 3 ~ 7%, at the end of volume fraction be 20 ~ 40%.The method can differentiate that the true and false of product is good and bad quickly and accurately, has that method is easy, stable, precision is high, high repeatability and other advantages. |
