[0066] Example 2 Detection of fingerprints of amino acid components in 10 batches of Xiasangju sugar-containing granules

[0067] Get 10 batches of Xia Sangju granules, detect according to the conditions of Example 1, and obtain the amino acid HPLC collection of samples of 10 batches of samples, as figure 2 As shown, by comparing 10 batches of HPLC chromatograms, the similarity evaluation is carried out to determine its characteristic common peak:

[0068] There are 12 common peaks in the fingerprint spectrum. Now the retention time of the spectrum, the average value of the peak area and the RSD value are summarized, as follows:

[0069] Peak No. 1 is aspartic acid, the average retention time RT is 19.54min, the RSD is 0.05%, the peak area is 785808, the RSD is 25.04%, accounting for 1.58% of the total peak area.

[0070] The No. 2 peak is serine, the average retention time RT is 20.45min, the RSD is 0.05%, the peak area is 721818, the RSD is 33.86%, accounting for 1.46% of ...
