Embodiment 1
[0064] Example 1 The construction method of the HPLC fingerprint of hawthorn broken wall decoction pieces
[0065] A method for constructing the HPLC fingerprint of hawthorn broken-wall decoction pieces, comprising the following steps:
[0066] S1. Preparation of the test solution: Precisely weigh the broken pieces of hawthorn, add 70% methanol according to the mass volume ratio of 1:25, infiltrate and homogenate at 12,000 rpm for 2 minutes, take it out and cool to room temperature, and make up with 70% methanol Lose weight, shake well, filter through a 0.22 μm microporous membrane after coarse filtration, and take the filtrate to obtain the test solution;
[0067] S2. Preparation of reference substance solution: take chlorogenic acid as reference substance, add methanol to prepare reference substance solution;
[0068] Chromatographic conditions for S3.HPLC analysis: pass the test solution obtained in S1 through an octadecylsilane bonded silica gel column, the column tempera...

[0072] Example 2 Establishment of shared pattern of fingerprints of hawthorn broken-wall decoction pieces
[0073] 1. Identification of reference peaks
[0074] According to the construction method of Example 1, measure the HPLC fingerprint of reference substance solution chlorogenic acid, record the chromatogram, and compare it with the HPLC fingerprint of hawthorn broken wall decoction pieces, analyze the retention time and the ultraviolet absorption situation of the corresponding peak, Such as figure 1 shown.
[0075] Point out: No. 4 peak is chlorogenic acid. Among them, peak No. 6 has moderate height, good resolution and moderate retention time, and was selected as the reference peak.
[0076] 2. Establishment of fingerprints and confirmation of common peaks
[0077] Take 10 batches of hawthorn broken wall decoction pieces (batch numbers are UGP20181201, UGP20181202, UGP20181203, UGP20181204, UGP20181205, UGP20181206, UGP20181207, UGP20181208, UGP20181209, UGP20181210...

[0083] Embodiment 3 methodological verification
[0084] 1. Specific inspection
[0085] Get the hawthorn broken wall decoction piece that batch number is UGP20180505, prepare need testing solution and blank need testing solution according to the method for embodiment 1 step S1, sample injection, measure according to the chromatographic condition of embodiment 1 step S3, record chromatogram, as Figure 4 shown. The results show that the solvent has basically no absorption under the chromatographic conditions, and has little influence on the chromatogram of the sample. It shows that the specificity of the established method is good.
[0086] 2. Instrument precision
[0087]Get the hawthorn broken wall decoction piece that batch number is UGP20180505, prepare need testing solution according to the method for embodiment 1 step S1, continuous sample injection 6 times, measure according to the chromatographic condition of embodiment 1 step S3, record chromatogram (see Figure 5...
