[0013] The liquid phase data is obtained by determination, and the content of the reference index component in the traditional Chinese medicine composition is calculated.
[0014] Based on the above determination method, the content of each reference index component in the freeze-dried powder of the traditional Chinese medicine composition is further limited and required: each 1 g of the substance reference contains not less than 0.033 mg of quercetin-3-O-β-D-glucose-7-O-β-D-gentiopicroside; each 1 g of the substance reference contains not less than 2.329 mg of paeoniflorin; each 1 g of the substance reference contains not less than 0.100 mg of glycyrrhizin; each 1 g of the substance reference contains not less than 5.130 mg of baicalin; each 1 g of the substance reference contains not less than 0.009 mg of aloe-emodin; each 1 g of the substance reference contains not less than 0.200 mg of 6-shogaol; each 1 g of the substance reference contains not less than 0.029 mg of rhein; each 1 g of the substance reference contains not less than 0.013 mg of chrysophanol; and each 1 g of the substance reference contains not less than 0.006 mg of emodin methyl ether.

[0101] Four, the establishment of fingerprint and similarity evaluation
[0102] The sample solution of 15 batches of material reference was prepared by the method in experimental example 2, and was determined by injection under the chromatographic conditions in experimental example 2. The chromatograms of each batch were recorded, and the software of "Traditional Chinese Medicine Chromatographic Fingerprint Similarity Evaluation System (2004.A version)" was used for analysis (reference spectrum: S6; time window width: 0.1 min; median method; similarity calculation: multi-point correction and full spectrum peak matching). The fingerprint of the sample solution of 15 batches of material reference was calculated by the software to generate the control fingerprint. The results showed that the similarity of the sample solution (S1-S15) of 15 batches of material reference with the control fingerprint (R) was 0.789, 0.808, 0.854, 0.877, 0.815, 0.822, 0.937, 0.944, 0.967, 0.883, 0.903, 0.889, 0.939, 0.925, 0.933, respectively, all greater than 0.7, indicating that the overall similarity of 15 batches of material reference was good, and the fingerprint overlay of the 15 batches of material reference was shown in Figure 1 .

The sample solution of the material reference of S1 was prepared by the method of experimental example 2, and was compared with the fingerprint of each single herb decoction piece solution, each negative sample solution and the mixed control solution prepared in experimental example 3. It was found that the sample solution of the material reference of S1 had 17 common peaks at 254 nm wavelength, as shown in Figures 2-3 , in which peak 3 (quercetin-3-O-β-D-glucose-7-O-β-D-gentiopicroside) and 5 belonged to the decoction piece of Semen Platycladi, peak 1 and 4 (paeoniflorin) belonged to the decoction piece of Radix Paeoniae Alba, peak 2, 6 (glycyrrhizin) and 15 belonged to the decoction piece of Glycyrrhiza, peak 8 (baicalin), 9, 10 and 11 belonged to the decoction piece of Radix Scutellariae, peak 13 (6-gingerol) belonged to the decoction piece of Rhizoma Zingiberis Recens, and peak 7, 12 (aloe emodin), 14 (rhein), 16 (chrysophanol) and 17 (emodin methyl ether) belonged to the decoction piece of Radix et Rhizoma Rhei. It can be seen that the main components of the material reference prepared by the process in experimental example 1 were completely transferred from the decoction piece to the material reference, and the attribution relationship was relatively clear.
