Abstract

The invention discloses a method for establishing a fingerprint of Muli Powder and the fingerprint thereof. The method for establishing the fingerprint spectrum comprises the following steps: step 1: preparation of the reference peak solution; step 2: preparation of the test solution of Oyster Powder; step 3: respectively accurately drawing the quantitative reference peak solution and the test solution and injecting into the liquid phase Chromatograph, record the chromatogram; Step 4: Export the oyster powder fingerprint instrument obtained in step 3, and import it into the Chinese medicine chromatographic fingerprint similarity evaluation system, and select the chromatogram that exists in the chromatogram of different batches of oyster powder for the test. The peaks were taken as common peaks, and the average value calculation method was used to generate the control fingerprint of Mulisan, and the relative retention time and relative peak area of ​​each common peak were calculated. The method for establishing the fingerprint spectrum of the invention has the advantages of simplicity, stability, high precision, good reproducibility and the like. The fingerprint of Muli Powder provided by the invention can comprehensively and objectively characterize the quality of Muli Powder, which is beneficial to comprehensively monitor the quality of medicines.

Description

technical field [0001] The invention relates to a method for establishing a fingerprint of Muli powder and a fingerprint of Muli powder established by the method, belonging to the technical field of quality identification of traditional Chinese medicines. Background technique [0002] Traditional Chinese medicine fingerprint is an effective means of comprehensive analysis to identify the authenticity of Chinese herbal medicines or Chinese patent medicines by using modern analytical techniques, and to evaluate the consistency and stability of the quality of raw materials, semi-finished products and finished products. Compared with the existing identification of a single effective component or index component, the traditional Chinese medicine fingerprint technology integrates various effective chemical information, making the results more scientific and reasonable. At present, the fingerprint of traditional Chinese medicine has become an important method for quality control of...
