Embodiment 1
[0038] Embodiment 1: the construction of Dingkundan UPLC fingerprint
[0039] 1.1 Instrument
[0040] Waters Acquity UPLC H-Class ultra-high performance liquid chromatography system, Empower workstation with quaternary gradient pump, autosampler, PDA detector (Waters company); ultrasonic cleaner (KQ2200DB numerical control ultrasonic cleaner, Kunshan Ultrasonic Instrument Co., Ltd. company); one ten thousandth balance (CPA225D electronic analytical balance, Sartorius Scientific Instrument Co., Ltd.); Milli-Q Integral Water Purification System (Millipore, USA).

Embodiment 2
[0053] Example 2: Dingkundan control characteristic map and similarity evaluation
[0054] A total of 19 batches of Dingkundan were taken from different production batches, analyzed respectively according to the established Dingkundan fingerprint analysis method, and the UPLC fingerprint superimposition diagrams of 19 batches of samples were obtained (such as image 3 shown). Based on the chromatograms of the above-mentioned 19 batches of samples, use the "Chinese Medicine Chromatographic Fingerprint Similarity Evaluation System" (2008 Edition) recommended by the Pharmacopoeia Commission to perform data processing to obtain a common pattern characteristic spectrum, which is the Dingkundan control characteristic spectrum R (Such as figure 1 shown). The retention times of the main chromatographic peaks of the 19 batches of samples were basically the same, and the 22 peaks with good separation under the detection conditions were determined to be their common chromatographic pea...
