Embodiment 1
[0035] Example 1: Establishment of a method for fingerprint determination of Danhong injection
[0036] 1.1 Instrument
[0037] Ultra-high liquid chromatograph, (Waters ACQUITY UPLC system, American Waters company), pure / ultra-pure water instrument (Milli-Q, American Millipore company), vortex oscillator (Votex-5, manufactured by Qilin Bell Instrument, Haimen City) Co., Ltd.), low-temperature high-speed centrifuge (J25, American Thermo Forma company), one hundred thousandth balance (METTLER TOLEDO AX205, Swiss METTLER company), ultrasonic cleaning machine (SCIENTZ SB 25-12DTN, Ningbo Xinzhi Biological Technology Co., Ltd. the company).
[0038] 1.2 Test drug
[0039] Standard products: Adenosine (batch number: 110879-200202), uridine (batch number: 110887-200202), phenylalanine (batch number: 140676-200405), 5-hydroxymethylfurfural (5-HMF, batch number: 111626- 200906), protocatechuic acid (batch number: 110809-200604), protocatechuic aldehyde (batch number: 110810-200506), caffeic ...
Embodiment 2
[0085] Example 2: Establishment of fingerprints of 30 batches of Danhong injection
[0086] 2.1 Preparation of test solution
[0087] Precisely measure 2 mL of 30 different batches of Danhong injection, put them in a 10 mL brown measuring flask, add 10% methanol to the mark, and shake well.
[0088] 2.2 Chromatographic conditions:
[0089] Column: ACQUITY HSS T3 (2.1×100mm, 1.8μm); the mobile phase uses 0.1% formic acid water as mobile phase A and acetonitrile as mobile phase B. The volume ratio is that mobile phase A accounts for 97% to 3%, and mobile phase B accounts for 3 ~97%, gradient elution; the specific elution volume concentration ratio is:
[0090] At 0 min, the volume ratio of mobile phase A is 97%, and the volume ratio of mobile phase B is 3%;
[0091] At 7 min to 13 min, the volume ratio of mobile phase A is 81%, and the volume ratio of mobile phase B is 19%;
[0092] At 18 minutes, the volume ratio of mobile phase A is 75%, and the volume ratio of mobile phase B is 25%;
