Embodiment 1
[0046] Embodiment 1: the method establishment and verification of the curcuma officinalis medicinal material HPLC fingerprint
[0047] 1. Instruments and Materials
[0048] 1.1 Instruments: Diana P680 high performance liquid chromatography, including P680 infusion pump, ASI-100 autosampler, column thermostat and ultraviolet detector, chromeleon chromatography workstation. BK-240A type ultrasonic cleaning machine (Barker Ultrasonic Technology Group Co., Ltd.), BP211 type electronic analytical balance (Germany Sartorius).
[0049] 1.2 Reference substances and reagents: Curcumadione reference substance (Chengdu Pufeide Biotechnology Co., Ltd., batch number 130713), curcumadiol reference substance, and original curcumol reference substance are self-made, and all reference substances have a purity greater than 98%. Acetonitrile (U.S. Fisher Chemical Reagent Company, chromatographically pure), phosphoric acid (Tianjin Concord Technology Co., Ltd., analytically pure), methanol (Tian...
Embodiment 2
[0063] Example 2: Detection and data analysis of 10 batches of curcuma officinalis fingerprints
[0064] 1.1 Determination of fingerprints of Curcuma officinalis medicinal materials: 10 batches of curcuma officinalis medicinal materials were taken and measured according to the conditions in Example 1, and the HPLC spectra of 10 batches of samples were obtained. No. 1 peak (curcumadiol) is used as a reference, and 12 common peaks have been determined, such as figure 1 . Calculate the relative retention time and relative peak area of each common peak, and the RSD of the relative retention time of each common peak is <0.15%, but the RSD of each relative peak area is relatively large, indicating that the content of medicinal materials in different origins is quite different , the results are shown in Table 2-3.
