Embodiment 1
[0043] 1 Instruments and reagents
[0044] 1.1 Instrument
[0045] Waters 2695 high performance liquid chromatography, Waters 2998 detector, Waters Empower chemical workstation; Traditional Chinese medicine chromatographic fingerprint similarity evaluation system (version 2004A); BUG25-12 ultrasonic cleaning machine (220W, 50KHZ, Shanghai Branson Ultrasonic Co., Ltd.); AEG-45SM electronic balance (1 / 100,000, Mettler, Switzerland), BP121S (1 / 10,000, Beijing Sartorius Scientific Instrument Co., Ltd.).
[0046] 1.2 Reagent
[0047] All reagents are analytically pure except that the mobile phase is chromatographically pure; glycyrrhizic acid reference substance (Beijing Hengyuan Qitian Chemical Technology Research Institute, batch number MUST-13083101); liquiritin reference substance (Beijing Hengyuan Qitian Chemical Technology Research Institute) Institute, batch number MUST-130020901); chlorogenic acid reference substance (Beijing Hengyuan Qitian Chemical Technology Research I...
Embodiment 2
[0090] A method for establishing the HPLC fingerprint of a cold medicine, the steps of which are the same as in Example 1.
[0091]The raw materials of cold medicine are: ephedra 6g, mint 5g, cicada slough 5g, honeysuckle 15g, scutellaria baicalensis 12g, bitter almond 9g, Fritillaria 6g, bellflower 6g, licorice 5g; preparation method: mint steam distillation extracts volatile oil, distilled The aqueous solution is stored in another container; the dregs and the remaining ephedra and other eight flavors are decocted with water for 1-3 times, each time for 0.5-1.5 hours, adding 6-10 times the weight of water for the first time, adding 5-8 times the weight of water for the second or third time, Combine the decoction, filter, combine the filtrate with the above aqueous solution, and concentrate to a clear paste with a relative density of 1.18 to 1.20 at a relative density of 90 to 95°C; take the clear paste, add 1-3 parts by weight of sucrose, and 1-3 parts by weight of dextrin, T...
Embodiment 3
[0093] A method for establishing the HPLC fingerprint of a cold medicine, the steps of which are the same as in Example 1.
[0094] The raw materials of cold medicine are: ephedra 3g, mint 9g, cicada slough 3g, honeysuckle 17g, scutellaria baicalensis 9g, bitter almond 16g, Fritillaria 3g, bellflower 8g, licorice 4g; The aqueous solution is stored in another container; the dregs and the remaining ephedra and other eight flavors are decocted with water for 1-3 times, each time for 0.5-1.5 hours, adding 6-10 times the weight of water for the first time, adding 5-8 times the weight of water for the second or third time, Combine the decoction, filter, combine the filtrate with the above aqueous solution, concentrate to a clear paste with a relative density of 1.18-1.20 at a relative density of 90-95°C; the obtained volatile oil is encapsulated with an appropriate amount of β-cyclodextrin, and an appropriate amount of clear paste is added for coloring, and sprayed Drying; take the ...
