Embodiment 1
[0150] Embodiment 1: compound matrine injection
[0151] Sophora flavescens 1400g Baituling 600g.
[0152] Grind the Erwei crude drug into coarse powder, mix it evenly, put it in a percolation tank, add 1% acetic acid equivalent to 5 times of the drug amount, and impregnate for 48 hours, then carry out percolation, collect the filtrate, and concentrate it under reduced pressure at 75°C to Appropriate amount, store in another container, add 5 times the amount of water for injection to the dregs, decoct twice, 1 hour each time, combine the filtrate, concentrate to an appropriate amount, let cool, centrifuge, combine the supernatant with the acid concentrate, adjust to 1000ml, Add ethanol to precipitate twice, first make the alcohol content of the solution reach 65%, let it stand overnight, centrifuge, and recover the ethanol from the supernatant under reduced pressure, concentrate to 500ml, add ethanol to make the alcohol content reach 90%, treat as above, add activated carbon f...
Embodiment 2
[0153] Embodiment 2: the fingerprint detection method of compound Kushen injection described in embodiment 1
[0154] According to high performance liquid chromatography ("Chinese Pharmacopoeia" 2005 edition an appendix VI D), in conjunction with fingerprint spectrum requirement determination:
[0155] Chromatographic conditions and system suitability test: octadecylsilane bonded silica gel is used as filler; linear gradient elution, 0min→A:B=100:0; 60min→A:B=60:40, mobile phase A is 0.01mol / L ammonium acetate aqueous solution, adjust pH value to 8.0 with concentrated ammonia water; mobile phase B is acetonitrile-0.1mol / L ammonium acetate aqueous solution=9:1; detection wavelength is 225nm; column temperature is room temperature; flow rate is 0.8 ml / min;
[0156] Preparation of reference substance solution: Accurately weigh oxymatrine reference substance, add methanol to make a solution containing 0.1mg per 1ml, and obtain it;
[0157] Preparation of the test solution: Accur...
