Embodiment 1
[0027] Embodiment 1: Preparation of Vitexin Mannitol for Injection
[0028] a. Weigh 30g vitexin and 180g mannitol and mix them evenly, add 600ml water for injection, stir evenly, then add 1500ml 0.1mol / L sodium hydroxide solution, stir to dissolve, then adjust to 1mol / L hydrochloric acid solution When the pH is around 8.5, add water for injection to 3000ml, add 0.05% activated carbon for needles, stir for 10 minutes, decompress and coarsely filter with a microporous titanium filter, decarbonize, check the content and pH, and then pass through a 0.22μm microporous filter After membrane terminal filtration, it was divided into 10ml vials with 3ml in each bottle, and then freeze-dried at low temperature.
[0029] b. Pre-freezing: Put the subpackaged medicines on the inner shelf of the freeze-drying box and start to pre-freeze to +25°C ~ -40°C for 2 hours; -40°C for 3 hours.
[0030] c. Sublimation drying: Lower the temperature of the condenser to below -45°C, start the vacuum p...
Embodiment 2
[0032] Embodiment 2: the inspection of vitexin mannitol for injection
[0033] (1) Take 14.0 mg of this product, add ethanol to make a solution containing 20 μg vitexin per 1 ml, as the test solution; take vitexin reference substance to make the reference solution in the same way. Test according to thin-layer chromatography (Appendix VIB of Chinese Pharmacopoeia 2010 Edition), absorb each 5 μ l of the test solution and the reference solution, respectively spot on the same polyamide membrane, use 36% acetic acid as the developing agent, develop, take out, Dry it in the air, spray it with 1% aluminum chloride solution, blow it dry with hot air, and inspect it under an ultraviolet lamp (365nm). In the chromatogram of the test product, on the position corresponding to the chromatogram of the reference product, fluorescent spots of the same color appear;
[0034] (2) Take 7.0 mg of this product, add ethanol to make a solution containing 10 μg of the main drug per 1 ml, and measure ...
