Embodiment 1
[0025] Preparation of Vitexin Injection
[0026] a. Weigh vitexin 3g, mannitol 180g raw materials and mix evenly, add 600ml water for injection, stir evenly, add 0.1mol / L sodium hydroxide solution 1500ml, stir to dissolve, then adjust to 1mol / L hydrochloric acid solution When the pH is 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 membrane terminal After filtration, it is divided into 10ml vials, each bottle is filled with 3ml, and then freeze-dried at low temperature.
[0027] 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.
[0028] c. Sublimation drying: Lower the temperature of the condenser to below -45°C, start the vacuum pump, and when the vacuum reaches a...
