Fructus rosae laevigatae standard decoction lyophilized powder and production process thereof

[0022] A standard decoction freeze-dried powder of Fructus Rosa Fructus, take 2 mL of standard decoction of Fructus Rosa Fructus, add 10% freeze-drying protective agent, freeze-dry to obtain freeze-dried powder. The lyoprotectant is maltodextrin. The density of described Fructus Rosa Rosa standard decoction is 1g / mL. The freezing temperature of the freeze-drying is -50°C, and the freezing time is not less than 3 hours; after the freezing is completed, the temperature is raised to -35°C within 8 minutes, and after being maintained for 20 hours, the temperature is raised to -30°C and maintained for 18 hours; Keep at -20°C for 10 hours, continue to raise the temperature to -10°C, and keep for 5 hours; raise the temperature to 30°C within 8 minutes for analysis and drying.

[0023] Adding a freeze-drying protective agent into a certain amount of standard decoction of Rosa chinensis can effectively prevent the freeze-dried product from excessive viscosity and serious collapse durin

[0026] The difference between Example 2 and Example 1 is that 2 mL of the standard decoction of Fructus Rosa Radix is ​​taken, 1% of lyoprotectant is added, and the lyophilized powder can be obtained after lyophilization. The lyoprotectant is maltodextrin. The freezing temperature of the freeze-drying is -55°C, and the freezing time is not less than 2 hours; after the freezing is completed, the temperature is raised to -40°C within 5 minutes, and after being maintained for 15 hours, the temperature is raised to -33°C and maintained for 15 hours; Keep at -25°C for 5 hours, continue to raise the temperature to -15°C, and keep for 3 hours; within 5 minutes, raise the temperature to 20°C for analysis and drying.

[0027] The sublimation temperature is set to -40°C and -30°C, the production efficiency is high and the product quality is good. Catechin has various functions such as anti-tumor, anti-oxidation, anti-bacteria, and protection of heart and brain organs. The freeze-dried pro

[0029] The difference between Example 3 and Example 1 is that 2 mL of the standard decoction of Fructus Rosa Rosa Fructus is taken, 30% of lyoprotectant is added, and the lyophilized powder can be obtained after lyophilization. The lyoprotectant is maltodextrin. The freezing temperature of the freeze-drying is -45°C, and the freezing time is not less than 4 hours; after the freezing is completed, the temperature is raised to -32°C within 10 minutes, and after being maintained for 25 hours, the temperature is raised to -28°C and maintained for 20 hours; Keep at -15°C for 15 hours, continue to raise the temperature to -5°C, and keep for 10 hours; within 10 minutes, raise the temperature to 35°C for analysis and drying.
