preparation Embodiment 1
[0080] Preparation Example 1 Preparation of α-Asarone Injection Emulsion
[0081] Weigh 0.50~50.0g of α-asarone and 50.0~300.0g of soybean oil for injection, put them in a suitable container, heat to 60~80℃ under the protection of nitrogen gas, stir to dissolve; continue to weigh egg yolk lecithin 6.0 ~18.0g, add it, stir to dissolve (if necessary, add 0.10~0.50g of oleic acid, sodium oleate or a mixture of the two), and obtain the oil phase, set aside. In addition, weigh 0~3.0g of Pluronic (F68), 0~25.0g of glycerin, measure about 800mL of water, heat to 60~80℃ under the protection of nitrogen gas, stir to dissolve, and obtain the water phase. Add the above oil phase to the water phase, shear at high speed for 5-15 minutes, add water to 1000mL, and prepare colostrum. Continue to homogenize the colostrum with a high-pressure homogenizer for 1 to 3 times, so that the average particle size of the milk droplets after homogenization is not greater than 0.5 μm, filter through a me...
preparation Embodiment 2
[0082] Preparation Example 2 Preparation of α-Asarone Injection Emulsion
[0083] Weigh 10.0 g of α-asarone, 50.0 g of soybean oil for injection, and 50.0 g of medium-chain triglyceride (MCT) for injection, put them in a suitable container, heat to 60-80°C under nitrogen protection, and stir to make Dissolving; continue to weigh 12.0 g of egg yolk lecithin and 0.3 g of sodium oleate, add them, stir to dissolve, and obtain an oil phase, which is set aside. Separately weigh 22.0 g of glycerin, measure about 800 mL of water, heat to 60-80 °C under the protection of nitrogen gas, stir to dissolve, and obtain the water phase. Add the above oil phase to the water phase, shear at high speed for 5-15 minutes, add water to 1000mL, and prepare colostrum. Continue to homogenize the colostrum with a high-pressure homogenizer for 1 to 3 times, so that the average particle size of the milk droplets after homogenization is not greater than 0.5 μm, filter the membrane, and fill the filtrate ...
preparation Embodiment 3
[0084] Preparation Example 3 Preparation of α-Asarone Injection Emulsion
[0085] Weigh 20.0 g of α-asarone, 100.0 g of soybean oil for injection, and 100.0 g of medium-chain triglyceride (MCT) for injection, put them in a suitable container, heat to 60-80°C under nitrogen protection, and stir to make Dissolving; continue to weigh 12.0 g of egg yolk lecithin and 0.3 g of oleic acid, add it, stir to dissolve, and obtain an oil phase for later use. Separately weigh 22.0g of glycerin, measure about 800mL of water, heat to 60~80°C under the protection of nitrogen gas, and stir to dissolve; the aqueous phase is obtained. Add the above oil phase to the water phase, shear at high speed for 5-15 minutes, add water to 1000mL, and prepare colostrum. Continue to homogenize the colostrum with a high-pressure homogenizer for 1 to 3 times, so that the average particle size of the milk droplets after homogenization is not greater than 0.5 μm, filter the membrane, and fill the filtrate into ...
