Embodiment 1

[0026] Under the protection of nitrogen, weigh 30 g of soybean oil, heat to 40°C, add 1 g of egg yolk lecithin and 0.001 g of astragaloside IV under high-speed stirring, and stir evenly as the oil phase. Add 1 g of glycerol for injection to 600 ml of water for injection, mix well and filter with a 0.45 μm filter membrane as the water phase. Add the oil phase to the water phase under high-speed stirring to make colostrum. Add water for injection to 1000ml, adjust the pH to 3.0, homogenize with a high-pressure homogenizer to obtain a white milky liquid, filter, fill, seal, and sterilize.

Embodiment 2

[0028] Under the protection of nitrogen, weigh 50 g of soybean oil, heat to 60°C, add 10 g of egg yolk lecithin and 1 g of astragaloside IV under high-speed stirring, and stir evenly as the oil phase. Add 20 g of glycerol for injection to 600 ml of water for injection, mix well and filter with a 0.45 μm filter membrane as the water phase. Add the oil phase to the water phase under high-speed stirring to make colostrum. Add water for injection to 1000ml, adjust the pH to 5.0, homogenize with a high-pressure homogenizer to obtain a white milky liquid, filter, fill, seal, and sterilize.

Embodiment 3

[0030] Under the protection of nitrogen, weigh 100 g of sesame oil, heat it to 50°C, add 12.5 g egg yolk lecithin and 0.5 g astragaloside IV under high-speed stirring, and stir evenly as the oil phase. Add 22.5 g of glycerol for injection to 500 ml of water for injection, mix well and filter with a 0.45 μm filter membrane as the water phase. Add the oil phase to the water phase under high-speed stirring to make colostrum. Add water for injection to 1000ml, adjust the pH to 8.0, homogenize with a high-pressure homogenizer to obtain a white milky liquid, filter, fill, seal, and sterilize.

Abstract

A lipid emulsion of astragaloside A is proportional prepared from astragaloside A, oil, surfactant, isotonic regulator, cosolvent and water for injection. Its preparing process is also disclosed.

Description

Technical field: [0001] The invention relates to an astragaloside IV fat emulsion and a preparation process thereof. Background technique: [0002] Astragaloside IV is one of the monomers of astragalus. In addition to its anti-inflammatory, antihypertensive, and improving myocardial ischemia effects, recent studies have shown that it has the following pharmacological effects: it can inhibit the increase in the amount of malondialdehyde in brain tissue after cerebral ischemia , And improve the activity of glutathione peroxidase; it has obvious anti-liver injury (hepatitis, liver fibrosis, liver tumor), treatment of rheumatoid arthritis and anti-aging effects; it has the effect of renal ischemia-reperfusion injury in rats Protective effect; has a protective effect on rats with early diabetic nephropathy. Astragaloside IV is extremely active, especially in diabetic nephropathy and anti-tumor. [0003] Astragaloside IV is difficult to dissolve in water, and the higher the purity, the...
