Embodiment 1
[0028] Example 1 Preparation of Glycerol Fructose Liposomes
[0029] Prescription: Glycerin 25g
[0030] Fructose 12.5g
[0031] Egg yolk lecithin 250g
[0032] Cholesterol 20g
[0033] Sodium deoxycholate 15g
[0034] Vitamin E 30g
[0035] Sodium chloride 2.25g
[0036] Preparation Process
[0037] (1) 250g egg yolk lecithin, 20g cholesterol, 15g sodium deoxycholate and 30g vitamin E are dissolved in 500ml of n-hexane;
[0038] (2) 25g of glycerin, 12.5g of fructose and 2.25g of sodium chloride are dissolved in 200ml of water;
[0039] (3) the two are mixed and stirred to form a W / O type emulsion, heated and stirred to evaporate, and when the mixture reaches a viscous state, add 50ml of pH value 4.5 acetic acid-sodium acetate buffer solution, continue to heat and stir to evaporate to remove residual n-hexane, Sonicate for 30 minutes, transfer to a high-speed homogeneous mixer, stir and homogenize for 30 minutes to obtain glycero...
