Problems solved by technology

[0003] At present, in the prior art, the commercially available choline alfoscerate is mainly extracted from the by-product of soybean with ethanol for a single time. Placement will absorb moisture in the air, and has a high water absorption rate. After absorbing water, the purity of choline alfoscerate will be seriously reduced, thus greatly weakening the health care performance and medicinal value of choline alfoscerate

preparation example Construction

[0014] The invention provides a kind of preparation method of choline alfoscerate crystal, and this preparation method comprises:

[0015] (1) mixing choline alfoscerate and alcohol to prepare mixture M1;

[0016] (2) carrying out the first concentration of the mixture M1 to obtain the mixture M2;

[0017] (3) mixing the mixture M2 with an organic solvent and performing a second concentration to obtain a mixture M3;

[0018] (4) crystallize after mixing ethyl acetate and the mixture M3, and then filter to obtain crystal M4;

[0019] (5) Drying the crystal M4 under reduced pressure to obtain choline alfoscerate crystals.

[0020] In the above preparation method, the amount of alcohol used is not particularly limited. In order to fully dissolve the choline alfoscerate, preferably, the amount of alcohol used is 420-520 parts by weight relative to 100 parts by weight of choline alfoscerate.

[0021] Of course, the specific type of alcohol can be selected in a wide range, and ca...

Embodiment 1

[0033] (1) Mix and stir choline alfoscerate and ethanol (100:470 by weight) at 38°C for 1.5 hours to prepare mixture M1;

[0034] (2) Under the conditions of 50° C. and 65 KPa, the mixture M2 was first concentrated for 45 minutes to obtain the mixture M2;

[0035] (3) Mix the mixture M2 and ethanol (100:60 by weight) and conduct the second concentration at 35° C. for 2 h to prepare the mixture M3;

[0036] (4) At 48°C, mix ethyl acetate and the mixture M3 (50:100 by weight) under the condition of 70KPa, then crystallize and perform the second filtration to obtain the crystal M4;

[0037] (5) Drying the crystal M4 at 0.7 MPa for 2 hours at 40°C to obtain the choline alfoscerate crystal A1.

Embodiment 2

[0039] (1) Mix and stir choline alfoscerate and propanol (100:420 by weight) at 37°C for 1 hour to prepare mixture M1;

[0040] (2) Under the conditions of 45°C and 50KPa, the mixture M2 was first concentrated for 60 minutes to obtain the mixture M2;

[0041] (3) Mix the mixture M2 and acetone (100:50 by weight) and conduct the second concentration at 30° C. for 1 h to prepare the mixture M3;

[0042] (4) At 45°C, mix ethyl acetate and the mixture M3 (40:100 by weight) under the condition of 60KPa, crystallize and perform second filtration to obtain crystal M4;

[0043] (5) Drying the crystal M4 at 0.6 MPa for 1 h at 35° C. to obtain the choline alfoscerate crystal A2.

Abstract

The invention discloses a preparation method of choline alfoscerate crystal. The preparation method comprises: (1) mixing choline alfoscerate and alcohol to prepare a mixture M1; (2) first concentrating the mixture M1 to prepare The mixture M2; (3) mixing the mixture M2 with an organic solvent and then concentrating the second mixture to obtain a mixture M3; (4) mixing ethyl acetate and the mixture M3 for crystallization, and then filtering to obtain a crystal M4; (5 ) drying the crystal M4 under reduced pressure to obtain choline alfoscerate crystals. The choline alfoscerate crystal prepared by the method has very low water absorption rate in the air, high purity, health care performance and medicinal value.

Description

technical field [0001] The invention relates to the field of preparation of choline alfoscerate, in particular to a preparation method of choline alfoscerate crystal. Background technique [0002] Choline alfoscerate exists widely in organisms, mainly in emulsion and body fluid, and is an important component of the human body. Choline alfoscerate can improve the cognitive ability of the brain, and has excellent prevention and treatment effects on Alzheimer's disease. treatment effect. In addition, it also has the effects of anti-hyperlipidemia and blood vessel protection, and has good preventive and auxiliary therapeutic effects on hypertension and coronary heart disease. Choline alfoscerate can also promote the physical growth of teenagers and improve the memory ability of teenagers. It has extremely high health care performance and medicinal value, so it is widely used in medicine, health care products and functional foods. [0003] At present, in the prior art, the comm...
