Abstract
The invention discloses a kind of preparation methods of three creatines HMB salt.Creatine and HMB are first dissolved in the alcohol solution being mixed to form by alcohol, water by the preparation method, then are crystallized, washed, dry through separation successively after by elder generation, and three creatine HMB salt are obtained.The present invention is reacted with creatine and HMB in alcohol solution, then successively through separation crystallization, washing, drying, step is simple, improves yield.
Description
Technical field
The present invention relates to the technical field of creatine more particularly to a kind of preparation methods of three creatines HMB salt.
Background technology
HMB is the metabolite of leucine in human body.United States Patent (USP) reports that it can enhance the immunocompetence of mammal
(US 4992470) promotes human muscle to grow (US 5028440), reduces body fat, i.e., total cholesterol and low in blood
Density lipoprotein-cholesterol is to reduce the generation of coronary heart disease and angiocardiopathy.In order to obtain preferable oral administration biaavailability,
HMB currently on the market is water-soluble preferable mineral salt such as HMB-Na, HMB-K, HMB-Ca.These mineral salts water in vivo
It is absorbed after solution, since this absorption pattern limits the amount into the active HMB of blood plasma, to affect drug effect.
Creatine is primarily present in the liver of animal, as a kind of big right nutrient, can be promoted muscle cell growth, be increased
The growth synthesis for adding the water content of muscle cell, helping muscle cell storage energy, increasing protein, therefore can be highly effective
It improves the endurance of muscle strength and human body and improves sports achievement in ground.Creatine is not hormone, and creatine, which is not present, in human body relies medicine
Property or physiological side reaction, therefore creatine is a kind of safe nourishing tonic for sport.
Three creatine HMB salt are a kind of salt containing creatine cations, HMB anion.Existing report is to it in the prior art
Preparation method.
Invention content
In view of this, the present invention provides a kind of preparation method of three creatines HMB salt, the yield of the preparation method is higher, closes
It is simple at step.
The preparation method of the three creatine HMB salt of the present invention, includes the following steps：
（1）Creatine and HMB are dissolved in the alcohol-water solution being mixed to form by alcohol, water, and are allowed to react；
（2）It will be through step（1）Obtained reaction mixture is crystallized after through separation by elder generation, is washed, dry successively, obtains three creatines
HMB salt.
It is aforementioned, step（1）In；Reaction is the amino by creatine（Basic group）With the carboxyl of HMB（Acidic-group）Hair
Raw neutralization reaction.The temperature of the reaction is preferably 10~60 DEG C.At a temperature of this, the reaction time is 0.5~5h.
The volume of alcohol and water is 1 better：2~8.
Preferably, alcohol C1~4Alcohol, such as methanol, ethyl alcohol, isopropanol, isobutanol etc..
It is aforementioned, step（2）In：The separation crystallization is crystallisation by cooling.Herein, crystallisation by cooling refers to by cooling so that molten
The dissolubility of matter reduces and makes solution supersaturation, the method to precipitate crystal.
Preferably, the cooling temperature of crystallisation by cooling is 2~6 DEG C.
Dry mode is vacuum drying, or other modes.
As a preferred mode, vacuum drying temperature is 60~80 DEG C.
Washing uses alcoholic solvent.
The present invention is reacted with creatine and HMB in alcohol-water solution, then successively through separation crystallization, washing, drying, step is simple,
Improve yield.
Specific implementation mode
The technical solution further illustrated the present invention with reference to embodiment.
