Description

A kind of hyaluronic acid dressing centrifugal purification device and using method

technical field

The invention relates to a hyaluronic acid dressing centrifugal purification device and a use method thereof, and relates to the field of hyaluronic acid dressing centrifugal purification.

Background technique

Hyaluronic acid, also known as hyaluronic acid, is a disaccharide unit glycosaminoglycan composed of D-glucuronic acid and N-acetylglucosamine. Hyaluronic acid is an acidic mucopolysaccharide. In 1934, Meyer, a professor of ophthalmology at Columbia University in the United States, first isolated the substance from the bovine vitreous. Hyaluronic acid is a biochemical drug with high clinical value, and is widely used in various ophthalmic operations, such as lens implantation, corneal transplantation and anti-glaucoma surgery. It is also used to treat arthritis and accelerate wound healing. Used in cosmetics, it can play a unique role in protecting the skin. It can keep the skin moist, smooth, delicate, soft and elastic. It has the functions of anti-wrinkle, anti-wrinkle, beauty care and restoration of skin physiological functions.

There are three methods of refining hyaluronic acid:

1. Animal tissue: the main raw materials are cockscomb and vitreous body of bull's eye. Degrease and dehydrate the raw material with acetone or ethanol, soak in distilled water, filter, then treat with sodium chloride aqueous solution and chloroform solution, then add trypsin to keep warm to obtain a mixed solution, and finally treat and purify with an ion exchanger to obtain refined transparent uric acid. The extraction rate of this method is extremely low, only about 1%, and the separation process is complicated, which makes hyaluronic acid expensive, reaching 5,000 US dollars/kg, which limits its large-scale use in cosmetics.

2. Microbial fermentation: use glucose as the carbon source fermentation liquid, ferment in the culture medium for 48 hours, after the end of fermentation, filter to remove mycelia and impurities, and then use simple operations such as alcohol precipitation to obtain high-purity products. The hyaluronic acid produced by fermentation method has the advantage that the molecular weight can be set according to the product design. The key to the fermentation method is the selection of strains, such as streptococcus and lactococcus.

3. Chemical synthesis: use natural enzyme polymerization; first use polysaccharide polymers to synthesize "hyaluronic acid oxazepine derivatives", then add water-splitting enzymes to create complexes of derivatives and enzymes, and finally Hyaluronic acid is synthesized by removing the enzymes in the reaction solution at 90°C. The artificial synthesis method can greatly reduce the manufacturing cost of hyaluronic acid, but the structure is less pure.

In the prior art, no matter which of the above extraction methods is used, the purity of hyaluronic acid is relatively low, so centrifugal purification is required.
