| titleOfInvention | A method of removing keratan sulfate from chondroitin sulfate crude extract |
| abstract | The invention belongs to the method for keratan sulfate is removed in biotechnology more particularly to a kind of crude extract from chondroitin sulfate.After sodium hydroxide solution reaction is added in the present invention in chondroitin sulfate crude extract solution, hydrochloric acid is added and adjusts pH value, filters to get filtrate, it is 45 48ms/cm that sodium chloride is added in filtrate and adjusts electrical conductivity of solution, then ethanol solution is added, control ethanol solution flow velocity is 10 15mL/（L·min）, so that chondroitin sulfate is precipitated, filters to obtain sediment, sediment dry chondroitin sulfate finished product after dehydration.Present invention process condition is easy to control, at low cost, easy to operate, requires laboratory apparatus low, thoroughly solves that keratan sulfate is removed from chondroitin sulfate is difficult, it is difficult to the problem of industrialized production. |
