Embodiment 1
[0029] (1) Shark chondroitin sulfate 5g, dissolved in pH8.0 buffer solution at a concentration of 5% (W / V), added 50IU chondroitin sulfate AC enzyme, stirred at 37°C for 48 hours; after the reaction, added 5 times Precipitate with 95% ethanol by volume and freeze-dry to obtain the chondroitin sulfate oligosaccharide mixture.
[0030] (2) Dissolve the sample obtained in step (1) to 0.1g / mL with 0.15mol / L NaCl solution, the chromatographic column size is 2.6×20cm, Q Sepharose Fast Flow strong anion exchange packing, the ultraviolet detection wavelength is 232nm, the injection volume 10ml, mobile phase 0.15mol / L and 1.2mol / L NaCl solution, flow rate 1.33mL / min, gradient elution, collect the elution volume at 1350-1550ml, which is the last peak. See figure 1 .
[0031] (3) The fractions collected in step (2) were desalted by G-25 dextran gel filtration, and then concentrated and freeze-dried.
[0032] (4) Dissolve the lyophilized sample in step (3) into 0.1g / mL with purified wa...
