The invention relates to a chondroitin sulfate extraction method, and especially relates to a method for extracting chondroitin sulfate from sturgeon bones through a diluted alkali-enzymatic hydrolysis technology. The method is characterized in that alkali liquid extraction and salt precipitation are carried out to remove proteins, and the method concretely comprises the following steps: adding a NaOH solution with the concentration of 3% to dried sturgeon cartilages according to a solid-to-liquid ratio of 1:6 (g/ml), extracting at 35 DEG C for 2 h, taking the obtained supernatant, adding 3% (g/ml) of NaCl, allowing the obtained solution to stand at 90 DEG C for 20 min, and filtering the solution; and carrying out enzymatic hydrolysis by using pancreatin. The extraction method greatly improves the content of an effective component hexosamine in the above product. The chondroitin sulfate (CS) is connected with serine residues of protein molecules through oligomeric glucosides, so the CS released in the diluted alkali-enzymatic hydrolysistechnology may be still connected with a plurality of amino acid residues or polypeptides due to the certain specificity of enzyme hydrolysis peptide chains. The extraction method reduces the use amount of protease through setting the heating salt precipitation step in order to reduce the production cost, so the problem of slight high nitrogen content of the above product is solved to a certain degree.

The present invention provides a new class of compounds presenting a high compatibility with tissues and organic fluids. Such new compounds are polysaccharides essentially formed of units of uronic acid and/or hexosamine, containing nitro groups -ONO2 covalently bonded to the saccharide structure. Preferably, the polysaccharides according to the invention are prevalently formed of disaccharide repeating units formed of uronic acid and hexosamine. These compounds, in psychological conditions, selectively release NO, allowing a reduction in the amount of NO needed to achieve a determined therapeutical effect. This result has been achieved by functionalizing polyssacchrides essentially formed of units of uronic acid and/or hexosamine, with subsituents containing a ONO<custom-character file="US20030181417A1-20030925-P00900.TIF" wi="20" he="20" id="custom-character-00001"/>2? group.
