The invention relates to the field of biochemistry, and discloses a detection method of sodion and a kit. The method provided by the invention comprises the following steps of: mixing one component of agaropectin, Arabic gum or polyethylene glycol 2000 with 6-antimony potassium hydroxide to form a mixed liquor, allowing the mixed liquor in a buffer system of pH 7.2-7.5 to react with a sample to be detected and mixtalol to obtain a 6-sodium antimonite hydroxide suspending liquid, detecting absorbance at a 630nm wavelength, performing turbidimetry with a standard solution which undergoes the above same processing, and calculating the sodion concentration of the sample to be detected. The kit provided by the invention comprises one component of 200-300mg / L of agaropectin, 1000-1500mg / L of Arabic gum or 5-10g / L of polyethylene glycol 20000, 12-15g / L of 6-antimony potassium hydroxide and mixtalol. The method provided by the invention enables rapid precipitation of the reaction between Na+ and 6-antimony potassium hydroxide, avoids precipitation polymerization, raises the accuracy of the detection, and can be widely used to detect the sodion concentration.

An odd agaropectin oligose monomer, such as agartriose, agarpentose, agarheptose, or agarnonose, is prepared through adding water to agaropectin or agaropectinose, adding acid, thermal reacting at 50-90 deg.C for 15-480 min, centrifugal separation, evaporation concentrating, adding organic solvent, centrifugal separation, concentrating supernatant, chromatographic column separation, and freeze drying.

The invention relates to a high-pressure water vapor degradation method for marine sulfated polysaccharides. The method is characterized in that the marine sulfated polysaccharides are prepared into water solution, then the water solution is treated by high-pressure water vapor at the temperature of 101-150 DEG C for 0.01-24hours, and the obtained treatment solution is dried for obtaining degraded products of the polysaccharides. The marine sulfated polysaccharides comprise seaweed fucoidan, carrageenan and agaropectin which are sourced from marine plants, as well as sea cucumber chondroitin sulfate, sea cucumber fucoidan and abalone sulfated polysaccharides, which are sourced from marine animals. The method has the advantages that no inorganic salt is introduced, and the final products can be obtained by drying after degradation without desalinization; the molecular weight of the polysaccharides can be reduced continuously and uniformly, and the degraded products with different molecular weight can be obtained by controlling the treatment conditions and the treatment time; the method is stable, and the reproducibility is good; and the requirement on equipment is low, and the operation is simple.
