Beschreibung
Zusammenfassung:	Disclosed are a low-molecular-weight chondroitin sulfate and a preparation method therefor. Macromolecular chondroitin sulfate is used as a raw material. A low-molecular-weight chondroitin sulfate having an average molecular weight of less than 1000 daltons can be obtained by means of a production process comprising chondroitin sulfate lyase degradation, deproteinization, filtration sterilization, drying, etc. With respect to the low-molecular-weight chondroitin sulfate, the molecular weight distribution range is narrow, the proportion of chondroitin sulfate disaccharide is 43％ to 60％, the proportion of chondroitin sulfate tetrasaccharide is 30％ to 45％, the sum of the contents of the chondroitin sulfate disaccharide and the chondroitin sulfate tetrasaccharide is greater than 87％, the total content of oligosaccharides in the low-molecular-weight chondroitin sulfate is not less than 97％, and the protein content is not more than 0.5％. Compared with common marketed macromolecular chondroitin sulfate, the product
