The invention relates to a low molecular weight sulfate chondroitin and a preparation method thereof. A low molecular weight chondroitin sulfate with the average molecular weight of less than 1000 Dalton can be obtained by a production process of chondroitin sulfate lyase degradation, deproteinization, filtration and sterilization and drying using macromolecular sulfate chondroitin as a raw material. The low molecular weight Chondroitin sulfate has a narrow molecular weight distribution range, the ratio of chondroitin sulfate disaccharide is 43˜60% and the ratio of chondroitin sulfate tetrasaccharide is 30˜45%, the sum of chondroitin sulfate disaccharide and chondroitin sulfate tetrasaccharide is more than 87%, the total oligosaccharide content of low molecular weight chondroitin sulfate is more than 97% and the protein content is less than 0.5%; Compared with the general market macromolecule chondroitin sulfate, the product has more remarkable repair effect at the concentration of 50˜100 μg/mL on chondrocytes damaged by 1 mM hydrogen peroxide, with strong repair ability and repair rate of 14%˜23%. The low molecular weight chondroitin sulfate can be used to treat joint injury and is an important raw material for medical products, health care products, cosmetics and food.

A composition comprising, as an active ingredient, a cell body of a fig-derived lactic acid bacterium belonging to Lactobacillus paracasei, a cultured or fermented product thereof, or a polysaccharide produced thereby is effective in improving, preventing or treating an inflammatory bowel disease and can be particularly used as a food or drink, a medicament or a feed for improving, preventing or treating ulcerative colitis or Crohn's disease.
