Shark-like chondroitin sulphate and process for the preparation thereof

摘要

The present invention concerns a shark-like chondroitin sulphate and a process for the preparation thereof. In particular, the present invention relates to a shark¬ like chondroitin sulphate, showing a very low amount of 4-sulphate, a high charge density and a biological activity comparable to natural chondroitin sulphates; the invention also relates to a process for the preparation of said shark-like chondroitin sulphate affording substantially higher productivities and better reproducibility of product quality. The shark-like chondroitin sulphate of the invention shows a high molecular mass and charge density; its in vitro biological and anti-inflammatory effectiveness, comparable to the ones of natural products make this polysaccharide potentially useful as a drug in pharmaceutical preparations and nutraceuticals.
