Tang Xianjue, et al. Preparation and Determination of Chondroitin Sulfate[J]. Journal of Chongqing Medical University, 1999,(4):374-376. DOI: 10.13406/j.cnki.cyxb.1999.04.013.
Preparation and determination of chondroitin sulfate from pig cartilage was described.This method is asimpler process with lower cost and 14% higher yield (by weight of cartilage). The content of chondroitin sulfate(about 70%) was determined by complexometric titration. The accuracy of determination was studied.
