In order to determine sodium chondroitin sulfate in the mixture, chondroitinase ABC was used for enzymatic reaction. The procedure was rapid, simple, quantitative and the HPLC analysis of <TEX>${\Delta}Di-6S$</TEX>(2-actamido-2-deoxy-3-0-(<TEX>${\beta}$</TEX>-D-gluco-4-enepyranosyluronic acid)-6-0-sulfo-D-galactose) in the sodium chondroitin sulfate was obtained. The absorbance was measured at 230nm and detection limit was <TEX>$1{\mu}g/ml$</TEX>. When we applied this method to the drugs(capsule, opthalmic solution), it gave the mean contents of <TEX>$100.01{\pm}1.58%$</TEX> and <TEX>$99.89{\pm}1.80%$</TEX> respectively.
