Objective To investigate a quick and simple method for determination of chondroitin sulfate in health foods by high performance liquid chromatography (HPLC). Methods Samples were treated using 0.005 mol/L pentane solution of sodium-acetonitrile as mobile phase with isocratic elution, separated on diamonsil C18 column, and detected at 192 nm wavelength. Results Chondroitin sulfate could be separated well by this method. It had a good linear relationship within 0.008~0.04 mg/mL (r=1.000), the average recoveries was 98.5%~100.0%, and the RSD was 0.6%. Conclusion The method can be used for determination of chondroitin sulfate in health foods, it is quick, simple and accurate, and has a good reproducibility and clear separation, which can be popularized in the laboratory.
