Abstract: A high performance liquid chromatographic method was established for the determination of hydroxyproline in fishery products with pre-column derivatization. Samples were hydrolyzed with hydrochloric acid before pre-column derivatization with dansyl chloride. The analyze was separated using a C18 column and detected using a UV detector. Good separation was achieved for hydroxyproline and other amino acids. The linear range was 0.5-20 μg/mL (r > 0.9999). The detection limit was 0.5 μg/mL. The average spike recovery rates were 80.2%-103% with a RSD of 3.2%-5.6%. The method was sensitive, accurate and suitable for the determination of hydroxyproline in fishery products.

Key words: hydroxyproline, dansyl chloride, pre-column derivatization, HPLC, fishery products
