title: [Zymohydrolysis with chondroitinase ABC and high performance liquid chromatography used for the determination of hyaluronic acid in shark fin].
abstract: A method for the determination of hyaluronic acid in shark fin by high performance liquid chromatography (HPLC) is described. At 37 degrees C, with 0.2 mol/L Tris-HCl buffer solution, hyaluronic acid was converted to the hyaluronic acid disaccharide by zymohydrolysis with chondroitinase ABC. The chromatographic conditions were as follows: ZORBAX carbohydrate analysis column (4.6 mm i.d. x 250 mm, 5 microns); room temperature; UV-VIS detector set at 226 nm; mobile phase V(acetonitrile): V(0.5% phosphoric acid) = 2:98; 0.45 micron filter membrane, pumping filter; injection volume 10 microL; flow rate 1 mL/min. The calibration curve for the hyaluronic acid disaccharide was linear over the range of 25 g/L-600 g/L. This method was applied to the analysis of shark fin with satisfactory results. The hyaluronic acid contents in different shark fins were from 0.86% to 1.96%.
