Fresh cockscomb was used as the raw material and the hyaluronic acid extraction yield as the target to withdraw the method by ethanol precipitation .The ranges of all affecting factors were determined by single factor experiment and Box -Behnken center combination experimental design used to set up two times multiterm mathematical model .The result indi-cated that the data results significantly and the optimum conditions of ethanol precipitation was obtained as follows: the extraction time was 25.70 h, hyaluronic acid extraction yield was 90.00%,solid-liquid ratio was 100∶177 ( g/mL) and the hyaluronic acid extraction yield was 23 .73%.Determine the extraction of substances through the UV spectrum detection of hyaluronic acid .
