In this work, the extraction of astaxanthin i.e. bioactive substance in the shrimp head and shell was studied. The extraction method of astaxanthin was established: the alkali method and organic solvents method were combined to extract astaxanthin, the solvent of the alkali solution was ethanol:water =4:1, dichloromethane was selected as the extractant. The best extraction conditions for astaxanthin were optimized: the concentration of sodium hydroxide was 1.4mol / L, the optimum extaction process was at 54°C for 24 h, and the ration of solid to liquid was 8:1. In this condition, the absorption value of astaxanthin was 1.2048, the concentration of astaxanthin was 3.26μg/mL, which was equivalent to 32.6 μg/g dry shrimp shell.
