The performance and purpose of abietic acid was introduced in the paper, as well as the property and advantage of microwave heat, technological process of abietic acid extraction from colophony under microwave radiation. The effect of power, time used of microwave radiation and amount of catalyzer on abietic acid extraction were also discussed. Under microwave radiation, the optimum condition for extracting abietic acid can be found. The optimum reaction condition of this technological process was obtained from experiment: 1.2mL of HCl as catalyzer; 616W of microwave power; 40min of microwave radiation time. Abietic acid product of 20.1% of recovery , 170℃ of melting point and -103.8 of specific rotation was obtained from testing that was implemented on basis of all optimized factors.
