英文摘要：

Objective Studying the extraction process of Periplaneta americana oil and determining the saponification value, toprovide scientific basis for the future oil determination,exploitation and utilization. Methods： With petroleum ether as the solvent, theeffects of extraction material ratio, temperature and time on the extraction rate and the saponification value were investigated byorthogonal experiment. Results： When using the method of cable extraction, the optimum conditions for Periplaneta americana lipidextraction were： extraction ratio of material to solvent： 1：15, temperature： 80 ℃, time： 2 h. Conclusion： Verification experimentalresults show that the method is simple and accurate, which can be used as a method for the extraction of Periplaneta americana oil.
