    [Objective]To confirm the optimum extraction technology of essential oils from Glechoma longituba ( Nakai) Kupr on a pressure azeotropic distillation device. [Method]Taking the yield of essential oils as index,L9( 34) orthogonal test designed with 4 factors including soaking time ( A) ,solid-liquid ratio ( B) ,extraction time ( C) and NaCl concentration ( D) of each 3 levels was carried out to optimize the extraction technology of essential oils from G. longituba. [Result]The optimum technology for extracting essential oils from G. longituba was as follows: soaking time of 6 h,solid-liquid ratio of 1∶16 g/ml,extraction time of 4 h,and NaCl concentration of 0,under which the yield of essential oils could reach 0.03%. [Conclusion]The method is reliable,rapid and accurate,which could be used to extract essential oils from G. longituba.
