Abstract
The optimum process condition of extracting zanthoxylum bungeanum oil by subcritical extraction technology was determained by single-factor test.The impacts of the granularity of bunge pricklyash seeds,the extraction time and frequency on the yield of the zanthoxylum bungeanum oil were discussed.The result showed that the best extraction efficiency of the zanthoxylum bungeanum oil were obtained with the granularity of 40,the temperature of extraction 40℃,extraction twice for 30 min.
