摘要：The conditions for microwave-assisted extracting oil from Zanthoxylum bungeanum seeds were studied and its chemical composition was analyzed by GC-MS. The effects of extract medium, microwave power, time and ratio of liquid to solid on extraction yield of Zanthoxylum bungeanum oil were investigated, using an orthogonal array design. The experimental results showed that using petroleum ether as extract medium, microwave power 350 w, solid-to-solvent ratio 1:5 (g/mL), 60 sec, can obtained 7.85% of Zanthoxylum bungeanum oil. Thirty-three substances in Zanthoxylum bungeanum oil were authenticated by GC-MS, of which 33 were identified for the first time and its chemical composition was analyzed. Accounting for 97.82% of the total volatile compounds.
