Fresh and dried Zanthoxylum bungeanumMaxim volatiles of two main cultivars including Dahongpaoand Meihuajiao, were determined through GC–MS andcompared. In all the tested samples, linalool, D-limonene,eucalyptol, 3-nonanone, and b-myrcene were identified asthe five predominant components. The percentages of thesecomponents in fresh Dahongpao were 23.89%, 21.04%,7.46%, 5.63% and 5.87%, respectively. Similar percentages,27.28%, 17.62%, 6.39%, 1.66% and 7.8%, werefound in dried Dahongpao. In general, the contents oflinalool and b-myrcene in dried Dahongpao and Meihuajiaowere slightly higher than those in fresh samples,whereas the contents of D-limonene, eucalyptol, and3-nonanone were lower. Partial least squares discriminantanalysis results showed that the two cultivars could beclearly differentiated based on volatiles, whereas, the freshand dried Zanthoxylum bungeanum Maxim samples couldnot. This demonstrated that the drying process had nosignificant effect on the volatiles.
