采用GC-MS法测定了大红袍和梅花椒鲜花椒和干花椒的最大挥发分，并进行了比较。在所有测试的样品中，芳樟醇、d-柠檬烯、桉油精、3-壬酮和β-月桂烯被确定为五种主要成分。新鲜大红袍中这些成分的含量分别为23.89%、21.04%、7.46%、5.63%和5.87%。干大红袍的比例相似，分别为 27.28%、17.62%、6.39%、1.66% 和 7.8%。总体而言，干大红袍和梅花椒中芳樟醇和β-月桂烯的含量略高于新鲜样品，而d-柠檬烯、桉油精和3-壬酮的含量较低。偏最小二乘判别分析结果表明，两个品种可以根据挥发物明显区分，而新鲜和干燥的花椒Maxim样品则不能。这表明干燥过程对挥发物没有显着影响。
Fresh and driedZanthoxylum bungeanumMaxim volatiles of two main cultivars includingDahongpaoandMeihuajiao, were determined through GC–MS and compared. In all the tested samples, linalool,d-limonene, eucalyptol, 3-nonanone, and β-myrcene were identified as the five predominant components. The percentages of these components in freshDahongpaowere 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%, were found in driedDahongpao. In general, the contents of linalool and β-myrcene in driedDahongpaoandMeihuajiaowere slightly higher than those in fresh samples, whereas the contents ofd-limonene, eucalyptol, and 3-nonanone were lower. Partial least squares discriminant analysis results showed that the two cultivars could be clearly differentiated based on volatiles, whereas, the fresh and driedZanthoxylum bungeanumMaxim samples could not. This demonstrated that the drying process had no significant effect on the volatiles.
