Zanthoxylum bungeanum Maxim. is widely distributed across China, and the aroma of its peel is primarily determined by its volatile components. In this study, we analyzed the characteristics of volatile components in Z. bungeanum peels from different regions and investigated their correlation with climatic factors.
The results identified 126 compounds in Z. bungeanum, with 27 compounds exhibiting distinct odor characteristics. Linalool was the most abundant, with an average relative content of 21.664%. The volatile oil of Z. bungeanum predominantly features spicy, floral, citrus, and mint aromas. The classification results indicated a significant difference in elevation at the ZB10 collection points in Shaanxi Province compared to other groups. Temperature, average annual precipitation, and wind speed were crucial factors influencing the accumulation of volatile components.
This study is beneficial for enhancing the quality of Z. bungeanum, expanding the understanding of how climatic factors influence the accumulation of volatile substances, and promoting agricultural practices in regions with similar climatic conditions.
花椒在中国广泛分布，其果皮的香气主要由其挥发性成分决定。本研究分析了不同地区花椒果皮挥发性成分的特征，并探讨了其与气候因素的相关性。
鉴定出花椒中含有 126 种化合物，其中 27 种具有明显的气味特征。芳樟醇含量最高，平均相对含量为 21.664%。花椒挥发油主要呈现出辛辣、花香、柑橘和薄荷香气。分类结果表明，陕西 ZB10 采集点的海拔与其他组有显著差异。温度、年平均降水量和风速是影响挥发性成分积累的关键因素。
本研究有助于提高花椒的品质，加深对气候因素影响挥发性物质积累的认识，促进类似气候条件地区的农业实践。
