Abstract
Background
Zanthoxylum bungeanum Maxim. is widely distributed in China, and the aroma of Z. bungeanum peel is mainly determined by volatile components. In this study, the characteristics and correlation of volatile components of Z. bungeanum peels in different regions and their correlation with climate factors were analyzed.
Results
The results showed that 126 compounds were detected in Z. bungeanum. Among the 27 compounds with odor characteristics, the one with highest content was Linalool, and the average relative content was 21.664%. The volatile oil of Z. bungeanum mainly presents a spicy, floral, citrus and mint aroma. The classification results were geographically continuous, with the ZB10 collection site in Shaanxi showing significant differences in altitude compared to other groups. Temperature, average annual precipitation, and wind speed played an important role in the accumulation of volatile components.
Conclusions
This study is helpful to improve the quality of Z. bungeanum, enrich the influence of climate factors on the accumulation of volatile substances, and promote agricultural practices in regions with similar climatic conditions.
