is a polymorphic species with many ecological, geographical or eco-geographic populations, but there are few studies on the metabolic characteristics of different populations. This study conducted widely targeted metabolomics studies on from seven typical producing areas. As a result, a total of 802 metabolites were detected and identified, among which the top three categories of metabolites were flavonoids, organic acids and amino acids and derivatives. Through multivariate statistical analysis, the seven samples from different habitats could be divided into four categories, and the significantly changed metabolites between different categories were mainly concentrated in the flavonoid synthesis pathway. Through a variety of cluster analysis, it was observed that the (Nakai) Tzvel (Chinese name Juhuanao) had the largest separation degree from other samples and were clustered into a single category. Furthermore, the corresponding candidate chemical markers were screened in this study to distinguish the Juhuanao. Correlation analysis showed that climatic factors were not the main reason for the differences in the metabolic characteristics of in different populations, which indicated that is indeed a species with rich variation.

是一个具有许多生态、地理或生态地理种群的多态物种，但关于不同种群代谢特征的研究较少。本研究对来自七个典型产地的 进行了广泛靶向代谢组学研究。结果，共检测并鉴定出802种代谢物，其中代谢物的前三大类为黄酮类、有机酸类和氨基酸及其衍生物。通过多元统计分析，来自不同产地的七个样本可分为四类，不同类别之间显著变化的代谢物主要集中在黄酮类合成途径。通过多种聚类分析，观察到（中名巨花凹）与其他样本的分离度最大，并聚为一类。此外，本研究筛选了相应的候选化学标志物以区分巨花凹。相关性分析表明，气候因素不是不同种群 代谢特征差异的主要原因，这表明 确实是一个具有丰富变异的物种。
