Comparison of metabolome characteristics and screening of chemical markers in from different habitats.

UNLABELLED

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.
