Abstrakt: Jiaogulan herbal tea, known for its pharmacological benefits, is derived from various species within the genus Gynostemma, particular for G. pentaphyllum (GP) and G. longipes (GL). Herein, a global approach integrating chemometrics with qualitative and quantitative methods was utilized to investigate the chemical profiles and variations in GP and GL from different geographic origins. A total of 227 triterpenoid saponins were identified in two Gynostemma species, among which 23 differential markers ware screened out by multivariate statistical analysis. Furthermore, the contents of significant markers were determined after the demalonylation process. The chemical composition of GP samples sourced from diverse regions were firstly summarized into three chemotypes (I-III), along with an additional chemotype (IV) for GL. This study contributes to a deeper understanding of Gynostemma plants and provides valuable theoretical basis for the quality control in the production of Jiaogulan herbal tea.
