Impact of Geographical Origin on the Contents of Inorganic Elements and Bioactive Compounds in Polygonum perfoliatum L.

This study investigated the correlation between thirteen inorganic elements, five key bioactive compounds, and environmental factors inPolygonum perfoliatumL. from fifteen different origins. Analyses were conducted using techniques such as ultrasound-assisted extraction, HPLC, ICP-AES, PCA, and HCA. The results indicate that the geographical origin significantly influences the contents of inorganic elements and bioactive compounds inPolygonum perfoliatumL., and a certain correlation exists among elements, compounds, and environmental factors. This research provides a theoretical foundation for the development and utilization ofPolygonum perfoliatumL.
