Impact of Species, Growth Conditions, and Plant Processing on the Phytochemistry and Antimicrobial Activity of Agrimonia Extracts

Chemistry &Biodiversity, EarlyView.
Agrimony is a medicinal herb known for its content of polyphenols and beneficial bioactivity, both of which can be strongly influenced by cultivation and processing. This study reveals that agrimony plant structures, species, and postharvest processing are the main drivers of observed variability in both phytochemical composition and antimicrobial ...
