Chemistry &Biodiversity, Volume 23, Issue 10, October 2026.Artichoke bract polyphenols, particularly from inner bracts, are rich in 1,4‐dicaffeoylquinic acid and chlorogenic acid. In oleic acid‐induced HepG2 cells, these polyphenols activate AMPK and modulate PPARγ signaling, reducing lipid accumulation. These findings highlight the potential of artichoke bracts, including agricultural waste outer bracts, as ...

Recent Advances in Biosynthesis and Bioactivity of Plant Caffeoylquinic Acids
Current Issues in Molecular BiologyCaffeoylquinic acids (CQAs), a class of phenolic acid metabolites widely distributed in plants, encompass 15 positional isomers from mono- to tetra-esters, with 5-O-caffeoylquinic acid (5-CQA) as the predominant form. The biosynthesis of 5-CQA from phenylalanine proceeds through five primary pathways, which are finely regulated by environmental ...
