Metabolomic Differentiation of Malpighiaceae From Dry and Humid Tropics via UHPLC‐MS/MS and Chemometrics

open access: yesAnalytical Science Advances, Volume 7, Issue 1, June 2026.
ABSTRACT Various factors can trigger water stress in plants, particularly in those growing in dry tropical regions. To survive under such conditions, plants produce metabolites with adaptive functions. However, metabolomic data on the leaves of Malpighiaceae species cultivated in both dry and humid tropical areas of Brazil remain scarce.
