Comparative Metabolite Profiling of Three Savannic Species of Banisteriopsis (Malpighiaceae) via UPLC‐MS/MS and Chemometric Tools

Chemistry &Biodiversity, Volume 21, Issue 11, November 2024.
Abstract Banisteriopsis (Malpighiaceae) is an important genus of neotropical savannas with related biological and medicinal activities but under‐explored metabolomic profiles. We present a chemometric analysis for discriminating secondary metabolites of three species of Banisteriopsis (B. laevifolia, B. malifolia, and B. stellaris) leaves.
