Tabernaemontana catharinensis: A Source of Indole Alkaloids With Potential Activity as Chemotherapeutic Agents

open access: yesChemistry &Biodiversity, Volume 23, Issue 4, April 2026.
ABSTRACT This study aimed to evaluate the antitumor activity of fractions rich in indole alkaloids extracted from the leaves of the species Tabernaemontana catharinensis. The chemical composition was analyzed using high‐resolution mass spectrometry (HRMS), which identified nine known indole alkaloids, including voacangine, voacangine hydroxyindolenine,
