Two new glycerol esters, (S)-2-hydroxy-3-(octanoyloxy)propyl tetracosanoate (1) and (S)-3-(((S)-11-acetoxy octadecanoyl)oxy)propane-1,2-diyl diacetate (2), and eight known compounds, docosanedioic acid (3), 2,5-dimethylnonadecane (4), lupeol (5), stigmasterol (6), βsitosterol (7), heptadecanoic acid (8), hexanedioic acid, 1,6-bis[(2R)-ethylhexyl] ester (9), and 10) were isolated from the leaves of Garcinia daedalanthera Pierre, collected from Indonesia. Structural analysis of the isolates was performed using 1D-and 2D-NMR, LC-and GC-MS, IR, polarimetry, and UV-visible spectroscopic methods.Cytotoxicity assessments, as well as reactive oxygen species (ROS) analysis of the isolates, were also completed. Lupeol was the only compound found active with an IC 50 value of 19.2 µM against HT-29 colon cancer cells. Significant ROS inhibition and induction activity was observed for compounds 4 and 8, respectively.
