Secondary metabolites from Pierre leaves (Clusiaceae).

Two new glycerol esters, ()-2-hydroxy-3-(octanoyloxy)propyl tetracosanoate () and ()-3-((()-11-acetoxy octadecanoyl)oxy)propane-1,2-diyl diacetate (), and eight known compounds, docosanedioic acid (), 2,5-dimethylnonadecane (), lupeol (), stigmasterol (), β-sitosterol (), heptadecanoic acid (), hexanedioic acid, 1,6-bis[(2)-ethylhexyl] ester (), and 1,3-di--[2',2'-di-(-phenylene)] () were isolated from the leaves of 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.
