Abstract
From trunk heartwood of Plathymenia reticulata (Leguminosae) two novel cassane diterpenes 16,18-diacetoxycass-13(15)-ene and 16-hydroxy-18-acetoxycass-13(15)-ene, and the known diterpenes plathyterpol, vinhaticyl acetate and methyl vinhaticoate were isolated. Structure determinations were accomplished by spectroscopic analysis involving comparison with data from literature and chemical transformations.
