Resumo

Abstract Two novel casbane diterpenes 1‐hydroxy‐(2 E ,6 Z ,12 E )‐casba‐2,6,12‐triene‐4,5‐dione (1) and 6 E ,12 E ‐casba‐1,3,6,12‐tetraen‐1,4‐epoxy‐5‐one (2) were isolated from the ethanol extract of the stems of Croton argyrophyllus . Structural characterization including the relative stereochemistry of all compounds was established on the basis of spectroscopic methods, mainly 1D and 2D NMR, and HRESIMS.
