RESUMO
The dichloromethane extract of Cespitularia erecta afforded a new verticillane diterpenoid (1) and sarcophytol A (2) by silica gel chromatography. The structure of 1 was elucidated by extensive 1D and 2D NMR spectroscopy.

RESUMO
The dichloromethane extract of Xenia viridis afforded two new xenicane diterpenoids (3 and 4) by silica gel chromatography. The oxirane ring of 3 was found to be susceptible to a slow ring opening under acidic conditions to afford 5. Their structures were elucidated by extensive 1D and 2D NMR spectroscopy.
