RESUMEN
Phytochemical investigation of the 95% ethanol extract of the whole plant of Palhinhaea cernua afforded five new serratene-type triterpenoids (1-5) together with four known analogues (6-9). The structures of the new compounds were elucidated by extensive spectroscopic analysis and X-ray crystallographic data. Compounds 1-3 triggered apoptosis of Hela-/- cell with EC50 values of 3.49⯱â¯0.05, 0.28⯱â¯0.13 and 7.98⯱â¯0.03⯵M, respectively.
