29-Norcucurbitacin derivatives isolated from the Indonesian medicinal plant, Phaleria macrocarpa (Scheff.) Boerl.
The new 29-norcucurbitacin, desacetylfevicordin A (1), together with three known 29-norcucurbitacin derivatives (2-4) were isolated from seeds of the Indonesian medicinal plant, Phaleria macrocarpa (Scheff.) Boerl. The structures of 1-4 were elucidated on the basis of spectroscopic analyses and chemical transformation. These compounds exhibited toxicity against the brine shrimp (Artemia salina).
