Three furano-diterpenes have been isolated from the dichloromethane ex
tract of Croton campestris St Hil. roots. Their structures have been e
stablished by spectroscopic methods. The compounds were named velamone
(ent-15,16-epoxy-2-oxo-3,13(16),14-clerodatrien), velamolone (ent-15,
16-epoxy-20-hydroxy-2-oxo-3,13(16), 14-clerodatrien) and velamolone ac
etate -epoxy-20-acetoxy-2-oxo-3,13(16),14-clerodatrien). (C) 1998 Else
