RESUMEN

Four new crotofolane-type diterpenoids, crotocarasin (A-D) (1-4), together with the known crotofolin E, were isolated from a dichloromethane extract of the stems of Croton caracasanus Pittier. The structures of the new compounds were determined by spectroscopic methods, and the structure of 3 was further confirmed by single-crystal X-ray data analyses.
