title: New macrocyclic diterpenoids from Jatropha multifida.
abstract: Chemical investigation on the stems of Jatropha multifida resulted in the isolation of two new macrocyclic diterpenoids whose structures were established by extensive studies of their 1D and 2D-NMR spectra. The occurrence of ten other known compounds in this species is reported here for the first time.
