The known diterpenes junceic acid (1) and thestress metabolite derivatives 2–4 were isolated from the hexaneextracts of the roots of Croton sarcopetalus Muell. Thecomplete 13 C NMR chemical shift assignments of thesecompounds were achieved with the aid of DEPT and HETCOR experiments.© 1998 John Wiley & Sons, Ltd.
