✦ Synopsis

The known diterpenes junceic acid (1) and the stress metabolite derivatives 2È4 were isolated from the hexane extracts of the roots of Croton sarcopetalus Muell. The complete 13C NMR chemical shift assignments of these compounds were achieved with the aid of DEPT and HETCOR experiments.

## Abstract An NMR study of one new and several known abietane diterpenes isolated from the roots of __Aegiphila lhotzkyana__ is described. In addition to 1D NMR, several 2D shift‐correlated NMR pulse sequences (^1^H–^1^H‐COSY, NOESY, HMQC and HMBC) were used to establish all the structures, and un
