Abstract

From the essential oil of Pulicaria gnaphalodes growing near Tehran some new cadinene derivatives were isolated. The structures of 1,8‐oxidocadin‐4‐enes (6, 7, epimers at C‐10), 1(10),4‐cadinadien‐8α‐ol (1), 4,10(14)‐cadinadien‐ and 4,10(14)‐muuroladien‐8‐ols (2–5) could be verified by their ^1^H‐ and ^13^C‐NMR spectra. Furthermore, the 8α‐epimer 9 of the known α‐copaen‐8β‐ol (10), (Z)‐γ‐curcumen‐12‐ol (13a) and the esters (Z)‐13b–e could be identified.

## Abstract From the essential oil of __Artemisia salsoloides__ the oxygenated monoterpenes 1, and 3–8 could be isolated. The easy formation of the hydroperoxide 2 from 1 suggests a biogenetic pathway from geraniol/nerol to 3. By comparison, the synthesized 8 exhibits mushroom and celery odor, typi
