| Abstract: | Asteriscus graveolens is an endemic medicinal plant mainly distributed in south‐western Algeria and south‐eastern Morocco. The essential oils of leaves, stems, and flowers of A. graveolens had been studied by GC, GC/MS, and 13C‐NMR. The spectral data of two nerolidol derivatives, 6‐oxo‐ and 6‐hydroxycyclonerolidol, were reassigned by 1D‐ and 2D‐NMR spectroscopy. These compounds can be considered as chemical markers of this genus. The structure of a monoterpenic diester with a chrysanthenane skeleton, i.e., cis‐8‐acetoxychrysanthenyl acetate, was determined for the first time on the basis of GC/MS, and 1D‐ and 2D‐NMR. The stem and leaf oils were characterized by high content of oxygenated sesquiterpenes with 6‐oxo‐ and 6‐hydroxycyclonerolidol as major components, and the flower essential oils were dominated by the new monoterpenic compound cis‐8‐acetoxychrysanthenyl acetate. |
