The essential oil of Pulicaria gnaphalodes (Vent.) Boiss. from Iran was investigated by GC, GCยฑMS and NMR spectroscopy. Typical for this oil are pinane [chrysanthenone (23), cis-chrysanthenol (34)], cadinane [cadina-1(10),4-dien-8a-ol (114)] and bisabolane derivatives [nuciferol (118), g-curcumen-12

โฆ Synopsis
The essential oil of Tanacetum (syn. Chrysanthemum) fruticulosum Ledeb. from Iran was investigated by GC, GCยฑMS and NMR spectroscopy. The oil is characterized by photo-oxidation products of lavandulol and nerolidol. Ninety-seven components, representing 93% of the oil, could be identiยฎed. The oil contains mainly monoterpenes [1,8-cineole (8), camphor (12), lavandulol (13), lavandulyl acetate ( 25)]. The new 5-isopropenyl-2,2-dimethyltetrahydrofuran-3-yl-methyl acetates (30, 31) are trace constituents. Some new farnesyl derivatives [3,6;6,9-bisepoxyfarnesa-1,7(14),10-trienes (43, 44, 48, 49), 7,10-epoxyfarnesa-1,5,11trien-3-ols (63, 64), 6,9-epoxyfarnesa-1,7( 14)10-trien-3-ols (80ยฑ83)] were identiยฎed by their NMR spectra.

The essential oil from the rhizomes of Hedychium gardnerianum Roscoe (`Kahili ginger') contains about 30% of sesquiterpenes, mainly cadinane derivatives. The following new sesquiterpenes were identiยฎed by their NMR and MS data: a-corocalene epoxide (104); 1,10;7,10-bisepoxy-1,10-seco-calamenene (68)

The composition of the essential oils of Nepeta ispahanica Boiss. and N. binaludensis Jamzad was investigated by means of GC, GCยฑMS and 1 H-NMR spectra of the main compounds. 1,8-Cineole was the most abundant component in both oils: Nepeta ispahanica (66%) and N. binaludensis (42%). However, nepetal
