“…The latter two components were not found in the other oils and their isolation, identification and importance to the odor impact of this oil is reported in another paper (3). This oil is very complex, containing the three eudesmol isomers (1.7% total) together with caryophyllene oxide (1.0%) and spathulenol (1.7%).…”

Publication details, including instructions for authors and subscription information:ABSTRACT: The composition of essential oil from Olearia phlogopappa clones collected from six locations in Tasmania was analyzed by GUMS. The major components identified were j3-caryophyllene, bicyclogermacrene, germacrene-D, liguloxide, kessane, caryophyllene oxide, spathulenol and a-, j3 and y-eudesmols. The clonal variation in oil composition and odor is also described.

“…[230] Its structure including absolute configuration was established by correlation with known α-kessyl alcohol (103) [231] that was converted into 99 by tosylation and treatment with LiAlH 4 (Scheme 27B), [230] and by enantioselective synthesis from (+)-aromadendrene. [232] Kessane (99) was later isolated again from Senecio, [233][234][235] Bothriochloa intermedia, [40] Prostanthera ovalifolia, [179] Olearia phlogopappa [236] and Machaerium multiflorum. [237] Two sequential 1,2-hydride shifts via Q4 to R5 and ring closure give rise to (À )-liguloxide (100) from Ligularia ([α] D = À 52.8).…”

The known sesquiterpenes that arise biosynthetically from hedycaryol are summarised. Reasonings for the assignments of their absolute configurations are discussed. The analysis provided here suggests that reprotonations at the C1=C10 double bond of hedycaryol are directed toward C1 and generally lead to 6–6 bicyclic compounds, while reprotonations at the C4=C5 double bond occur at C4 and result in 5–7 bicyclic compounds.

The leaf oil of Ferula arrigonii Bocchieri was investigated using combination of GC, GC/MS and 13C‐NMR spectroscopy. After fractionation by column chromatography, 56 components were identified, representing 97.0% of the total amount of the oil. The main constituents were β‐phellandrene (16.6%), germacra‐1(10),5‐dien‐11‐ol (15.4%) and linalool (12.5%). 13C‐NMR appeared to be a powerful tool for sesquiterpene identification.
