摘要:

The chemical composition of Italian industrial mandarin petitgrain oil was examined using GC on two capillary columns and a fully automated “on-line” HPLC-GC/MS (ITD) system and a GC/MS (quadrupole) system. Methyl N-methyl anthranilate was found to be the main component representing about 50% of the whole oil. γ-Terpinene (23.9–28.5%) was the main monoterpene hydrocarbon, followed by limonene (7.2–12.6%) and p-cymene (3.0–5.2%). Alcohols were found to represent only about 1% of the oil, while aldehydes were present only as traces.

摘要:

Distilled Key lime oil (Citrus aurantifoliaSwingle) from Mexico has been analyzed by GC/MS and GC/FT-IR with cryofocusing capability. A total of 98 compounds have been identified. Thirty-three of these have not been reported previously for distilled Key lime oil. Quantitative data based on internal standard and response factors is presented for distilled lime oil and compared to cold pressed lime peel oil. Additional insights into the complex chemistry that takes place during distilled lime oil production are discussed.

摘要:

The essential oils isolated from threeGuatteriaspecies, Annonaceae (G. ouregouDun.,G. sagotianaR.E. Fries andG. wachenheimiBenoist) have been examined by GC and GC/MS. The main components of each oil (>5%) were:G. ouregouroot oil: caryophyllene oxide (24.8%), α-cadinol (11.4%), trans-carveol (8.4%) and spathulenol (5 7%);G. sagotianafruit oil: γ-terpinene (25.4%), p-cymene (24.9%), caryophyllene oxide (8.4%) and β-caryophyllene (7.4%);G. wachenheimistem bark oil: borneol (20.4%), δ-3-carene (19.9%), caryophyllene oxide (8.3%) and limonene (6.2%); andG. wachenheimileaf oil: β-caryophyllene (19.2%), caryophyllene oxide (12.3%), spathulenol (11.4%), α-humulene (8.8%) and borneol (8.4%).

摘要:

The leaf oil fromMelicope melanophloiaC.T. White indicates that it exists in three chemical forms. One form contains methyl chavicol (5–13%) and methyl eugenol (51–67%) as major compounds; a second form is entirely terpenoid with α-pinene (34–37%), myrcene, α-phellandrene, limonene and 1,8-cineole (4–12%) as major compounds; while a third chemotype contains limonene (1–8%), (Z)-β-ocimene (12–18%) and (E)-β-ocimene (23–56%) as major compounds. This third form also contains 2-hydroxy-4,6-dimethoxyacetophenone (4–6%). The oil yield from all chemotypes was in the range 0.1–0.9%.

摘要:

Collective and individual samples of myrtle leaf oil from Corsica were analyzed by GC, GC/MS and Carbon-13 NMR spectroscopy. Corsican myrtle was found to contain α-pinene (47.9–59-5%) and 1,8-cineole (19.8–28.1%) as major components. It belongs to the α-pinene/l,8-cineole chemotype.

摘要:

The essential oils obtained from roots of threeAngelicaL. species growing in France were analyzed by GC/MS. The dominant component in the root oil ofAngelica archangelicasubsp.archangelicavar.norvegica(Rupr.) Rikli, was δ-3-carene (13.0%), while the major component ofA. sylvestrisvar.elatiorWahlenb. root oil andA. heterocarpaLloyd root oil was nonane (18.7% and 5.2% respectively). One result of this study was that numerous volatile components found have never before been described as constituents of two of theAngelicaspecies examined. The chemical analyses present numerous systematic markers for each species and brings togetherA. sylvestrisandA. heterocarpa, in accordance with the biological observations.

摘要:

Eugenia uruguayensisleafoil, obtained by hydrodistillation, was analyzed by GC and GC/MS. Sixty components were identified in the oil. The main components were limonene (17.6%), 1,8-cineole (17.0%), α-pinene (10.0%) and caryophyllene oxide (8.3%).

摘要:

The chemical composition of essential oils of 16 samples ofArtemisia lerchianaWeber., collected in northeast Bulgaria has been analyzed by GC and GC/MS. The main components were found to be 1,8-cineole (1.8–45.5%), α-thujone (2.5–47.8%), β-thujone (0.0–34.5%), camphor (0.0–45.7%), borneol (0.0–16.0%), cis-sabinol (0.025.6%), davanone (0.0–38.3%) and β-cubebene (2.6–20.8%). The results revealed the existence of chemotypes within the investigated samples.
