摘要:

The essential oil from the bark of balsam firAbies balsamea(L.) Mill, which was obtained by hydrodistillation (3 h) was analyzed by GC and GC/MS. The major constituents obtained were: α-pinene (25.8%), β-pinene (27.3%), β-phellandrene (23.1%) and limonene (9.2%). Twenty-one minor components were also identified. The yield of oil relative to fresh bark varied between 0.43% and 0.45% (w/w).

摘要:

The essential oil ofMentha citrataEhrh. plants collected in full bloom and at the post-flowering stage, were analyzed by GC and GC/MS. Fourteen main components representing more than 90% of the total oil were identified, the main components being linalool (23.8–35.4%) and linalyl acetate (48.7–60.9%).

摘要:

Volatile constituents of ripe boysenberry (Rubussp. hybrid) fruit were isolated by vacuum steam distillation and analyzed by GC and GC/MS. Thirty-two compounds were identified, 15 for the first time as volatile constituents of boysenberry. The major volatiles were ethanol (54.1%), linalool (23.7%) and α-terpineol (5.1%). Linalool, α-terpineol, nerol and geraniol were judged primarily responsible for the ‘boysenberry-like’ character of the ripe fruit.

摘要:

Essential oils ofArtemisia afraJacq. were produced by hydrodistillation of either fresh or dried whole plants that were raised in Vienna from seed of Ethiopian origin. Oils were produced from plants that were harvested prior to bud formation, during budding and during full flowering. The six major components of the oil, which represented ca. 70% of the total oil composition, were determined by GC/MS. Yomogi alcohol (21.6 - 26.8%) and artemisyl acetate (24.4–32.1%) predominated in each of the oils, the compositions of which appeared to be independent of plant maturity.

摘要:

The essential oil from the aerial parts ofAdenosma glutinosum(L.) Druce var.caeruleumTsoong (Scrophulariaceae) was analyzed by a combination of high resolution GC and GC/MS. More than 35 constituents have been identified, of which the major ones were α-pinene (22.7%), 1,8-cineole (18.2%) and γ-terpinene (16.9%).

摘要:

The essential oil of two wild plants from Corsica,Calamintha nepetasubsp.glandulosaandCalamintha nepetasubsp.nepeta, were analyzed by Carbon-13 NMR spectroscopy and GC. The most frequent chemotype was menthone/pulegone. However, the menthone/pulegone ratio varies greatly according to the sample studied and the vegetative state of the plant.

摘要:

The leaf essential oils ofJuniperus phoeniceaL. (Greece and Spain),J. phoeniceasubsp.eu-mediterraneaLebr. & Thiv. andJ. phoeniceavar.turbinata(Guss.) have been analyzed by GC/MS. All of the oils were dominated by α-pinene.Juniperus phoeniceaalso contained moderate amounts of myrcene, limonene, β-phellandrene, α-terpinyl acetate and 1-epi-cubenol. The oils ofJ. phoeniceavar.turbinata(coastal Spain) andJ. phoeniceasubsp.eu-mediterranea(coastal Portugal) are most similar of the four taxa and distinct from typical inlandJ. phoenicea.These taxa may be conspecific and, if so, then the nameJ. phoeniceavar.turbinatawould take precedence for the divergent taxon.

摘要:

Volatile compounds fromColeus aromaticusBenth. leaf were isolated by steam distillation, hexane extraction and supercritical CO2extraction. The yield obtained from steam distillation was 0.55%, from hexane extraction 6.52%, and by supercritical CO2extraction 1.40%. The difference in aroma of the extracts was quite noticeable and can be attributed to qualitative and quantitative differences of the components. Twenty-six components were identified by GC/MS, eleven for the first time.

摘要:

The chemical composition of the essential oil from branches and leaves of different provenances ofPinus nigraArn. was determined by GC/MS. The composition of essential oils has been found to vary depending upon the plant part from which it was obtained and the geographical origin. The results of this study showed that oils fromPinus nigraArn. can be valuable for industrial purposes. The branch oil contained α-pinene (58.8%) as the major constituent, whereas the needle oil contained α-pinene (21.4%) and 1-epibicyclosesquiphellandrene (30.4%).
