摘要:

The composition of essential oil ofSatureja vimineaL. was analyzed by GC and GC/MS. More than 40 compounds were identified corresponding to ca. 94% of the oil. The major components were p-menth-3-en-8-ol (40.0%), pulegone (35.3%) and p-mentha-3,8-diene (5.2%).

摘要:

The essential oil of the foliage and branches ofSatureja vimineawas examined by GC and GC/MS. The oil, produced in 0.33±0.11% from fresh vegetative tops, was dominated by p-menth-3-en-8-ol (48.1±1.7%) and pulegone (14.4±1.3%).

摘要:

The leaf oils of the seven Australian and Lord Howe Island species ofZanthoxylumhave been investigated by GC and GC/MS. Apart from Z.ovalifolium, which had an oil yield of 1.1–1.9%, the remaining species had yields in the range trace-0.1%. The oil ofZ. brachyacanthumwas found to be rich in α-pinene (46.0%), β-caryophyllene (14.0%) and bicyclogermacrene (12.5%).Z. nitidum, which was sesquiterpenoid in nature, contained β-caryophyllene (11.0%) and α-humulene (7.2%) as principal components along with 2-tridecanone (7.7%) and an unidentified 2-alkanone (10.7%). One chemotype ofZ. ovalifoliumcontained α-pinene (31.6%) and myrcene (19.8%) as major components, while the other was rich in α-humulene (11.3%) and spathulenol (14.8%). InZ. parviflorum, the principal components were α-pinene (11.9%), β-elemene (8.6%), β-caryophyllene (23.4%) and caryophyllene oxide (11.7%). InZ. pinnatumfrom Lord Howe Island, 2-undecanone (54.3%) and 2-tridecanone (31.7%) were by far the major constituents. Unlike Indian oils from Z.rhetsa, the Australian material was sesquiterpenoid in nature with β-caryophyllene (27.5%) and germacrene D (18.4%) being major components. Z.veneficumoil was also sesquiterpene in nature with β-caryophyllene (36.3%), germacrene D (10.9%) and bicyclogermacrene (25.4%) being the principal components.

摘要:

The chemical composition of the hydrodistilled fruit oil ofBiota orientalis(L.) Endl, was examined by GC and GC/MS. Of the 25 constituents present in the oil, 17 were identified in which eight were monoterpene hydrocarbons (88.4%), four oxygenated monoterpenes (3.4%), three sesquiterpene hydrocarbons (2.1%), and two oxygenated sesquiterpenes (3.0%); α-pinene was the major constituents of the oil.

摘要:

The essential oils ofLippia alnifoliaSchau. andL.aff.gracillisH.B.K. from northeast Brazil were analyzed by GC/MS. Z.alnifoliaoil was found to contain limonene (47.2%) and piperitenone oxide (44.6 %) as major components. The oil of L. aff.gracilliscontained p-cymene (14.5%), γ-terpinene (10.6%) and carvacrol (38.4%) as dominant constituents.

摘要:

Twelve compounds were identified by GC/MS in the essential oil ofElyonurus muticusleaves, native in the Brazilian Pantanal. Spathulenol (18.6%), β-caryophyllene (17.9%) and camphene (11.5%) were the major components found in the oil.

摘要:

The essential oil ofCymbopogon citratus(DC.) Stapf. of Cuban origin has been analyzed by GC/MS. Twenty-seven compounds were identified of which neral (38.2%) and geranial (49.5%) were the major constituents.

摘要:

The chemical composition of the essential oils from the roots of plants identified asThapsia maximamorphological types I and II andT. villosadiploid types 1 and 2, tetraploid types 3 and 4 and hexaploid type 5 has been investigated by GC and GC/MS. The oils from the different specimens ofThapsiawere characterized by a high proportion of sesquiterpenoid components. The results are compared with those previously obtained from the fruits of the same plants.

摘要:

The essential oils obtained by hydrodistillation from feminine cones, leaves and branches of adultTaxodium distichumtrees have been studied by GC and GC/MS. Qualitative and quantitative differences have been detected among the three oils studied, in particular the essential oil of the feminine cones contained mainly monoterpene hydrocarbons with limonene (18.7%) and α-pinene (71.3%) being predominant. The leaf and branch oils were also rich in α-pinene (79.7% and 53.7%) in addition to more oxygenated monoterpenes and sesquiterpene hydrocarbons.
