摘要:

The steam-distilled oil ofSalvia officinalisL. grown in Reunion Island was analyzed by GC, GC/MS and GC-FTIR. The oil was found to contain 51 compounds, the major ones being α-thujone (43-3-45.5%) and β-thujone (8.4-8.8%), camphor (15.9-16.2%) and 1,8-cineole (5.8-8.3%).

摘要:

A steam distilled oil obtained from the fruits ofAstydamia latifoliagrown in Tenerife, Canary Islands, was analyzed by GC and GC/MS. Twenty-six components were characterized representing 98.6% of the oil. The oil contained β-phellandrene (15.0%), γ-terpinene (6.0%), myristicin (39.6%) and dillapiole (16.9%) as major constituents.

摘要:

The essential oil from the aerial parts ofTanacetum vulgareL. was analyzed using GC/MS. Of the 20 constituents identified, six were monoterpene hydrocarbons (3.9%), 10 oxygenated monoterpenes (81.9%), one sesquiterpene hydrocarbon (1.7%), two phenolic compounds (3.0%) and a long chain hydrocarbon (1.5%). The oil belongs to the thujone (66.8%) chemotype. (+)-10 Hydroxy-3-thujone was characterized using NMR methods.

摘要:

The γ-lactones found in white cypress-pine(Callitris glaucophylla)wood are compounds implicated in termiticidal activity. Distilled oils and solvent extracts from an cypress-pine contained different amounts of γ-lactones. The distilled oils were poor in γ-lactones (<10%) while solvent extracts were rich in these compounds (>45%). Oils and extracts contained (-)eudesma-1,4(15),11-triene, β-selinene and α-selinene previously found in otherCallitrisoils. Six γ-lactones were identified using GC/MS. They were callitrin, dihydrocolumellarin, callitrisin, columellarin, germacranolide and dihydrocallitrisin. Mass spectroscopy indicated three previously unidentified lactones; two were isomers of callitrisin and the third, an isomer of germacranolide. Chiral gas chromatography separated many enantiomers of lower boiling point components of the distilled oil.

摘要:

The chemical composition of the essential oil ofPiper permucronatumYuncker from Rio de Janeiro, Brazil was analyzed by GC and GC/MS. The oil consisted mainly of sesquiterpenes and a small percentage of monoterpenes. A total of 33 compounds were identified. The major components found in the oil were δ-cadinene (12.7%), γ-muurolene (7.4%), α-cadinol (6.9%), β-caryophyllene (6.8%), T-muurolol (32%), α-muurolene (2.9%) and γ-elemene (2.7%).
