摘要:

The oil from roots ofBowdichia virgilioides(Leguminosae) was analyzed by GC and GC/MS. The major constituents found were 2-tridecanone (54.6%), 4-ethyl-2-methoxyphenol (11.0%) and 2-pentadecanone (9.9%).

摘要:

The composition of the oils from leaves and flowers of three IranianAchilleaspecies(A. talagonicaBoiss.,A. vermicularisTrin andA. biebersteiniiAfan.) was analyzed by GC and GC/MS. During the flowering period, all three oils consisted mainly of monoterpenes. 1,8-Cineole and camphor were the predominant compounds in the oils ofA. talagonica(27% and 20%) andA vermicularis(29% and 32%) respectively. The major components of the oil ofA. biebersteiniiwere ascaridole (37%), piperitone (17%) and camphor (12%).

摘要:

The water-distilled volatiles of the the leaves ofPhyla scaberrima(L.) Small grown in Cuba were analyzed by GC/MS. Among the more than 35 compounds identified, β-caryophyllene (10.56%), 6-methyl-5-hepten-2-one (9.19%), bicyclogermacrene (9.00%) and δ-cadinene (8.65%) were the major constituents.

摘要:

Essential oils obtained with hydro- and microwave distillation from various plant parts were investigated with respect to yields and chemical composition. Only 21 known compounds were identified which account for less than 40% of the oil. 1,8-cineole was the major constituent among those identified in the flowerheads.

摘要:

The volatile constituents of the fruit pulp ofTamarindus indicaL. were isolated by steam distillation with subsequent extraction of the distillate with dichloromethane. The concentrated extract was analyzed by capillary GC and GC/MS. Sixty-six compounds were identified, furan derivatives and carboxylic acids were dominant, accounting for 44.4% and 33.3% of the total volatiles, respectively. The major components were furfural (38.2%), palmitic acid (14.8%), oleic acid (8.1%) and phenylacetaldehyde (7.5%).

摘要:

The essential oil ofAnthemis montanaL. (Asteraceae) has been analyzed using GC and GC/MS. Forty-two components were identified. The major fractions belonged to α-thujone (46.9%), β-thujone (16.0%), and trans-chrysanthemyl acetate (11.3%) amounting up to 74.2% of the total oil content.

摘要:

Water-distilled essential oil from the aerial parts ofOriganum haussknechtii, an endemic species in Turkey, was analyzed by GC/MS. One hundred components were characterized representing 91.5% of the total components detected. p-Cymene (15.56%) and borneol (14.24%) were the major constituents of the oil which was obtained in 0.24% yield.

摘要:

(Z)-β-ocimene has been found to occur in amounts of 85% in foliage ofHomoranthus montanusCraven and S. R. Jones and 69–71% inH. flavescensCunn. ex. Schauer. (E)-β-ocimene also occurred in amounts of 5–9% and 2–5% respectively. The oil yield in both cases was 0.3–0.5% based on fresh leaves.
