摘要:

A steam-distillated essential oil (1% yield) obtained from the dried leaves ofPiper acutifolium(Piperaceae) was analyzed by capillary GC and GC/MS. The major constituents identified were: (E)-β-ocimene (8.1%), α-copaene (6.1%), allo-aromadendrene (6.0%), α-cadinene (6.7%), δ-cadinene (6.8%), myristicin (4.2%) and dillapiole (5.9%). The oil was evaluated for biological activity againstCallosobruchus maculatus(a stored grain insect pest). There was no effect on mortality; however, a significant decrease in oviposition was observed.

摘要:

The essential oil ofCymbopogon winterianusJowitt (Java citronella) of Cuban origin has been analyzed by GC and GC/MS. Thirty-six compounds were identified, of which citronellal (25.04%), citronellol (15.69%) and geraniol (16.85%) were the major constituents.

摘要:

Essential oils of six types ofLippia alba(Mill.) N.E. Brown, an aromatic shrub used in folk medicine in northeastern Brazil under the name “cidreira” were analyzed by GC/MS. The results showed neral (27.18–30.40%) and geranial (35.63–40.95%) as the main chemical constituent in three samples, while carvone (42.30–54.69%) was the main constituent in three other samples. These differences allowed for the classification of two chemotypes.

摘要:

Water-distilled oils ofMicromeria fruticosassp.giresunica, Sideritis lyciaandS. arguta, three endemic species to Turkey, were analyzed by GC and GC/MS. The main components of the oils wereM. fruticosassp.giresunica: pulegone (39.57%), menthol (24.27%) and menthone (24.21%);S. lycia:β-pinene (32.22%) and α-pinene (21.63%) andS. arguta:1,8-cineole (23.22%) respectively.
