Verbena oil

An acyclic monterpene, b.p. 166-168°C, found in many essential oils, e.g. in verbena oil and oil of hops. [Pg.268]

Bark beetles of the genus Ips are pests which attack pine and spruce trees. They use ipsdienols as aggregation pheromones, Ips confusus emitting the (5)-(-l-)-, and Ips paraconfusus the (.K)-(-)-enantiomer The beetles receive the myrcenes (section 2.2) occurring in conifers with their food and metabolize them to ipsdienols some evidence for de-novo synthesis by the bugs is also reported. In order to catch the beetles, pheromone traps are supplied with both enantiomers of ipsdienol which are produced from (-l-)-verbenone, a constituent of the Spanish verbena oil (section 2.4.3). This terpenone, also available by oxidation of a-pinene, is isomerized to the enantiomers of 2(10)-pinen-4-one via three steps (reduction, protonation, oxidation). After separation, both enantiomers are reduced by lithiumaluminumhydride. Pyrolytic cycloreversion of the resulting diastereomeric 2(10)-pinen-4-ols provides the enantiomers of ipsdienol... [Pg.127]

Lemon-grass (so-called verbena) oil, distilled from the grass An-dropogon citratus, which is grown in India and, more recently, in the West Indies. The oils from these two sources differ somewhat in their properties, and also in value, the former being preferred on account of its greater solubility in alcohol. [Pg.102]

The diastereoisomeric 2-isopropenyl-5-methylcyclopentane carbalde-hydes (101), (102) and (103) as well as l,6,6-trimethylbicyclo[2.1.1]-hexane-5-carbaldehyde (104), which result from the photocyclization of citral (92), were described as important constituents of verbena oil 280). Photocitral A (707), the scent of which is described as fresh, camphor-like, green and herbal, is responsible for the typical top note of verbena oil and is, therefore, the most important member among the four photocitrals present in the oil (279). The odor qualities of e/ /-photocitral A (102) are similar, though milder, whereas trans,trans-photocitral (103) is characterized by a more fruity, resinous and woody... [Pg.466]

Caryophyllan-2,6-P-oxide (221) which has a woody-balsamic odor (275) contributes to the pleasant body of verbena oil (257). [Pg.481]

A warm woody, amber-like note of relatively low strength is also said to be characteristic of kobusone (239) 325). This epoxyketone was one of the substances found in verbena oil 280). [Pg.484]

The so-called Spanish verbena oil is derived from a Labiate plant. [Pg.271]

Verbena oil is rarely soluble in either 70 or 80 per cent alcohol. [Pg.271]

The principal odorous constituent of the oil is citral. Theulier has identified geraniol, l-limonene, a sesquiterpene, and a paraffin hydrocarbon mdting at 62 5. Myrcene has b n reported as present, but the ofl examined was probably lemon-grass and not true verbena oil Eerschbaum has made an exhaustive examination of the genuine oil and has isolated therefrom an aldehyde which he has named... [Pg.271]
