Cymbopogon .species

Essential oil analyses of note this year are of Buchu leaf (some p-menthane sulphur derivatives), Hyssopus officinalis (methyl myrtenate, 2-hydroxyisopinocamphone, pinic acid, and pinonic acid), Laggera aurita (m-menth-6-en-8-ol), some Cymbopogon species (up to 89% of unusual p-menthadienols), and Trichostema lanceolatum (55% p-menthen-4-ol). There... [Pg.9]

Citronellal is a monocyclic monoterpene aldehyde with high concentrations found in the essential oils of Corymbia citriodora, M. officinalis, and various Cymbopogon species. It is used for perfuming soaps and other products (Bornscheuer et al., 2014 O Neil, 2006). Only one study described biotransformation of citronellal in rabbits. Ishida et al. could isolate three neutral metabolites of (+)-citronellal in the urine of rabbits (Figure 9.11). An additional acidic metabolite was formed as the result of regioselective oxidation of the aldehyde and dimethyl allyl groups (Ishida et al., 1989). Based on animal data, metabolism of citronellal is also expected in humans. [Pg.260]

Farnesol is present in many essential oils such as Cymbopogon species and neroli. It is used in perfumery and soaps to emphasize the odors of sweet oral perfumes and due to its xative and antibacterial properties (Bornscheuer et ah, 2014 O Neil, 2006). Interestingly, it is also produced in humans where it acts on numerous nuclear receptors Ooo and Jetten, 2010). In vitro studies using... [Pg.274]

New World from Cymbopogon ciiratus (DC) StapC Authentic oils obtained from each species were subjected to analysis and by GC/MS. A summary of the differences between their compositions can be seen in Table VII and VIII. Although the difierences between these oils appear to be major because of the high limonene content of the West Indian oils, it is easier and more prudent to use component ratios to differentiate between the oil as shown in Table IX. It is believed that examination of the hydrocarbons and oxygenated compounds separately is a good way to examine the authenticity of an oil. [Pg.207]

CHronella oil. C. is obtained from two tropical grass species of the genus Cymbopogon (Poaceae). [Pg.138]

Enantioselective GC has found a wide variety of applications, for instance, studies of citronellol (Ravid et al., 1992) and a-terpineol (Ravid et al., 1995) in a variety of species and verbenone in rosemary oils (Ravid et al., 1997). Chiral phases were applied to the separation of linalool and linalyl acetate in a variety of plant species (Konig et al., 1992 Cassabianca et al., 1998), extracts of Angelica seeds and roots (Holm et al., 1997) and other monoterpenoids in geranium oils (Kreis Mosandl, 1993). Separation of monoterpenes in Scots pine and juniper oils (Hiltunen Laakso, 1995), Abies (Holm et al., 1994) and Picea (Persson et al., 1996) oils and limonene, linalool, citronellal and P-citronellol Cymbopogon winterianus)... [Pg.56]

Linalool (3) is a monoterpene commonly found as a major volatile component of EOs in several aromatic plant species, such as Lavandula angustifolia Mill (Lamiaceae), Rosa damascena Mill. (Rosaceae), Citrus bergamia Risso (Rutaceae), Melissa officinalis L. (Lamiaceae), Rosmarinus officinalis L. (Lamiaceae), Cymbopogon citratus DC ex Nees (Poaceae), and Mentha piperita L. (Lamiaceae). Interestingly, many linalool-producing species are traditionally used as sedative, analgesic, hypnotic, or anxiolytic remedies in traditional medicine and some as well in aromatherapy (Elisabetsky et al., 1995a). [Pg.301]

Citronellal, a further aldehyde, is a main constituent in citronella oils (Cymbopogon nardus) and can also be found in Melissa officinalis and in various Eucalyptus species as E. citriodora. It is mainly used in perfumery [27]. [Pg.2979]

Besides the variability of the phytochemical composition of EOs mentioned above, the point is that insects vary enormously in their responses to secondary plant products. It is well known that the sensitivity of different insect species could be quite different for the same substance [11]. Oils from Cymbopogon nardus which killed quickly the bruchid A. obtectus [12] only knocked down and disabled the Angoumois grain moth Sitotroga cereallela [49]. [Pg.4095]
