Cymbopogon Nardus
''Cymbopogon nardus'', common name citronella grass, is a species of perennial aromatic plant from the family Poaceae, originating in tropical Asia. ''C. nardus'' cannot be eaten because of its unpalatable nature and is an invasive species that renders pastureland useless, since cattle will starve even in its abundance. It is the source of an essential oil known as citronella oil, which is widely used for its natural insect-repelling properties. Essential oils are extracted from the aerial parts and applied topically or slowly burned (e.g. in a "citronella candle") as an insect repellent, particularly to deter haematophagous insects such as mosquitoes.

Citronella Oil
Citronella oilCitronella oil is an essential oil obtained from the leaves and stems of different species of '' Cymbopogon'' (lemongrass). The oil is used extensively as a source of perfumery chemicals such as citronellal, citronellol, and geraniol. These chemicals find extensive use in soap, candles and incense, perfumery, cosmetic, and flavouring industries throughout the world. Citronella oil is also a plant-based insect repellent and has been registered for this use in the United States since 1948. The United States Environmental Protection Agency considers oil of citronella as a biopesticide with a non-toxic mode of action. Citronella oil has strong antifungal properties. Types Citronella oil is classified in trade into two chemotypes:Chang, Yu Shyun, 2007, ''8 Map species from Malaysia for ICS,'' Forest Research Institute Malaysia, Workshop on NFP, 28–29 May 2007, Nanchang, PR China Ceylon type * CAS: 89998-15-2 * CAS: 8000-29-1 * EINECS: 289-753-6 * FEMA: 2308 * C ...

Citronella (genus)
''Citronella'' is a genus of trees and shrubs in the family Cardiopteridaceae described as a genus in 1832. It is native to tropical regions of South and Central America, insular Southeast Asia, Australia, and islands of the western Pacific. The genus was formerly treated as belonging to the family Icacinaceae. Few species have been cultivated. '' Citronella mucronata'', from Chile Chile, officially the Republic of Chile, is a country in western South America. It is the southernmost country in the world and the closest to Antarctica, stretching along a narrow strip of land between the Andes, Andes Mountains and the Paci ..., is remarkable for its hardiness compared to other members of this genus. It is one of the most well-known of the species and has been introduced to Europe.Mabberley, D. 1997. The Plant-Book. Cambridge University Press, Cambridge, United Kingdom. 858p.

Citronellal
Citronellal or rhodinal ( C10 H18 O) is a monoterpenoid aldehyde, the main component in the mixture of terpenoid chemical compounds that give citronella oil its distinctive lemon scent. Citronellal is a main isolate in distilled oils from the plants ''Cymbopogon'' (excepting C. citratus, culinary lemongrass), lemon-scented gum, and lemon-scented teatree. The (''S'')-(−)-enantiomer of citronellal makes up to 80% of the oil from kaffir lime leaves and is the compound responsible for its characteristic aroma. Citronellal has insect repellent properties, and research shows high repellent effectiveness against mosquitoes. Another research shows that citronellal has strong antifungal qualities.

Citronellol
Citronellol, or dihydrogeraniol, is a natural acyclic monoterpenoid. Both enantiomers occur in nature. (+)-Citronellol, which is found in citronella oils, including '' Cymbopogon nardus'' (50%), is the more common isomer. (−)-Citronellol is widespread, but particularly abundant in the oils of rose (18–55%) and ''Pelargonium'' geraniums. Preparation Several million kilograms of citronellol are produced annually. It is mainly obtained by partial hydrogenation of geraniol or nerol over copper chromite catalyst. Hydrogenation of both C=C bonds using a nickel catalyst gives tetrahydrogeraniol, yet another commercial fragrance. Homogeneous catalysts have been investigated for the production of enantiomers. Uses Citronellol is used in perfumes and as a fragrance in cleaning products. In many applications, one of the enantiomers is preferred. It is a component of citronella oil, an insect repellant. Citronellol is used as a raw material for the production of rose oxide. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Citronelle, Alabama
Citronelle is a city on the northern border of Mobile County, Alabama, United States. At the 2020 census, the population was 3,946. It is included in the Mobile metropolitan statistical area and is about north of Mobile. History The area was inhabited by indigenous peoples for thousands of years. By the time of European contact, the historic Choctaw and Creek people hunted in the area. The first known European explorers of this area were French in the 18th century. They learned that the land had healing herbs and mineral springs. The area was settled in 1811 and established as a jurisdiction (incorporated) in 1892. The name "Citronelle" is French and is derived from the citronella plant. In the late 19th century, the town became a popular resort destination because of the climate, herbs, and healing waters. Many hotels were built to accommodate the surge of visitors. On May 4, 1865, one of the last significant Confederate armies was surrendered by Lieutenant General R ...

Lasius
''Lasius'' is a genus of formicine ants. The type species for this genus is the black garden ant, '' Lasius niger''. Other major members, which live in drier heathland, are the cornfield ant, '' L. neoniger'', and '' L. alienus''. Other species include the temporary social parasites of the ''L. mixtus'' group and the hyper-social parasite '' Lasius fuliginosus''. '' Lasius flavus'' is also a commonly seen species, building grassy hillocks in undisturbed pasture. In the Alps, these mounds – always aligned east to catch the first rays of the rising sun – have been traditionally used by goatherds as natural compasses. Species in the subgenus ''Acanthomyops'', in particular '' L. interjectus'' and '' L. claviger'', are commonly known as citronella ants due to their citronella-like smell. Social parasitism Several species in this genus are noted to be social parasites. Some species such as ''Lasius latipes'' and '' Lasius murphyi'' are noted to have their mating flights in mi ...
