Coriander oil

ANETHOLE Up to 90+% in anise seed oil, 70+% in fennel and star anise oils, and in varying amounts in betel leaf, dill seed, carrot seed and coriander oils.

Isolation from Essential Oils. Linalool can be isolated by fractional distillation of essential oils, for example, rosewood oil, Shiu oil, and coriander oil, of which Brazilian rosewood oil is probably the most important. 

Coriander oil is obtained by steam distillation of ripe fruits of Coriandmm sativum L. (Apiaceae). It is an almost colorless to pale yellow liquid with a characteristic odor, reminiscent of linalool. 

The main component of coriander oil is (+)-linalool (60-80%) [452-460c]. Mono- and polyunsaturated fatty aldehydes, although minor components, contribute to the characteristic aroma of the oil because of their powerful odor. In contrast to the seed oil, coriander leaf oil contains these aldehydes as main constituents, e.g. 2-decenal and 2-dodecenal. 

Coriander is mainly cultivated in Eastern Europe. World-wide oil production is 50-100 t/yr. Coriander oil is no longer important as a raw material for the production of linalool and its derivatives. However, it is still used extensively in seasoning mixtures and in perfume compositions. FCT 1973 (11) 1077 [8008-52-4], [84775-50-8],... 

Yeast, fungi, insects widespread among higher plants. (-)-linalool >80% in Shiu oils (Cinnamomum camphora) (+)-linalool 60-70% in coriander oil. 

Linalool (3,7-dimethyl-l,6-octadien-3-ol) (62) occurs as one of its enantiomers in many essential oils, where it is often the main component. (/ )-(-)-Linalool for example occurs at a concentration of 80-85% in Ho oils from Cinnamomum camphora rosewood oil contains ca 80%. (S)-(+)-Linalool makes up 60-70% of coriander oil [26]. 

The saponifiable portion of the fatty oil accounts for about 90% of the total fixed oil and is characterized by a very high content of octadecenoic acids. Petroselinic and oleic acid occur at similar levels and jointly comprise 74-85%, linoleic 7-16% and palmitic 4-8%, of the constituent fatty acids. During prolonged storage of the spice, the free fatty acid content gradually increases and this is a good indicator of the age of the material. The contents of fatty acids, sterols and total tocopherols in a deodorized oil derived from coriander seeds (yield up to 28%) are compared with those in sunflower oil and tests on the biological effects of coriander oil are reported by Mironova et al. (1991). Of the fatty acids present, total C18 1 acids (petroselinic acid + oleinic acids) constituted 80—82% and petroselinic acid alone 50—60%, and the food value was lower than that of sunflower oif. Kim et al. (1996) found the production of petroselinic acid from cell suspension cultures of C. Sativum. 

Hydrodistillation of coriander seeds yields about 0.35% (w/w) oil based on dry weight (Msaada et al., 2007). Extraction of ripe fruits of C. sativum by steam distillation and by supercritical fluid extraction (SEE), using C02, was compared. The percentage composition of the 40 identified compounds was compared with the composition of commercial coriander oil extracted by hydrodistillation. The oil obtained by SFE showed some quantitative and qualitative differences, giving a superior aroma compared with that of the oil obtained by hydrodistillation (Anitescu et al., 1997). 

Polshkov (2001) studied the effect of storage time and condition on the composition of coriander oil after 1, 2, 4, 6, 9 and 12 months by GC-MS analysis. In the fresh specimen, the monoterpene hydrocarbons, y-terpinene and a-pinene, were detected in considerable amounts and camphor, linalyl acetate and geranyl acetate in smaller amounts. Aldehydes (neral, 2-decenal and undecenal) were also found. During 1 year of storage in the dark, the composition of the oil changed...

Pascual Villalobos (2003) found the potential of plant essential oils against stored-product beetle pests. Coriander oil (10 pi) showed activity against the bruchid Callosobruchus maculates, the cereal storage pest. 

The inhibitory effects of the essential oils of coriander on the mycelial growth and ochra-toxinA production by A. ochraceus NRRL 3174 were studied by Basilico and Basilico (1999). Sage and coriander showed no important effect at any of the concentrations studied. Meena and Sethi (1994) also studied the potential of coriander oil in the control of A. niger, Saccharomyces cerevisiae, Mycoderma sp., L. acidophilus and Bacillus cereus.

Coriander Oil occurs as a colorless or pale yellow liquid with the characteristic odor and taste of coriander. It is the volatile oil obtained by steam distillation from the dried ripe fruit of Coriandrum sativum L. (Fam. Umbelliferae).
