Tarragon oil

Tarragon oil contains roethi l-chavicol ( the " eairagol o[ Grimaui), ocimene( ), phellandreoe, and some unidentifiivd couatimenca which influence its odour and flavour. 

Like most phenols, it gives an intense blue colour with solution of ferric chloride. By heating it with alcoholic potash and methyl iodide it is converted into methyl-chavicol or estragol, the characteristic constituent of tarragon oil.

Tarragon oil (estragon oil) is produced by steam distillation of leaves, stems, and flowers of Artemisia dracunculus L. (Asteraceae). It is a pale yellow to amber liquid with a characteristic, spicy, delicate estragon odor reminiscent of liquorice and sweet basil. The following specifications refer to tarragon oil obtained from plants cultivated in southern France and in Piedmont (Italy). 

Estragole is the main constituent of tarragon oil (68—80%) and primarily determines the sensory properties [786-788]. 

Worldwide production of tarragon oil only amounts to a few tons per year. It is used mainly in aroma compositions, smaller quantities are employed in perfumery. FCT 1974 (12) p.706 [8016-88-4], [90131-45-6]. 

Tarragon Oil occurs as a pale yellow to amber liquid having a delicate, spicy odor similar to fennel and sweet basil but characteristic of Tarragon Oil. It is the volatile oil obtained by steam distillation from the leaves, stems, and flowers of the plant Artemesia dracunculus L. (Fam. Asteraceae). It is soluble in most fixed oils and in an equal volume of mineral oil, occasionally becoming hazy on further dilution. It is relatively insoluble in propylene glycol, and is insoluble in glycerin.

Tarragon Oil (Artemisia dracunculus) A strongly aromatic, licorice-flavored spice. Mmmm Mmmm Love it in a nice Bearnaise sauce. Lawrence explains a little more about it [2, vol. IV, p. 5]. 

Tarragon Oil (Artemisia dracunculus) You can see in Table XIII from the Elemicin Section that, aside of any other goodies, regular tarragon oil is mostly made of methylchavicol (73-82%). It was no mistake that the aberrant forms of tarragon ( Russian, German ) did not show any methylchavicol. Other studies show little-to-none as well [57]. 

Tarragon Oil Table XIII in the Elemicin Section shows again that methyleugenol is part of the goodies in the tarragon oils. 

Tarragon Oil Yup, those same tarragon oils fromTable XIII. In that study only German tarragon has any appreciable methylisoeugenol content with 1.89%. However, another study [69] showed that four different samples of Russian tarragon grown in the U.S. had contents of 2.79 - 2.292%.

Phytochemistry The flowering herb contains 0.1-0.7 % essential oils, 41.8 mg% (for absolute dry weight) carotene, 190 mg% vitamin C and alkaloid traces (Khalmatov et al. 1984). The essential oils of Central Asian plants contain 65-85 % d-sabinene, about 10 % myrcene, 5 % sesquiterpene fractions, about 0.5 % methoxy-cinnaroic aldehyde, and 7-15 % resins. Central Asian tarragon oil is substantially different from Western European tarragon oil because it doesn t contain methyl-chavicol (Khalmatov 1964). The herb contains flavonoids, alkamides, and coumarins (Mallabaev et al. 1971, 1970 Mallabaev and Sidyakin 1976 Hofer et al. 1986 Bohm and Stuessy 2001 Saadali et al. 2001 Logendra et al. 2006). 

PROBLEM 17.50 Estragole (1) is a major constituent of tarragon oil. Treatment of 1 with hydrogen bromide in the presence of peroxides affords 2. Compound 2 reacts with Mg in ether, followed by addition of carbon dioxide and acidification, to give 3. Spectral data for compound 3 are summarized below. Deduce the structure of compound 3 and propose structures for estragole and compound 2. 

Tarragon oil consists mainly of estragole (methyl chavicol, 70-81%). ° Other components present include capillene, ocimene, nerol, thujone, 1,8-cineole, 4-methoxycinna-maldehyde, a-pinene (0.89%), P-phellandrine (1.07%), limonene (2.68%), and y-terpinene (10.40%), among others nerol has been... 

Although undiluted tarragon oil has been reported to be irritating to rabbit skin and the backs of hairless mice, it was found to be nonirritating and nonsensitizing to humans at a concentration of 4% in petrolatum it was also not phototoxic. The ethanolic extract (tarralin) has recently been shown to be devoid of acute and chronic toxicity in rats at 1000 mg/kg/day oral dose. Mutagenic activity...
