Chemische Eigenschaften
Herbaceous plant native to eastern and central Europe; it prefers shady growing sites. It grows 30 to 80 cm (12 to 31 in.) tall, with roots clustered in bundles, a branched stalk, alternate leaves and yellow flowers. Leaves are fragrant and anise-flavored. The plant flowers from July to August. The parts used are the flowering tops and leaves. Tarragon has a sweet, spicy odor and a sweet, anisic, fresh, green flavor reminiscent of basil and anise. This herb is commonly used to flavor vinegar and to season meats, soups, vegetable and fish dishes.
Chemische Eigenschaften
Estragole has an odor reminiscent of anise with a corresponding sweet taste (differing from anethole)
Chemische Eigenschaften
Basil oil, methyl chavicol (estragole)-type (Réunion type, exotic type) is obtained by steam distillation of the flowering tops or whole plants of Ocimum basilicum L. (Lamiaceae), which was formerly grown in Réunion and Madagascar. Today, the oil is produced in India and Vietnam on relatively large scale (～100 and 30 t/yr, respectively) and also in Egypt, but in small quantities. It is a light yellow liquid with a fresh, green, spicy odor characteristic of methyl chavicol (estragole).
d²⁰₂₀ 0.948–0.970; n²⁰_D 1.5100–1.5200; α²⁰_D ?1°to +2°; solubility: 1 vol in ≤7 vol 80% ethanol; content by GC: methyl chavicol 75–87%; linalool 0.5–3%(data for the classical “exotic” type; Indian types may contain up to ～20% linalool).
Chemische Eigenschaften
colourless liquid with an aniseed smell
Occurrence
Reported found in anise oil.
Verwenden
4-Allylanisole has been used as a reference standard for the analysis of 4-allylanisole in essential oils by high performance liquid chromatography (HPLC) equipped with fluorometric detector and in emissions from live vegetation by solid-phase microextraction (SPME) combined with proton transfer reaction mass spectrometry (PTR-MS). It may be used as a reference standard for the determination of 4-allylanisole in food products by simultaneous distillation-extraction (SDE) followed by analyses using capillary gas chromatography (GC)-flame ionization detector (FID) and GC-MS.
Verwenden
insect atttractant, skin irritant, carcinogen
Verwenden
In perfumes and as flavor in foods and liqueurs.
Definition
ChEBI: Estragole is an olefinic compound.
synthetische
Obtained by fractional distillation of the oil of turpentine or by treating a solution of the same oil in ether with an aqueous solution of mercuric acetate and subsequently heating the aqueous phase with zinc and sodium hydroxide; forms allyl bromide and magnesium p-methoxy phenate in ether.
Composition
The herb is reported to contain polyacetylenic compounds (capillene; phenyl-1,3-pentadiyne; acetylenic alcohol and its glucoside; capillone and dehydrofalcarinone); coumarinic and isocoumarinic derivatives (artemidinol, artemidiol, scopoletine, herciarine); alcohols (9-hydroxygeraniol; 4-methoxybenzyl alcohol); aldehyde (CoE, 2000).
Taste threshold values
Taste characteristics at 10 ppm: sweet, licorice, phenolic, weedy, spice, celery-like
