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. 

Other synthetics with cost advantages and large volume productions are L-carvone [6485-40-17, the primary component in natural spearmint essence D-carvone [2244-16-8], the primary component in natural diU and caraway anethol [4180-23-8], in place of anise and fennel spices and smaller amounts of thymol [89-83-8] replacing thyme and disulfide synthetics for onion and gadic. AH of these synthetics must be labeled as artificial which may limit their use among consumers.

Anisic aldehyde, CgHgOj, is a methyl ether of para-oxy-benzaldehyde, which is found to a small extent in the oils of fennel and aniseed. It is manufactured on an extensive scale artificially, and is the basis of all the perfumes of the hawthorn or May blossom type. It is known commercially as aubepine . A certain amount of anisic aldehyde is obtained as a by-product in the manufacture of coumarin, but the greater- part of it is obtained by very careful oxidation of anethol, the characteristic constituent of aniseed oil, which has the constitution—... 

Anethol is the raw material from which most of the artificial hawthorn perfume is manufactured. This perfume consists of anisic aldehyde, known commercially under the name aubepine .

Anethole, C H O, a major constituent of the oil of anise, has the lH NMR spectrum shown. On oxidation with Na2Cr207, anethole yields p-methoxy-benzoic acid. What is the structure of anethole Assign all peaks in the NMR spectrum, and account for the observed splitting patterns. 

Later in intra-uterine life, the human infant is susceptible to early chemical prompting, but again the affector route is not known with certainty. Neonatal discrimination in favour of familiar (maternal) amniotic fluid is demonstrable, suggesting that the foetus already has active chemosensory capacities (Schaal, 1998). Smell and taste are operative in the near full-term foetus since it shows detection of about 120 mg/day maternal intake of anethole (as anise condiments) within a few days before parturition this exposure induced subsequent preferential responses by babies to anethole (Schaal et ai, 2000). The human neonate is not likely to have its organ as a fully functioning chemosensor,...

C10H12O, Mr 148.20, tranx isomer pioi.vkPa 234°C, pi.6kPa H5°C, df 0.9883, 1.5615, occurs both as its cis and trans isomers in nature however, /ran -anethole is always the main isomer. Anethole occurs in anise oil (80-90%), star anise oil (>90%), and fennel oil (80%). 

Anethole can be crystallized from oils in which it occurs as a major component (star anise and sweet fennel oils), and estragole containing oils (e.g., basilicum oil). 

Anise oil. Aniseed oil is obtained by steam distillation of the fruits of Pimpinella anisum L. (Apiaceae). It is a colorless to pale yellow liquid or crystalline mass with a powerful, sweet odor, characteristic of anethole. 

The main component of anise oil is trans-anethole, which is present at a concentration of 87-94% and which determines the melting point of the oil [263 266b]. 

The oil was formerly produced in many countries, mainly in eastern Europe, but has now been replaced, to a large extent, by the less expensive star anise and fennel oils which also contain a high percentage of anethole. 

Fennel oil is mainly used in flavoring oral care products and in pharmaceutical preparations. A reasonably quantity of fennel oil is used for the production of pure anethole for flavouring alcoholic beverages (anise liqueurs) [513dj. FCT 1976 (17) p.529 [8006-84-6], [84625-39-8]. 

The main component of star anise oil, as in anise oil, is /rans-anethole (86 93%) [779 782bj. Pure anethole can be obtained by rectiflcation (see p. 127). Star anise oil has replaced true anise oil derived from Pimpinella anisum in the production of natural anethole. 

Star anise oil and its product, anethole, are used primarily in the alcoholic beverage industry (anise liquors), but also for flavoring food and oral care products. FCT 1975 (13) p.715 [68952-43-2], [84650-59-9]. 

Another example is the synthesis of anisaidehyde from anethole obtained from star anise oil from the fruit and leaves of lllicium verum. Anethole can be oxidised, for instance, by chromic acid (a mixture of sodium dichromate and sulfuric acid) to anisaidehyde (Scheme 13.7). Star anise oil is produced in China in annual quantities of 500-800 t [3].

Licorice is one of the most widely investigated plant products. Modern chemistry has allowed for the isolation, separation, and characterization of dozens of different compounds found in the root extract. No single component accounts for licorice s distinctive flavor, but anethole comes close. This compound occurs in the anise plant, from which it can be extracted, or it can be synthesized in the laboratory. Candy makers commonly use anethole to impart a licorice flavor to their products, like that black stringy confection. This is why naming the treat licorice is misleading. Even when it is made with real licorice extract, the concentration of licorice compounds is very low. We should be aware of this, because it means that neither the problems nor the potential therapeutic effects that we attribute to real licorice apply to the twists we chew on in movie theaters. Real licorice twists do exist, though — mostly in Europe.

The aromatic, warm, and sweetish odor and taste of the seed, leaves, and stem arises from the presence of a volatile oil that contains anethole p-propenyl phenylmethyl ether, C3H5C6H4OCH3), the derivatives of which (anisole and anisaldehyde) are used in food flavoring, particularly bakery, liqueur, and candy products, as well as ingredients for perfumes. For commercial production of anise oil, the seeds and the dried, ripe fruit of the plant are used. Anise oil. a colorless to pale-yellow, strongly refractive liquid of characteristic odor and taste, is prepared by steam distillation of the seed and fruit. The oil contains choline, which finds use in medicine as a carminative and expectorant.
