Oil Wintergreen

Wintergreen Oil. Water distillation of the leaves of Gaultheriaprocumbens L. yields an oil which consists of essentially one chemical constituent, methyl saUcylate. Because of this, the oil has been almost totally replaced by the synthetic chemical. Natural oil of wintergreen [68917-75-9] is a pale yellow to pinkish colored mobile Hquid of intensely sweet-aromatic odor and flavor. The oil or its synthetic replacement find extensive use in pharmaceutical preparations, candy, toothpaste, industrial products, and in rootbeer flavor. In perfumery, it is used in fougnre or forest-type fragrances. 

Esters, or salts of alkyl radicles, such as linalyl acetate, etc., are frequently the most important constituents of essential oils. Their importance is especially noteworthy in such cases as lavender , bergamot, peppermint, and wintergreen oils, and their estimation is very frequently necessary. The principle upon which this depends is the fact that most esters are decomposed by solution of caustic alkali (preferably in alcohol) according to the equation—...

Wintergreen Oil occurs as a colorless to yellow liquid with the characteristic odor and taste of wintergreen. It is obtained by maceration and subsequent distillation with steam from the leaves of Gualtheria procumbens L. (Fam. Ericaceae) or from the bark of Betula lenta L. (Fam. Betulaceae). It boils, with decomposition, between 219° and 224°. It is soluble in alcohol and in glacial acetic acid, and it is very slightly soluble in water.

Aromatic Compounds—The carbo-cyclic compounds which in number far exceed those of the aliphatic series were originally called aromatic compounds because many of them possess aromatic properties, e.g.j oil of wintergreen, oil of bitter almonds, etc. They were included with the paraffin compounds in the various groups of alcohols, aldehydes, acids, etc. Later it was found that they differed from the aliphatic compounds and finally it was shown that the hydrocarbon benzene is related to the aromatic compounds just as methane is to the aliphatic compounds, i.e,j as the mother substance.
