Betula lenta

Some oils consist almost entirely of esters for example, those of Oaultheria procumhens and Betula lenta contain about 99 per cent, of methyl salicylate. Bergamot and lavender owe the greater part of their perfume value to esters of linalol, of which the acetate predominates. Geranium oil owes its fragrance chiefly to geranyl esters, of which the tiglate is the chief. On the other hand, oils such as spike lavender, sandalwood, lemon-grass, and citronella contain but small quantities of esters, and owe their perfume value to entirely different types of compounds.

Salicinum, Salicin, C13H1807, is a glucoside obtained from several species of Salix, the willow, and populus, the poplar, trees of the nat. ord. Salicaceae. It is found also in Gaultheria procum-bens, the wintergreen, nat. ord. Ericaceae and in Betula lenta, the sweet birch, nat. ord. Betulaceae the volatile oils of which, distilled from the leaves of the former and from the bark of the latter, consist almost entirely of methyl salicylate. [Pg.529]

Oleum Betulae, Oil of Betula (Oil of Sweet Birch), is a volatile oil distilled from the bark of Betula lenta, the sweet birch. It is identical with methyl salicylate and nearly identical with Oil of Gaultheria. [Pg.530]

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. [Pg.504]

Wintergreen Oil.—There are two natural sources of this oil, the Gaultheria procunxhens and the Betula lenta. Both oils consist, almost entirely of methyl salicylate and are practically identical in properties, the chief difference being that the former has a slight leevo-rotation, while the latter is inactive. [Pg.107]

A sesquiterpene alcohol, betulol, OuH O, and its acetic ester have been found in the oil of Betula lenta. [Pg.282]
