Croton cascarilla

Cascarilla Oil occurs as a light yellow to brown amber liquid with a pleasant, spicy odor. It is the volatile oil obtained by steam distillation of the dried bark of Croton cascarilla Benn. and of Croton eluteria Benn. (Fam. Euphorbiaceae). It is soluble in most fixed oils and in mineral oil, but it is practically insoluble in glycerin and in propylene glycol.

The bark of Croton eluteria (Euphorbiaceae) yields, on steam distillation, cascarilla essential oil which is used as a tonic. The main component of the acid fraction of this oil is cascarillic acid ([aJo -10.5°, methyl ester), a cyclopropane carboxylic acid (123) (79). The stereochemistry of the cyclopropane ring was established as trans by comparing H-NMR spectra and retention times on gas chromatograms of methyl esters of the synthetic trans- and cw-isomers with those of the natural compound (147). It is interesting that compounds with closely related structures have been found in an algae and in an insect. Dictyopterene A (124) was isolated from the essential oil of algae of the genus Dictyopteris (77) and (Z)-3-decenoic acid from carpet beetle, Anthrenus flavipes, as a sex pheromone (41).
