✦ Synopsis

The composition of carrot seed oil has been studied using gas-liquid chromatography separation of components and characterisation by infra-red absorption and mass spectrometry. Evidence was found for the identities of 23 components. Of these, camphene, a-terpinene, terpinena4o1, a-terpineol, bornyl acetate, y-decanolactone, p-selinene, a-gurjunene and coumarin had not been previously reported as constituents of carrot seed oil.

-4 F root. Sabinene and myrcene were the only components which had a carrot root-like odour. On examination of carrots, these two hydrocarbons were found in unusually high concentration in the stems of the carrot tops. Although there are indications that the composition varies in different parts of the carrot root, the average concentration of these two components in the whole root was not very high.
