Essential oils — Determination of 1,8-cineole content

The determination is carried out by measurement of the crystallization temperature of a mixture of essential oil and o-cresol. This temperature depends on the 1,8-cineole content of the essential oil. A table gives the 1,8-cineole content as a function of the crystallization temperature of the essential oil/o-cresol mixture.
