Heterocyclic Trace Components in the Essential Oil of Coriander

The essential oil of coriander is obtained from the dried fruits of the plant Coriandrum sativum L, belonging to the family Apiaceae. It is marked by a very high percentage of linalool (approximately 70%), but the olfactory note of this monoterpene tertiary alcohol—when isolated by distillation—is quite different from the one of the purely synthetic counterpart. The special sensory effects of coriander oil have therefore always stirred the attention of flavorists and perfumers all over the world.

9th International Congress of Essential Oils—Report

The magnificent panorama of Singapore greeted delegates to the 9th International Congress of Essential Oils, March 13-17, 1983. As the only city in Southeast Asia with facilities for such a major International Congress, Singapore lived up to its reputation as the commercial and convention capital. The Mandarin Hotel also proved an excellent choice with more than adequate room for all the meetings, formal and informal, that are such an important part of every congress.

Citrus Oils in Perfumery and Cosmetic Products

New products always require new ideas. I feel very certain that the continued use of citrus products both synthetic and natural (I hope), will be assured for many centuries to come.

New compounds with small rings in essential oils

Despite the continuing discovery of new synthetic fragrance raw materials, essential oils still remain the other half of the foundation of perfumery. Consequently, the analysis of essential oils is still very much of interest, as is illustrated by the excellent series of articles by Lawrence in this journal. We now wish to report a number of products containing small (three-, four-, and five-membered) rings, most of which are found for the first time in essential oils. These products were isolated by chemical group separation, liquid and gas chromatography, whereupon the structures were determined by mass, infrared and NMR spectroscopy. All structures were confirmed by synthesis. The essential oils used were obtained from regular commercial sources.

The results obtained show a fingerprint gas chromatogram and a corresponding table of the composition for each oil.

Composition of Vietnamese Essential Oil from Melaleuca Leucadendron L.

In this paper, the chemical composition of the oil, established by a combination of gas-chromatography (GC) and gas-chromatography/massspectrometry (GC/MS), is described.

Continuous Steam Distillation of Essential Oils

A continuous process for steam distillation of essential oils was described in a previous article. Due to the continued widespread interest in this subject, we’ll provide further insight into the details of the process, as well as equipment specifications and cost estimates for distillation plants of various sizes.
