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.

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.

The Characteristics of Lavender Oils from Eastern Europe

Lavender oil (ex. Lavandula angustifolia Mill.) is produced commercially by a number of countries: France (the main supplier), Bulgaria, Moldova, Ukraine and Australia. The oils from each of these regions possess distinctive aroma characters, which range from the fine, flowery, fresh notes in the French oils to herbal, woody and camphoraceous with fatty notes in the Australian oils. Herein, it will be shown that these differences in aroma can be translated into a visual form (map) that assists comparisons with chemical analysis data.

Parameter test distillations for the superficial essential oils

Every effort was made to ensure that the herb used in the three 1975 distillations was a similar as possible. The same applied to the 1976 season's tests. Nonetheless, the smaller charges consistently return smaller yields of oil per kilo. This is due to an orderly phenomenon that could be discussed on another occasion.
