Progress in Essential Oils: Sweet Fennel Oil and Extract
In this column, Brian M. Lawrence reviews the composition of sweet fennel oil and extract as found by various researchers. For example, a commercial sample of sweet fennel oil was screened for its anti-platelet activity by Tognolini et al. (2006) and Guerini et al. (2006) using GC-FID and GC/MS. Results are reported herein.

Essential Oil Essential Oil Research and Symposia 1969-1989
The time is ripe, perhaps, to review the development which has taken place since the Essential Oil Symposium started in 1969—and try to see a little ahead. The aims of the symposia should be as before: namely, to bring together scientists who are interested in all aspects of essential oil research, for discussions of common problems and presentation of their results, to the benefit of essential oil research in general.

Material Review: Clary Sage Oils
Variation in composition and enantiomeric analyses of commercial vs. new Kashmir clary sage oils. Commercial clary sage oils were analyzed along with a newly available Kashmir oil (Himalayan Foothills Oils, Srinagar, India). All of the oils were high in linalool (14.7–25.1%) and linalyl acetate (55.0–72.4%).

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.
