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.

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.

Comparative Investigations of the Essential Oil and Volatiles of Spearmint
The objective of this work is to identify the fragrance compounds of this oil and its SPME-headspace by means of gas chromatographic- spectroscopic (GC and GC/MS using different polar and chiral phases) and olfactoric methods (GC-sniffing technique and olfactory correlations) to find out the importance of each single constituent with their specific odor attributes, responsible for the characteristic and pleasant spearmint aroma for the first time.

Unsaturated Components in the Essential Oil of Anthemis nobilis L. (Roman Chamomile)
French authors recently presented their analytical findings on the oil using the negative chemical ionization technique in mass spectrometry. They tracked the GLC profile of the complete oil with the mass numbers of the quasi-molecular ions [M-H]- in combination with the carboxylate anion RCOO-. Thereby inter alia the presence of five esters derived from methacrylic or crotonic acid was reported, however, without giving definite structural assignments for the individual components. The same holds for eight esters of the angelate or tiglate type, respectively. We have worked in a more traditional way and wish here to present the results concerning some of these methacrylates, crotonates, angelates and tiglates. All esters mentioned by us have proved by comparison with authentic synthetically prepared samples.

Detection of new trace constituents in the essential oils of Cymbopogon flexuosus
The essential oil of lemongrass is derived chiefly from two important species of Cymbopogon, C. flexuosus, which has been the subject of numerous investigations, and C. citratus, C. flexuosus (Stend.) Wats (sym. Andropogon nardus var. flexuosus Hack), is native to India. Its two strains, SD-68 and OD-19, which have been cultivated at our Kukrail Research Farm, Lucknow, were examined by gas chromatography and the presence of new trace constituents was established for the first time.
