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.

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.

Beta-Cyclodextrin
Recent advances in enzyme technology, coupled with increased scale production, have brought β-cyclodextrin (BCD) to a point where it can be used economically in food and cosmetic applications, although it cannot be considered as a cheap carrier. Many workers, however, are finding applications for its unique properties and stabilizing ability. In such cases it is cost effective.
