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.

Adesmia Boronioides, also called Paramela belongs to the family of Fabacea. It is a small bush that grows up between 0.4 and 2 meters high.

Inside Paramela Essential Oil: Perfumery Usage, Chromatographic Profile and Chemical Composition

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.

Gas Chromatographic Analysis on Turkish Rose Oil, Absolute and Concrete

The analysis of rose products maybe realized by gas or liquid chromatographic techniques. Our investigations showed that liquid chromatography have been used only in a few studies to separate essential oils and terpenoid compounds, and a sufficient separation has not been obtained.

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%).
