Essential Oil Contents and Chemical Composition of Turkish Laurel Leaves

Laurus nobilis L., an evergreen tree, is cultivated in many temperate and warm parts of the world, particularly in the countries bordering the Mediterranean.

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.
