In this paper we aimed to establish the content in polyphenolic compounds (flavones and polyphenolcarboxylic acids) in the soft extract of Elaeagnus angustifolia L. (oleaster) young branches, using high-performance liquid chromatography coupled with mass spectrometry (HPLC-MS). The comparative analysis of the chromatograms obtained before and after hydrolysis showed a complex composition. We id...

Micropropagation of three Echinacea species, E. angustifolia DC., E. pallida Nutt., and E. purpurea Moench., was investigated as a potential means of germplasm preservation of species faced with overcollection in the wild and rapid clonal propagation of elite individuals with unique medicinal or ornamental properties. Very high contamination rates occurred with shoot-tip explants but not with n...

This paper describes the design of a new instrumental technique, Gas Chromatography Recomposition-Olfactometry (GC-R), that adapts the reconstitution technique used in flavor chemistry studies by extracting volatiles from a sample by headspace solid-phase microextraction (SPME), separating the extract on a capillary GC column, and recombining individual compounds selectively as they elute off o...

Using enzyme polymorphism at IO loci , genetic variation was analysed in both wi ld and cuiti vated olive growing around the Mediterranean Basin. Twenty five and 21 alle1es were observed in the 333 wild olive trees analysed and in the culti ved materia1 (418 trees) respectively. Twenty one of these alleles were common to the two forms. In addition, in most the situations of sympatry between wil...
