Phytochemical composition and the cholinesterase and xanthine oxidase inhibitory properties of seed extracts from the palm fruit.

The chemical composition and biological properties of palm (Lindl.) H. Wendl.

Chemical characterisation and biological activity of leaf essential oils obtained from Pistacia terebinthus growing wild in Tunisia and Sardinia Island.

In the present work the chemical compositions, measured by GC and GC-MS, of the essential oils obtained by hydrodistillation from leaves of Pistacia terebinthus collected in Bizerte (Tunisia) and Baunei (Italy) are reported. Both essential oils possessed high content of monoterpene hydrocarbons (86.3% and 90.

Chemical polymorphism of essential oils from populations of Laurus nobilis grown on Tunisia, Algeria and France.

The compositions of the essential oils isolated from the aerial parts of tree Mediterranean populations of Laurus nobilis L. collected during the flowering phase on Tunisia, Algeria and France, were studied by GC and GC-MS. The analysis has allowed identifying 54 components.

Essential oils of Daucus carota subsp. carota of Tunisia obtained by supercritical carbon dioxide extraction.

The essential oils and supercritical CO2 extracts of wild Daucus carota L. subsp. carota from two different sites in Tunisia were investigated.

Biological activity evaluation of the oils from Laurus nobilis of Tunisia and Algeria extracted by supercritical carbon dioxide.

Isolation of essential oil from dried and ground leaves of Laurus nobilis L. from Algeria and Tunisia were obtained with two different methods: by means of classical hydrodistillation (HD) and by using carbon dioxide in the supercritical state (SFE). The effect of extraction pressure on the yield and composition of the L.

Extraction and separation of volatile and fixed oils from berries of Laurus nobilis L. by Supercritical CO2.

Isolation of volatile and fixed oils from dried berries of Laurus nobilis L. from Tunisia have been obtained by supercritical fractioned extraction with carbon dioxide. Extraction experiments were carried out at a temperature of 40 degrees C and pressures of 90 and 250 bar.
