The insecticidal activity of Satureja hortensis L. extracts obtained by supercritical fluid extraction and traditional extraction techniques

Laurel Extracts Obtained by Steam Distillation, Supercritical Fluid and Solvent Extraction

The chemical composition of laurel leaves and fruits essential oils (content of 0.917 and 0.747%, respectively) and laurel leaves extracts obtained at different pressures/temperatures by supercritical fluid extraction (SFE) were studied by GC-MS. The predominant compound in the essential oils and in CO2 extracts obtained at pressures/temperatures of 100 bar/40°C and 250 bar/40°C was 1,8-cineole...

Anti-Trichomonas vaginalis activity of Hypericum polyanthemum extract obtained by supercritical fluid extraction and isolated compounds.

The anti-Trichomonas vaginalis activity of Hypericum polyanthemum extract obtained by supercritical fluid extraction (50°C, 150bar) and the chemical compounds isolated and purified from this extract (benzopyrans HP1, HP2, HP3, and phloroglucinol derivative uliginosin B) were assessed. All samples had anti-T. vaginalis activity; however, HP1 demonstrated the best selectivity against this protozo...

Trypanocidal Activity of Oil of the Young Leaves of Nepeta cataria L. Obtained by Solvent Extraction

Trypanocidal activity was found in the volatile oil of the Young leaves of Nepeta cataria L. which has been extracted by diethyl ether and analyzed by GC and GC/MS. Four compounds in the oil of N. cataria, representing 97.53% of the oil were identified. The oil was enriched of monoterpenes with α- citral (51.95%) as the major compound. Other main compounds were β- citronellol (9.03%), geraniol ...

Supercritical Fluid Extraction+supercritical Fluid Chromatography

high pressures also requires special equipment. In summary, both RESS crystallization and SAS crystallization appear to be promising methods for generating supersaturation and therefore represent alternatives to conventional crystallization. Such alternatives may prove attractive in applications such as polymer and pharmaceutical processing, or in particle design for drug delivery. It is possib...
