Determination of Methylmercury After Supercritical Fluid Extraction

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...

Hypericum carinatum: supercritical fluid extraction, HPLC determination and mathematical modeling

The genus Hypericum has been studied worldwide due to its pharmacological and biological effects. Uliginosin B, a dimeric phloroglucinol, and the benzophenones cariphenone A and B, for example, are the major responsible for the anti-proliferative and antimicrobial activities of Hypericum carinatum, a native species to southern Brazil. Although presenting therapeutic potential, these compounds a...

HPLC Method for the Simultaneous Determination of Ten Annonaceous Acetogenins after Supercritical Fluid CO2 Extraction

Annonaceous acetogenins (ACGs) isolated from Annonaceae plants exhibited a broad range of biological bioactivities such as cytotoxic, antitumoral, antiparasitic, pesticidal and immunosuppresive activities. However, their structures were liable to change at more than 60°C and their extraction yields were low using traditional organic solvent extraction. In the present study, all samples from Ann...
