Supercritical Fluid Extraction of β-Carotene from Crude Palm Oil Using CO2 in a Bubbler Extractor: Mass Transfer Study

In this study, the diffusivity and volumetric mass transfer coefficients for the extraction of β-carotene from crude palm oil using CO2 solvent in supercritical fluid were determined in the pressure range of 7.5-17.5 MPa and temperature range of 80-120 ºC. For this purpose, a statistical method was applied in order to minimize the number of experiments required. The volumetric ma...

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...
