The aim of this investigation was to develop a procedure to improve the dissolution and bioavailability of silymarin (SM) by using bile salt-containing liposomes that were prepared by supercritical fluid technology (ie, solution-enhanced dispersion by supercritical fluids [SEDS]). The process for the preparation of SM-loaded liposomes containing a bile salt (SM-Lip-SEDS) was optimized using a c...

This paper primarily concerns strictly supercritical fluid models, which arise as functional law of large numbers approximations for overloaded processor sharing queues. Analogous results for critical fluid models associated with heavily loaded processor sharing queues are contained in Gromoll et al. [9] and Puha and Williams [15]. An important distinction between critical and strictly supercri...

a pressurized fluid extraction (pfe) method for the extraction of pistachio oil was developed using a modified supercritical fluid extractor. the supercritical fluid extraction apparatus was modified to be able to pump liquid solvent and co2 into the extraction vessel alternatively. the experimental results showed that the extraction yield was independent of the extraction pressure. it was also...

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 mass transfer coe...

Supercritical fluid extract and ethanol extract of Vitex negundo Linn. were subjected to the chromatographic evaluation for identification of their constituents. Free radical scavenging activity of both extracts was studied by subjecting them to DPPH assay. IC(50) values of ethanol and supercritical fluid extract of Vitex negundo indicate that ethanol extract has stronger reducing potential and...
