Micronization of Taxifolin by Supercritical Antisolvent Process and Evaluation of Radical Scavenging Activity
The aim of this study was to prepare micronized taxifolin powder using the supercritical antisolvent precipitation process to improve the dissolution rate of taxifolin. Ethanol was used as solvent and carbon dioxide was used as an antisolvent. The effects of process parameters, such as temperature (35-65 °C), pressure (10-25 MPa), solution flow rate (3-6 mL/min) and concentration of the liquid ...
متن کاملSupercritical Antisolvent Micronization of Minocycline Hydrochloride
Micronization of minocycline hydrochloride dissolved in ethanol and with supercritical carbon dioxide as antisolvent was successfully performed using a recently built SAS apparatus. Amorphous particles of minocycline ranging from 100 to 1000 nm (depending on the operating conditions) were obtained. The mean particle size and the particle size distribution were determined by Dynamic Light Scatte...
متن کاملPurification and Simultaneous Micronization of Polymers by Supercritical Antisolvent Precipitation
One of the most important environmental concerns for the polymer industry is to produce new products with near-zero residual monomer content. A new process based on supercritical CO2 has been successfully tested for the extraction of the residual monomer and the simultaneous micronization of the polymer. The process has been tested on a pilot-scale plant. The reduction of methyl methacrylate (M...
متن کاملEvaluation of the antioxidant activity of Thymus Using Electrochemical Methods and radical scavenging method
Thymus is regarded as one of the medicinal species, which according to obtained chromatograms of floral water of Thymus; one of the main components is thymol as strong antioxidant. In this study the appropriate and physically powerful correlation was found between the anti-radical and oxidation potentials. The antioxidant activity of the Thymus was measured by using square wave and cyclic volta...
متن کاملPolymer Encapsulation of Fine Particles by a Supercritical Antisolvent Process
Coating and encapsulation of fine particles with polymer using a supercritical antisolvent (SAS) coating process was investigated in this research. Synthesized submicron silica particles were used as host particles and poly(lactide-co-glycolide) (PLGA), a biodegradable polymer used for controlled release of drugs, was chosen as the coating material. In the SAS coating process a suspension of si...
