CA microparticles, nanofibrous networks, and cellular membrane with nonsteroidal anti-inflammatory drug ibuprofen produced by supercritical fluid
technology were reported for tissue engineering applications .
Carbon dioxide is commonly used as a supercritical fluid
because of its nontoxicity, nonflammability, low cost, moderate critical pressure, high critical density, and low critical temperature.
However, the supercritical fluid
extraction employing methanol as cosolvent used less solvent.
Juniper Pharma Services will bring its expertise in characterization, formulation development and GMP production to the supercritical fluid
Key words: physiochemical, solvent extraction, steam distillation, supercritical fluid
Scientists had generally thought the physical properties of supercritical fluids
changed gradually with pressure and temperature.
Extractions were performed using Supercritical Fluid
Extraction system (Thar Instruments, Inc., USA) which consists of a countercurrent column to extract the sample and a collection vessel to collect the extracted sample, as shown in Figure 4.

Rapid Expansion of Supercritical Solutions (RESS): The RESS process explores variations in solvency of the fluid with the pressure changes and consists in expanding the solution (solute dissolved in supercritical fluid
) to ambient conditions of temperature and pressure leading to decrease in solvent power and consequent solute precipitation due to supersaturation of the solution caused by a significantly decrease in solvent density Jung and Perrut (2001).
technology has been widely used for various applications such as extraction, reaction, chromatography and material processing [7, 8].
These claims are not limited to any specific extraction method and thus encompass both solvent and supercritical fluid
