Isolation of Sulfonamides from Whole Egg by Supercritical Fluid Extraction

Isolation of chloramphenicol from whole eggs by supercritical fluid extraction with in-line collection.

Egg consumption, at more than 65 billion per year in the United States, represents a potentially significant source of exposure to drug residues, particularly if the laying hens are treated with antimicrobial compounds or fed a diet containing medicated feed. Residues resulting from the use of chloramphenicol (CAP) is especially problematic if this compound is not used in accordance with nation...

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...

Isolation of essential oil from different plants and herbs by supercritical fluid extraction.

Supercritical fluid extraction (SFE) is an innovative, clean and environmental friendly technology with particular interest for the extraction of essential oil from plants and herbs. Supercritical CO(2) is selective, there is no associated waste treatment of a toxic solvent, and extraction times are moderate. Further, supercritical extracts were often recognized of superior quality when compare...
