Effects of Operating Parameters on the Supercritical Fluid Extraction of Pharmaceutical Plants

In this paper operating parameters that used by various researchers for supercritical fluid extraction of pharmaceutical agents from six various types of pharmaceutical plants were studied. Materials that studied here have many applications in the pharmaceutical, food and cosmetic industries and nowadays we see an increasing demand for replacing of these materials by synthetic materials. In this work, effects of various parameters such as temperatures and pressures of extraction fluid, extraction time, mean particle size of powders and other effective parameters on the yield of extraction and composition of extract were reviewed. And optimum conditions for the best composition of extract and highest yield of extraction were reported.
