“…This might be the reason that crude extraction yield was changed significantly when temperature was changed over the range of 40−60°C. A moderate increase in temperature can lead to a large decrease in fluid density, with a consequent reduction in solute solubility (Roop et al 1989). However, the increase in temperature will also accelerate mass transfer and improve the extraction yield (Wang et al 2008).…”

The bioactive flavonoid compounds of spearmint (Mentha spicata L.) leaves were obtained by using supercritical carbon dioxide (SC-CO 2 ) extraction. Extraction was carried out according to face-centred central composite design, and independent variables were pressure (100, 200 and 300 bar), temperature (40, 50 and 60°C) and co-solvent amount (3, 6 and 9 g/min). The extraction process was optimized by using response surface methodology for the highest crude extraction yield of bioactive flavonoid compounds. The optimal conditions were identified as 209.39 bar pressure, 50.00°C temperature and 7.39 g/min co-solvent amount. The obtained extract under optimum SC-CO 2 condition was analysed by high-performance liquid chromatography. Seven bioactive flavonoids including catechin, epicatechin, rutin, luteolin, myricetin, apigenin and naringenin were identified as major compounds. The results of quantification showed that spearmint leaves are potential source of antioxidant compounds.

“…Near the system critical pressure, the fluid density is very sensitive to temperature. A moderate increase in temperature can lead to a large decrease in fluid density, with a consequent reduction in solute solubility [15]. However, the increase in temperature will also accelerate mass transfer and improve the extraction yield [16].…”

Phenolic compounds are components commonly found in fruits and vegetables. Recently, they have been subject of considerable scientific and therapeutic interest mainly due to their antioxidant properties and related healthpromoting benefits, as confirmed by the numerous papers devoted to various properties of these compounds. Thus, the extractions of phenolic compounds with functional properties from natural sources have attracted special interests. Supercritical fluid extraction offers a number of advantages over conventional extraction methods above all in relation to the conditions employed during the extraction process that ensures minimal alteration of the active phenolics and the healing properties could be more easily preserved. This work provides an updated overview on the principal applications of Supercritical fluid extraction in recovery of bioactive phenolics emphasizing the effects of temperature, pressure, addition of co-solvents and time on the extraction yield of these compounds and their antioxidant activities for a possible applications in food, cosmetic or pharmaceutical industries.

SummaryAlthough the last two decades has seen a keen interest in using supercritical fluids as media for material processing and chemical reactions owing to their unique physical properties, this technology has been underutilized in medical radioisotope processing and chemistry. The successful application of this technology necessitates not only having a sound knowledge of the physicochemical properties and phenomena occurring within such critical states of matter, but also a clear idea of the tools needed and means for applying them. These topics will be presented under the cover of two parts. Part I will address topics on the general background of supercritical fluid technology, equipment needed, whether for chemistry or separation, and basic techniques to access critical states of matter. Part II will follow in a subsequent volume and is meant to provide a description of applications with cited examples and potential areas for development. The hope is that sufficient interest is stimulated so as to encourage radiochemists to look to alternative technologies of this nature to
