“…SC CO 2 extracts of Juniperus phoenicea were tested on exponentially growing human CD4 + lymphocytes (MT-4), baby hamster kidney (BHK-21), Madin Darby bos kidney (MDBK) and human cell lines derived from liquid and solid tumor. The results showed that the extracts obtained at 200 and 300 bar were cytotoxic against different cell lines and were active against a single-stranded RNA + virus [119]. SFE of volatile components of marjoram (Origanum majorana) and oregano showed a significantly high inhibition effects against E. coli, B. cereus, Listeria monocytogenes, Salmonella typhimurium and Pseudomonas fluorescens.…”

Supercritical fluid extraction (SFE) of plant material with solvents like CO 2 , propane, butane, or ethylene is a topic of growing interest. SFE allows the processing of plant material at low temperatures, hence limiting thermal degradation, and avoids the use of toxic solvents. Although today SFE is mainly used for decaffeination of coffee and tea as well as production of hop extracts on a large scale, there is also a growing interest in this extraction method for other industrial applications operating at different scales. In this review we update the literature data on SFE technology, with particular reference to flavors and fragrance, by comparing traditional extraction techniques of some industrial medicinal and aromatic crops with SFE. Moreover, we describe the biological activity of SFE extracts by describing their insecticidal, acaricidal, antimycotic, antimicrobial, cytotoxic and antioxidant properties. Finally, we discuss the process modelling, mass-transfer mechanisms, kinetics parameters and thermodynamic by giving an overview of SFE potential in the flavors and fragrances arena.

The chemical composition of the essential oil of Juniperus phoenicea from Algeria was investigated for the first time. The volatile oil was isolated by hydrodistillation in yield 0.80% and was analyzed by GC/FID and GC/MS techniques. One hundred and three constituents, representing 96.0% of the oil was identified, twenty-three being reported for the first time in J. phoenicea oil. The oil was characterized by the presence of high amounts of monoterpene hydrocarbons (62.2%) and by a lower percentage of oxygenated sesquiterpenes (8.8%), of which α−pinene (40.2%), α−phellandrene (14.7%) and elemol (3.9%) were the main compounds. Also the oil was characterized by the presence of three diterpenes constituents; manoyl oxide, abietadiene and cis-totarol amounting to 0.3%. A comparison with the composition of the oils of J. phoenicea (subspecies and varieties) of other countries reported in literature is discussed briefly.
