Abstract
abstract a volatile concentrate of thymus herha-barona was isolated by supercritical c02 extraction with a fractional separation technique. gc/m s analysis of the various fractions obtained at different extraction times and fractionation conditions allowed the identification of the best operating conditions to isolate the volatile extract. a good extraction performance was obtained operating at 90 bar and 50^0c for 300 min. the optimum fractionation was achieved by operating at 90 bar and -10^0c in the first separator and at 15 bar and 15^0c in the second one. the influence of extraction pressure and of extraction time on the extract composition were also evaluated. a comparison between a hydrodistilled oil of thymus herba-barona and the supercritical extract is also given.
