ISOLATION AND FRACTIONAL SEPARATION OF TARRAGON ESSENTIAL OIL BY SUPERCRITICAL FLUID
Journal Title: Analele Universitatii din Bucuresti. Chimie - Year 2009, Vol 18, Issue 1
Abstract
The experimental results of supercritical CO2 extraction on tarragon essential oil at 50˚C and 90 bar are presented. The chemical composition and the yield of the supercritical extract are compared with those of the tarragon oil isolated by conventional hydrodistillation method.
