Dependence of the camomile flower yield on the carbon dioxide quantity during isothermal supercritical extraction

Abstract

The dependence of the total extract yield of camomile flowers by isothermal supercritical extraction on the carbon dioxide quantity, at different pressures (80, 160 and 240 bar) at a temperature of 313 K, was investigated. A dynamic method was used. The experimentaly obtained results were described by equations which fitted the experimental results rather well. The equations obtained in this way represent a contribution to defining the quantitative dependence of yield on the carbon dioxide quantity used in the extraction.
