SUPERCRITICAL FLUID EXTRACTION WITH CARBON DIOXIDE AT DIFFERENT PRESSURES

In this paper the influence of carbon dioxide pressure on supercritical extraction of Salvia officinalis L. was investigated. Supercritical fluid extraction with carbon dioxide was done for pressures of 80, 100, 150, 200 and 300 bar. It was concluded that with increasing pressure from 80 to 300 the bar extraction yield enhanced. GC/MS and GC/FID methods were used for qualitative and quantitative analyses of obtained extracts and essential oils from extracts.
