Turmeric (Curcuma longa L.) was extracted with supercritical carbon dioxide (sc-CO2) and turmerones,compounds with strong biological activity, were concentrated using semi-preparative supercriticalchromatography (p-SFC) with sc-CO2. The extraction was performed at temperature of 40 C andpressures of 9–66 MPa. Influence of pressure, type of adsorbent and feed-to-sorbent ratio on the yield andconcentration of turmerones in p-SFC fractions was evaluated. Silica gel performed the best efficiency;the concentration of β-sesquiphellandrene in thefirst fraction increased more than 16 times, compared tothe feed, and the concentration of ar-turmerone and curlone in the following fraction was almostdoubled.
