The extraction was performed at temperature of 40 °C and pressures of 9-66 MPa. Influence of pressure, type of adsorbent and feed-to-sorbent ratio on the yield and concentration of turmerones in p-SFC fractions was evaluated. Silica gel performed the best efficiency, the concentration of β-sesquiphellandrene in the
first fraction increased more than 16 times, compared to the feed, and the concentration of ar-turmerone and curlone in the following fraction was almost doubled.Workplace Institute of Chemical Process Fundamentals Contact Eva Jirsová, jirsova@icpf.cas.cz, Tel.: 220 390 227 Year of Publishing 2020 Electronic address http://hdl.handle.net/11104/0298656
