"In the present study, the use of supercritical fluid extraction was investigated for selected compounds from the plant Japanese knotweed (Polygonum cuspidatum Siebold and Zucc.). The effects of parameters such as type of modifier, pressure, temperature and time on the extraction efficiency of piceid, resveratrol and emodin were studied. The optimal conditions were found as follows: modifier acetonitrile, 40 MPa, 100 degrees of Celsius and 45 min. SFE results were compared with those obtained by conventional Soxhlet extraction carried out for 4 h. The extracts obtained using these two techniques were analysed by liquid chromatography coupled with UV detection."@en . "3" . "Journal of Supercritical Fluids" . "NL - Nizozemsko" .
