Abstract: To study the technology of supercritical CO2 extraction of Phospholipid from Polygonum multiflorum Thunb, the effects of pressure, temperature, time, kinds and content of entrainer on the phospholipid extraction were explored. The optimum technological conditions were identified with the orthogonal design. The optimum technological conditions were as follows: temperature 50℃, pressure 30Mpa , Folch reagent as entrainer with content 60% and time 120min.

Key words: supercritical CO, 2phospholipid, extraction
