Abstract

Supercritical CO2 extraction of Broussonetia papyrifera oil was studied.The effects of extraction temperature,pressure and time on oil yield were investigated by orthogonal test.The optimal extraction conditions were determined as follows: extraction temperature 40℃,pressure 30 Mpa and extraction time 2h.The composition of Broussonetia papyrifera oil was analyzed by gas chromatography(GC).It was showed that Broussonetia papyrifera oil contained plenty of unsaturated fatty acids,whose content reached 88.16%.The main component was linoleic acid with a content of 81.53%.
