Abstract

Abstract: The technical system of oil extracting from passionflower ( Passiflora edulis Sims. ) seed using
supercritical CO₂ extracting equipmentwas studied. The op timal seed oil extractive processwas as follows: the
extraction pressure was 30 MPa, the extraction temperature was 45℃, the separation temperature was 40℃
and the extraction time was 70 min. Under these conditions, the extraction yield was 28.4%. Twelve compo
sitions of the oil was identified by gas chromatography2mass spectrometry (GC - MS). The main composition
was fatty acid and unsaturated hydrocarbon. There was 7518% of unsaturated fatty acids in total fatty acid and
1714% of squalene in unsaturated hydrocarbon

Key words: Passionflower, Passiflora edulis Sims., Supercritical CO₂ extraction, Seed oil, Chemicalcomposition
