Abstract:

Supercritical CO2 extraction was used to extract crude oil from the fruits of Schisandra chinensis (Turcz.)
Baill. The chemical composition of the oil was analyzed using gas chromatography-mass spectrometry (GC-MS) after
separation and purification by three-stage molecular distillation. The results showed that the major volatile component was
borneol (43.562%) in the first stage, and alarene (25.137%) in the second stage. 2-Chloroethyl linoleate (20.978%) and
9,12-octadecadie noic acid (65.835%) were the major components in the third stage.

Key words: Schisandra chinensis (Turcz.) Baill., essential oil, supercritical fluid extraction, molecular distillation, gas chromatography-mass spectrometry (GC-MS)
