GC‐MS of volatile components of Schisandra chinensis extract obtained by supercritical fluid and conventional 

extraction. In this paper, the volatile compounds of obtained by different extraction techniques including 

supercritical fluid extraction (Schisandra Chinensis Extract), steam distillation (SD), Soxhlet extraction (SE) and ultrasound-assisted 

extraction (UAE) were investigated for the first time. 


The sample preparation procedure for GC-MS analysis of the volatile compounds was optimized and then 37, 45, 27 

and 37 compounds were identified in the samples obtained by , SD, SE and UAE methods, respectively. As the therapeutic 

effect of the traditional Chinese medicine is usually based on multifarious essential components or the combination 

of them instead of only one component, the volatile compounds were compared in groups with the extracts by SE, 

SD and UAE. This would be more reasonable to evaluate the effects of an alternative technique to extracting 

multifarious essential components. Among the identified components in the extract, 32 compounds were the same 

as that by three conventional methods, accounting for 90.5% of the volatile compounds identified. However, 

as the volatile compounds were classed into groups, it was easy to see that the oil extracted by was made up 

largely of and (52.1 and 27.6%, respectively), with less amounts of and other compounds, distinguishing from 

the conventional extractions.
