Abstract: Objective To study the extraction process of lignans in Schisandra chinensis (Turcz.) Baill. and S.
sphenanthera Wils. by supercritical CO2 fluid (SFE-CO2). Methods The orthogonal experimental design was
used to optimize the SFE-CO2 conditions including extraction pressure, extraction temperature and flow rate of CO2,
which was guided by the extraction rate of total lignans. The contents of four lignans in the extracts of Schisandra
chinensis and S. sphenanthera were determined s
