Supercritical carbon dioxide was used to extract lignans from seeds and leaves of Schizandra chinensis (Turcz.) Baill. Kinetics of the extraction was found to be controlled by intra‐particle diffusion of lignans. The extraction yields were approximately 96% of lignans from seeds and about 26% from leaves, both yields being based on the total lignan content determined from two successive Soxhlet extractions with petroleum ether and methanol. © 1997 John Wiley & Sons, Ltd.
