This work describes the extraction of glycosylated flavonoids from 'passion fruit' leaves (Passiflora edulis; Passifloraceae), using carbon dioxide in the supercritical state modified with chloroform, ethyl acetate or shortchain alcohols. Carbon dioxide modified with 10% methanol was shown to be the

✦ Synopsis
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.
