Methods The chemical constituents were separated and purified by preparative thin-layer chromatography, silica gel, ODS, HP20 macroporous resin and Sephadex LH-20 gel column chromatography, and semi-preparative HPLC. Their structures were determined by NMR and ESI-MS spectroscopic techniques. Results Seventeen lignans were isolated from the ethanol extracts of C. fortunei and their structures were identified as shonanin (1), arctigenin (2), α-conidendrin (3), matairesinol (4), nortrachelogenin (5), epinortrachelogenin (6), (7'S)-hydroxymatairesinol (7), (7'R)-hydroxymatairesanol (8), (7'S)-hydroxyarctigenin (9), secoisolariciresinol (10), 4,4'-di-O-methylcephafortin A (11), 5-(3'',4''-dimethoxyphenyl)-3-hydroxy-3-(4'-hydroxy-3'-methoxybenzyl)-4-hydroxymethyl-dihydrofuran-2-one (12), cephafortin B (13), dihydrodehydrodiconiferyl alcohol (14), 7R,8S-4,7,9,9'-tetrahydroxy-3,3'-dimethoxy-8-O-4'-neolignan (15), 7R,8R-4,7,9,9'-tetrahydroxy-3,3'-dimethoxy-8-O-4'-neolignan (16), and threo-1,2-bis-(4-hydroxy-3-methoxyphenyl)-1,3-propanediol (17). Conclusion Compounds 3, 6, 10 and 17 were isolated from genus Cephalotaxus for the first time, and compounds 4, 5, 7-9, 12 and 14 were isolated from C. fortunei for the first time."/>
