    Abstract:
    OBJECTIVE To study the chemical constituents in the root bark of Schisandra sphenanthera and their cytotoxic activities.
    METHODS The compounds were isolated and purified by silica, Sephadex LH-20 and semi preparative-HPLC and the chemical structures were identified by 1H-NMR, 13C-NMR and MS data analysis. The cytotoxic activities of the compounds were determined by MTT method.
    RESULTS Twenty lignans were isolated and deduced as: Matairesinol (1), 2-Hydroxy-2-(3′, 4′-dihydroxyphenyl)methyl-3-(3″, 4″-dimethoxyphenyl)methyl-gamma-butyrolactone (2), (+)-Nortrachelogenin (3), 2-Hydroxy-2-(4′-O-β-D-glucopyranosyl- 3′-hydroxyphenyl)methyl-3-(3″, 4″-dimethoxyphenyl)methyl-γ-butyrolactone (4), Nortracheloside (5), Burselignan (6), (+)-Cycloolivil (7), 5-Methoxy-(+)-isolariciresinol (8), (-)-Isolariciresinol 3α-O-β-D-glucopyranoside (9), (+)-9-O-β-D-Glucopyranosyl lyoniresinol (10), (-)-Secoisolariciresinol (11), Licarin A (12), Cedrusin (13), Matairesinol 4′-O-β-D-glucopyranoside (14), Pregomisin (15), Meso-dihydroguaiaretic acid (16), 7S, 8R-Erythro-4, 9, 9′-trihydroxy-3, 3′-dimethoxy-8-O-4′-neolignan-7-O-β-D-glucopyranoside (17), Gomisin M2 (18), Gomisin M3 (19), Pinoresinol (20). Compounds 1-3, 12, 15, 16, 18 and 19 showed cytotoxic activity against A549, HCT116 and SW620 cell lines with IC50 values ranging from 1.4 to 22.9 μmol·L-1.
    CONCLUSION Compounds 1-4, 6-12, 14, 17-19 are isolated from the plant for the first time, compounds 1-3, 12, 15, 16, 18 and 19 exhibit cytotoxic activities.
