ABSTRACT
To study chemical constituents contained in ethanol extracts from roots of Machilus yaoshansis. Fifteen compounds were separated from the roots of M. yaoshansis by using various chromatographic techniques. Their structures were identified on the basis of their physicochemical properties and spectral data as twelve lignans(+)-guaiacin (1), kadsuralignan C (2), (+)-isolariciresinol (3), 5'-methoxy-(+)-isolariciresinol (4), (7'S, 8R, 8'R)-lyoniresinol (5), meso-secoisolariciresinol (6), isolariciresinol-9'-O-beta-D-xylopyranoside (7), 5'-methoxy-isolariciresinol-9'-O-beta-D-xylopyranoside (8), lyoniresinol-9'-O-beta-D-xylopyranoside (9), (2R, 3R) -2, 3-dihydro-2-(4-hydroxy-3-methoxyphenyl)-7-methoxy-3-methyl-5-(E)-propenylbenzofuran (10), 3, 5'-dimethoxy-4', 7-epoxy-8, 3'-neolignan-4, 9, 9'-triol (11), nectandrin B (12), and three flavanes(+)-catechin (13), (-)-epicatechin (14), and bis-8, 8'-catechinylmethane (15). All of the compounds 1-15 were separated from M. yaoshansis for the first time.
