Two new lignans named pre-gomisin (1) and gomisin J (2) were isolated from the fruits of Schizandra chinensis BAILL. (Schizandraceae). The structure of the former was elucidated as (2S, 3R)-1, 4-bis (3´-hydroxy-4´, 5´-dimethoxyphenyl)-2, 3-dimethylbutane (1) by its preparation from guaiaretic acid. The structure and conformation of the latter were elucidated by chemical and spectral studies.
