The Constituents of Schizandra chinensis BAILL. XII. Isolation and Structure of a New Lignan, Gomisin R, the Absolute Structure of Wuweizisu C and Isolation of Schisantherin D

Abstract

A new dibenzocyclooctadiene lignan, gomisin R (4), was isolated from the fruits of Schizandra chinensis BAILL. (Schizandraceae) together with wuweizisu C (1)²⁾ and schisantherin D (12).³⁾ The absolute structure of 1, the relative structure of which has been elucidated by Liu et al., was defined by chemical correlation with dimethylgomisin J (2). The absolute structure of 4 was determined by spectral studies and chemical correlation with 1.
