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. © 1982, The Pharmaceutical Society of Japan. All rights reserved.
