A new stilbenoid compound from the lianas of Gnetum microcarpum
Abstract:
A new stilbene, malaysianol E (1), together with five known stilbenes namely gnetol (2), gnetucleistol C (3), gnetucleistol D (4), resveratrol (5) and E-viniferin (6) were successfully discovered from the acetone extract of the lianas of Gnetum microcapum. The structures of these stilbenes were determined on the basis of spectroscopic (1D and 2D NMR) and MS evidence. This paper describes the structural elucidation of the new compound, malaysianol E. The chemotaxonomic significance of this compound is briefly discussed.

Conformation
The simplest example of a diene is 1,3-butadiene, an acyclic conjugated π system. At room temperature, the molecule exists as a mixture of s-cis and s-trans conformers by virtue of rotation around the carbon–carbon single bond. Although the s-trans isomer is...
