A New Triphenyl-Type Neolignan and a Biphenylneolignan from the Bark of Illicium simonsii

A new triphenyl-type sesquineolignan, named simonsinol (1), was isolated from the bark of Illicium simonsii and its structure was elucidated based on the detailed analysis of its 1H- and 13C-NMR spectra. A new biphenylneolignan, named isomagnolone (5), was also isolated and its structure was determi...

More Information
Summary:A new triphenyl-type sesquineolignan, named simonsinol (1), was isolated from the bark of Illicium simonsii and its structure was elucidated based on the detailed analysis of its 1H- and 13C-NMR spectra. A new biphenylneolignan, named isomagnolone (5), was also isolated and its structure was determined by the analysis of the two dimensional (2D) NMR spectra.
