[A novel lignan dimer from stems of Kadsura heteroclita]

Abstract

As a part of our search for bioactive material, the chemical investigation of the stems of Kadsura heteroclita led up to the isolation of a new lignan, heteroclitin R. The structure was elucidated on the basis of nuclear magnetic resonance spectroscopic data. Heteroclitin R was a new compound as a lignan dimer obtained from Schisandraceae family for the first time.
