Abstract

A new 12a-hydroxyrotenoid, boeravinone C, has been isolated from the roots of Boerhaavia diffusa L. (Nyctaginaceae) and its structure including the absolute configuration was determined based on chemical and spectral evidence. The 1H-nuclear magnetic resonance of boeravinone C showed unusual splitting patterns due to ABC spin systems. These splitting patterns were analyzed by a simulation method.
