Preussianone, a new flavanone-chromone biflavonoid from garcinia preussii engl.

Abstract

A new flavanone-chromone biflavonoid, preussianone (1), has been isolated from the leaves of Garcinia preussii, along with four known biflavonoids. The absolute stereostructures were elucidated by chemical, spectroscopic, and chiroptical methods. The biological properties of the new biflavonoid against several bacterial strains were evaluated. © 2012 by the Authors.
