A new naturally occurring xanthone bearing rare oxygenation pattern from Hoppea fastigiata

Abstract

A new xanthone 1,3,6-trihydroxy-8-methoxyxanthone, was isolated from chloroform extract of the whole plant of Hoppea fastigiata and the structure was elucidated on the basis of spectroscopic and chemical studies. The xanthone molecule has an unusual oxygenation pattern (1,3,6, 8) and is of chemotaxonomic interest.
