Chemotaxonomy and pharmacology of Gentianaceae
TL;DR: A coherent theory for the biosynthesis of xanthones is postulated and used to group the compounds into biosynthetic categories and a comparison of the above groups with strict consensus trees based on molecular data and the new classification proposed by Struwe et al. (2002) is compared.
