Systematic significance of xanthones, benzophenones and biflavonoids in Garcinia

Various parts of ten African species of Garcinia produce a range of xanthones, biflavonoids and lactones. Condensed tannins based on procyanidin are also a major feature of some of the species examined and these tend to be relatively deficient in biflavonoids. Distribution of compounds between plant...

Description
Summary:Various parts of ten African species of Garcinia produce a range of xanthones, biflavonoids and lactones. Condensed tannins based on procyanidin are also a major feature of some of the species examined and these tend to be relatively deficient in biflavonoids. Distribution of compounds between plant parts can vary markedly but, in general, the distribution of xanthones, biflavonoids and benzophenones among these and other African species relates well to classical taxonomic divisions. However, when Asian species are included in the analysis only the biflavonoids appear to show general promise as taxonomic markers within the genus. All three classes of compounds seem to possess value as taxonomic markers at the supra-generic level within the subfamily Clusioideae.
