Journal ArticleDOI
Tetraoxygenated naturally occurring xanthones
Valdir Peres,Tanus Jorge Nagem +1 more
TL;DR: This review, with 350 references, gives information on the chemical study of 234 naturally occurring tetraoxygenated xanthones in 12 families, 53 genus and 182 species of higher plants, and two which are described as fungal and lichen metabolites.
Journal ArticleDOI
Differential accumulation of xanthones in methyl-jasmonate- and yeast-extract-treated cell cultures of Centaurium erythraea and Centaurium littorale
Ludger Beerhues,Ursel Berger +1 more
TL;DR: A scheme for xanthone biosynthesis in the two cell cultures is proposed, which elicited xanthones accumulated intracellularly and a substantial increase in the activity of phenylalanine ammonia-lyase was not observed.
Journal ArticleDOI
Chemotaxonomical investigations of the genera Blackstonia and Centaurium ( Gentianaceae )
TL;DR: Methanolic extracts from aerial parts and capsules of plants of 5 populations of Blackstonia perfoliata and 99 populations ofCentaurium species (Gentianaceae) have been screened by means of TLC for the secoiridoid glucosides and the m-hydroxybenzoyl esters of sweroside.
Journal ArticleDOI
Isoflavones and xanthones fromPolygala virgata
TL;DR: Five isoflavones and two xanthones have been isolated from the roots of Polygala virgata and 5,7-dihydroxy-8,4′-dimethoxyisoflavone is reported here for the first time as a naturally occurring compound.
Journal ArticleDOI
Polyoxygenated xanthones of Centaurium littorale
TL;DR: The 13 C NMR and high resolution EIMS spectra of the two hexaoxygenated xanthones are reported and details of the TLC analysis are given.
