“…Compound A, mp 112-114°, was identified as 1 -hydroxy-3,5,6,7,8-pentamethoxyxanthone by spectroscopic data (hrms, uv, ir, 'H nmr) and by comparison with a sample prepared by monomethylation of 1,6-dihydroxy-3,5,7,8-tetramethoxyxanthone (1). This xanthone was recently isolated from Eustoma grandiflora (4).…”

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. The value of these groups of substances in connection with pharmacological activity and therapeutic use of some species is described. The structural formulas of 135 isolated compounds, and their distribution, are also given.

“…We report here that the «-hexane extract of the roots contains six 1-hydroxy-3-methoxyxanthones identified by their spectral data and those of the acetylated derivatives. They are, in order of elution from the silica column, 1,8-dihydroxy-3,5-dimethoxyxanthone (methylbellidifolin) (1,4), 1,8-dihydroxy-3,5,6,7-tetramethoxyxanthone (8-desmethyleustomin) (1,(4)(5)(6), 1-hydroxy-3,5,6,7-tetramethoxyxanthone (6,7), l-hydroxy-3,5,6-trimethoxyxanthone (9), l-hydroxy-3,7,8trimethoxyxanthone (decussatin) (7), and 1 -hydroxy-3,5,6,7,8-pentamethoxyxanthone (eustomin) (7).…”

“…In the family Gentianaceae, the genus Centaurium (1-6) is characterized by xanthones with a single aromatic ring (1-OH, 3-OMe), by the absence of the usual trioxygenation in favor of a new oxidative step, hexaoxygenation, previously found only in the genus Eustoma (7), and by the xanthone compound 8-desmethyleustomin, only found previously in Centaurium cachanlahuen (4), C. erythraea (1-3), and Centaurium linarifolium (5,6). EXPERIMENTAL PLANT material.-C. erythraea was collected in July 1983, in Macedonia, Greece; a voucher specimen is deposited at Laboratoire de Pharmacognosie de Grenoble, Domaine de La Merci, F-38700 La Tronche.…”
