摘要：

Nine 1,2,3,8-tetraoxygenated xanthones were synthesized. The structure of l,2-dimethoxy-3,8-dihydroxyxanthone, isolated from Calophyllum trapezifolium, was confirmed. The structure of a xanthone, isolated from Kielmeyera candidissima, as 1,3-dihydroxy-2,8-dimethoxyxanthone was shown to be incorrect. The possibility of a 1,2,3,8-tetraoxygenation pattern for the new xanthones isolated from Centaurium linarifolium was discarded. © 1990, American Chemical Society. All rights reserved.
