Abstract: In a search of bioactive constituents from Guttiferae plants, we have isolated, purified by combining chromatography methods (Gravitation column chromatography, flash column chromatography and preparative chromatography) and elucidated a new pyrano xanthone tetrandraxanthone [1,3-dihydroxy,2′,2′-dimethyl pyrano (5′,6′,5,6) xanthone] (1) and seven known compounds cudraxanthone (2), lupeol (3), stigmasterol (4), thawaitesixanthone (5), 3-α-hopenol (6), isophrenyl benzophenones cambogin (7) and camboginol (8) from hexane and acetone extracts of the stem barks of Garcinia tetrandra Pierre. Their structures were established by spectroscopical data, including 1-D and 2-D NMR. These compounds are the first time reported from this plant. © 2008 Asian Network for Scientific Information.
