XANTHONES, SECOIRIDOIDS AND FLAVANOIDS FROM HALENIA CORNICULATA

Three new xanthone glycosides and a rare flavonoid glycoside have been isolated from the whole plant methanolic extract of halenia corniculata (Gentianaceae).They were identified as 2,3,7-trimethoxy-1-O-primeverosyloxyxanthone, 2,3,4,7-tetramethoxy-1-O-primeverosyloxyxanthone, 2,3,4,5,7-pentamethoxy-1-O-primeverosyloxyxanthone and 7-O-primeverosylluteolin.Combined HPLC-UV and thermospray MS analyses of both dichloromethane and methanolic crude extracts permitted the detection of six other new xanthones, tentatively identified by on-line data.Among these, one was an aglycone, 1-hydroxy-2,3,4,5,7-pentamethoxyxanthone and five were 1-O-glycosides: 7-hydroxy-2,3,4,5-tetramethoxy-1-O-primeverosyloxyxanthone, 7-hydroxy-2,3,4,5-tetramethoxy-1-O-gentiobiosyloxyxanthone, 2,3,7-trimethoxy-1-O-gentiobiosyloxyxanthone, 2,3,4,7-tetramethoxy-1-O-gentiobiosyloxyxanthone and 2,3,4,5,7-pentamethoxy-1-O-gentiobiosyloxyxanthone.Systematic use of an in-house UVdatabase and complementary on-line MS data enabled the identification of 16 known secoiridoids, flavonoids and xanthones. - Keywords: Halenia corniculata; gentianaceae; xanthones; flavonoids; secoiridoids; aglycones; primeverosides; gentiobiosides; LC-UV; LC-TSP-MS.

A New Regiospecific Synthesis of 1,4-Dihydroxyxanthones

Several methyl salicylates have been found to substitute halogenated benzoquinones regiospecifically in the presence of anhydrous potassium fluoride.The resultant phenoxybenzoquinones were reduced and cyclized to highly functionalized xanthones of unambig
